Even when the restrictions are finally lifted, I'm going to think very carefully about how I interact with other people...........

Like Pops said this will be the attitude of many. Over the past 3 weeks I’ve got used to giving people a wide berth, even those I’ve know for years. It’s going to take a while for us to adjust to being closer.

Nobody is expecting to shoot in the very near future but cancelling that far ahead maybe unnecessary and may cause themselves extra work in rescheduling everything..

You'd think a month ahead is quite a long time for things to take a turn for the better...

 

They had no choice about cancelling competitions such as the Imperial. Imagine the cost if they continued to plan for it, take all the entry fees etc, etc, and then had to cancel. 

They no doubt realised we’re in this for the long haul, and as much as I wish it to happen, things won’t take a turn for the better, such that we can go out without concerns, until mid-summer at the earliest.

PMA (Positive Mental Attitude). 

The NRA have cancelled all competitions and training. My best guess is they will start taking range bookings as soon as it is safe to do so.

In the meantime, I’m not even thinking about the things I would be doing in a normal situation. I know I’ll get back to shooting sometime (assuming I’m a survivor), so it’s on hold for the duration.

We are lucky inasmuch that we have open fields and a nature reserve within 4 minutes walk of our house so my wife and I can take our dog out for her walk in relative safety.

It ain’t all bad.

How about a hot glue gun to fill a primer pocket on a sized case?

That sounds a good idea. I’ll give that a try later, especially now I have so much ‘lockdown ‘ time on my hands.

If you don't have a snap cap, a fired case (with spent primer still in) will give a bit of protection.............better IMHO than an empty chamber.

Pete

That’s what I do.

Why not fire a primed case just to keep things authentic and keep the neighbours awake? Just kidding 😇

My barrel life is now extended by several months.

OCW is best done at 100m because it’s easier to spot the group sizes with different charge weights. Remember, OCW is all about finding the best group within the middle of a suitable series of groups, where the series of groups all show little dispersion...particularly low vertical. I’m not overly concerned either by chasing low ES/SD. It’s nice when they are in single digits but it’s not essential. Stable group size is!

Muzzle velocity really comes later as it’s important for your ballistic calculator. So I don’t see measuring MV really that important in the initial phases of OCW testing. And actually, I prefer NOT to use the Magnetospeed during initial OCW as strapping it to the barrel will affect harmonics and this group size.

I therefore run my OCW to find the best group, then run a second test on the same group (same bullet and powder charge) but with different seating depths to fine tune (if needed). Lastly I’ll stick a Magneto on the end to record MV which I store in my Kestrel. Done!

With regards to measuring MV using electronic targets, I couldn’t say. It’s likely all down to the system being used and how accurate it is. I would hazard a guess and suggest it’s not going to be quite as accurate as a LabRadar or Magnetospeed, but it might give you a ball park from which to work your Kestrel.
 

 

Absolutely spot on. 

Just a note about SD. Many shooters chase an elusive single digit SD and it is totally unnecessary. Because SD is a measurement of a population dispersion from a group mean, it is meaningless for low population counts. Statistically the acceptable minimum population is over 30 data points.

This is an interesting question. 

Berger provide a twist rate calculator which gives optimum rates for different bullets weights. Most bullet manufacturers give optimum twist rates for their bullets but this is about stability, not necessarily accuracy. You would think the two go hand in hand but we all know that’s not necessarily true.

Many top shooters believe the slower you spin a bullet within the recommended twist rate for a bullet weight, the more accurate it will be, especially at high MVs. For example, many top FTR shooters use a 1:14 twist barrel, which at 3000 fps has an SG of only 1.17 and is just marginally stable, but these guys consistently achieve groups of less than 0.25 MOA.

The other consideration using a faster than recommended twist rate. I was told by a well respected gunsmith that if you spin a bullet to fast the phenomenon of precession creeps in. This would obviously affect accuracy but how would be seen in terms of, say group shape?

Next year is no good to me Andy 🙄. Let's just say next month and see how it goes 🤞😉

We should be so lucky Neil. The timescale to getting back to normal is bound to be slow. Firstly there needs be a significant drop in the number of infected individuals. At this point in time it’s still rising exponentially despite government mandates and advice on social distancing and self isolation etc.

The way I understand it, from watching TV expert panel discussions, if the current measures are effective, we’ll see a plateau in the number of infected cases, then a drop off.

Logically, I can’t see that happening for months.

I think it depends to a certain extent on how much you want to spend, what sort of volume you intend to load and just what sort of accuracy you are looking for. A good beam scale, costing maybe £100 should work very well, certainly as accurate (and often better) than any of the electronic auto dispensers (RCBS, Lyman, Hornady), costing £200-400. A good beam scale will still be working just well in 10, 20 or 50 years but most of the electronic scales/dispensers will be in the bin within 10 years, and often half that,  in fact I believe most are only under warranty for 12 months

If time is of the essence, and you are not too concerned about a few kernels either way with your charges, then something like a Chargemaster might be just the thing for you. 

If you're looking for speed with even more accuracy (at a cost £6-900) then the Auto-trickler, which combines an automated powder measure, a powered trickler and a high quality lab grade digital scale into one package is the way to go.

What ever system you use, you need to bear in mind that a single kernel of something like Varget weighs around .02 of a grain, about 5 kernels to 10th grain (and many powders are considerably more chunky) so having a scale, as used in some atomic research lab that resolves to x figures, unless you intend to cut kernels in half, is a bit pointless.

If you do decide to go for an electronic set up it's always nice to have good beam scale to fall back and as a cross reference. You won't load better ammunition than you can with a good beam scale.

 

I still use my tuned Redding beam scale with its USB micro camera linked to my laptop. Awesome.

Contact Harwell Rifle Club or Ridgeway Rifle Club. They both have access to Otmoor  range.

PM me and I’ll send the secretaries email addresses.

The above describes a very common email ‘Phishing’ (pronounced FISHING) scam.

A hacker creates an email that looks to be from a reputable company and sends them out to a whole bunch of email addresses, looking for someone to ‘bite’. The email ‘From’ name can be customised to anything you like, so people look at the ‘from’ name (eg Amazon or online banking) and look at the Amazon branding of the email and think it’s genuine. Often scammers simply take a copy of a real email (like a screenshot or scrape the email code), but change the links inside to point to their ‘scammer’ email inbox or website.

It works by the person receiving this ‘Phishing’ email, thinks it’s genuine and clicks a link in the email (usually instructing them to login to their account or such like) then get directed to the scammers web page where they harvest login details from people who think they’re logging into the real site.

My number one golden rule is NEVER to click links in an email that I didn’t specifically request to be sent to me. 
So if Amazon or my online banking send me an email out of the blue, I will always visit the website directly (via my Google Search) and login directly. I will never click through from an email...even if it is completely genuine.

Its the only effective way to bypass Phishing scams. Having security software doesn’t mean they pick up on these bogus emails...many of the hackers are very clever and will often find ways to bypass the security. The security only fixes known problems or loopholes. They will fix one things when ones are found and exploited. Scammers are always a step ahead of the security firms.

The way I was caught was not through a Phishing email. This is why it was so canny. It was done while logging on to that particular email address.

If it was via an email link I would not have been hacked. My IT friend said that scammers have wised up to the email phishing link and have modified to the method that caught me.

They take a common email ISP, one that isn’t a subscription, (they prey on the the free ones) let’s say @xyz.com , and set up a fake website that is basically what is referred to as a “key logger”.

Every X amount of hits someone accidentally hits it and the log on password is recorded. Job done.

So, Catch is correct, but be mindful of subtle changes on your email log on screen.

Could you explain what happened in a bit more detail please? Old link to what?

Cheers

Pete

Pete,

Without giving too much detail, because I’ve taken a lot of extra security steps to ensure it doesn’t get repeated, on that email address it always opened on a BT page first. I had to log on that which then diverted me to the email page. 

The scammer had replicated the BT page with the addition of the words “Oops, it looks like you’re using an old link, click here to be redirected.”

It’s quite a common ploy. I only found out how the hack was done when I discussed this with an IT friend ..

My Amazon account was hacked last August. It was exceedingly well done. I logged on to my email and a page popped up stating I was using an old link. I then followed the link provided and unbeknown to me this was a fake web page which allowed the scammer to obtain my email password.

All he/she did was read my emails until they saw a lucrative transaction, which was on Amazon.

He took goods to goods to the value of £500 to be delivered to a box at a local Premier Inn.

By sheer good fortune, it was only through recommending an Amazon product to No I Deer that I discovered the fraud. I couldn’t log on to my account to send him the link. I contacted customer services who told me what I had supposedly purchased and they cancelled the orders and suspended the account.

The hassle sorting it all out was a nightmare. The police were involved and Action Fraud. Luckily I didn’t lose a penny. But I never follow web links now, no matter how plausible.

This raises all sorts of concerns about buying firearms related goods through any shooting forum.

in the time I’ve been a forum member I’ve got to know many other members so buying or selling to them again is not a concern. But what about those not dealt with  be? It’s relatively simple to sort out obvious trustworthy members by their association with other known members. But it still leaves a few unknowns.

It’s very difficult to spot scammers, but you tune into clues if you’ve been close to being hooked in before.

For me, the key learnings from this episode is:

1. Never meet in a remote location. Choose a site like Bisley or Diggle.

2. Don’t invite an unknown to your home.

3. Assuming 1 and 2, never pay until you’ve confirmed the item is genuine.

You have a pm.

I have just looked at a copy of the DIO License form for my old club.  This was issued 2018  by DIO West & Wales and is a standard MoD form

"DE FORM 5665 (F/Lands/434) (Version 3.0 — Jun 06)"

Section 10 (2:  ensure that all members and authorised spectators while on the premises behave in a proper and orderly manner and that no disorderly person is permitted to be or remain on the premises and that without the permission of the said Officer no child under the age of 16 years and no animals are brought on or allowed to remain on the premises

The "Officer" is the Range Commandant.  This is Maj. Jim Salisbury I believe.  Good luck with getting anything out of him 😉

Ironically, through a round about route, I had a phone call from Jim Salisbury yesterday where I outlined the details of the query. Subsequently, I received an email from him saying he was passing the request to the Range Officer at Sennybridge for clearance. His tone was positive and hopeful but we’ll see.

Ah, many thanks for the explanation. Now I understand why Popsbengo disagrees with it, and I agree with his logic.

I won’t hijack your post any further by elaborating on my load development methodology.

OCW "The right way" ??  Dan Newberry I presume.

Nice shooting Catch22 but each to his own.  I get similar results shooting groups of five in one weight, then five more at another weight etc.

I don't buy the rational for round-robin shooting 'spreading the errors across all groups equally" so thereby reducing the effect.  Voodoo statistics.

Regarding charge weight increments:  0.1gr is  0.11% of the likely load of 95gr for a .338 LM.  I do not buy the idea that one could resolve the difference from all the other factors.

Forgive my ignorance, but what is the round-robin method as opposed to shooting groups (3 or 5) in charge weight increments?
