I’m afraid the tacky stickers had to go ……..

I’ll take the magnum please 👍

Norman certainly had bases (steel for the m82) and rings in fact pretty much everything you’d need - bottom metal etc

I bought an original M82 but did not have the diopter sight and they were able to make one up for me.

ZF69 6x42 was I believe the common original scope but I’ve seen them with pecars too.  I managed to find a ZF69 from an eBay seller in Germany but I’ve got a S&B PM1 on there at the moment.

Have fun 👍

I had no clue that powder coating cast lead bullets was a thing . I (and my lever actions) obviously don’t get out much as I was finding articles back beyond 2015. 

Intersting stuff.   I’ve only played with copper washed lead to try and cut down on barrel leading and found them to be very soft. 

I don’t particularly want to get in to casting at this point.   Is there a recommended UK source for pre powder coated hardcast bullets?

Well suited the the Welsh badlands Ben!

Is that the Ranger Point forend?

We obviously need to hear more about the multi colour rounds ……

Tony

I’ll take that please 👍

I had mine done a couple of years ago Dave.

The halos disappeared for me after a few months, I think your brain just tunes them out.   I don’t even think about them now and I just drove 300 miles overnight. 

I find using a FFP scope a crisp reticle image can be sensitive to head position as you have, as you explained, multiple concentric lenses.   I find myself tweaking the rear ocular setting on occasion especially for ELR to get a perfect image.

I do find myself hitting the light switch earlier as my pupils don’t seem to dilate as much as I recall in dim light. 

Being able to see turrets/charts/phone/kestrel without reaching for the old man glasses outweighs any other inconvenience!

So, there seems to be a real absence of understanding of the way statistics work.

There is no minimum number of samples for a meaningful results, what counts is confidence level generated by the margin of error, you keep taking data until you achieve the confidence level that you desire, and you can do this with 4, 5 or 6 samples, as long as they are representative.  More samples will increase your confidence but it's not linear and quickly becomes the subject of diminishing returns.

So for my data, taken at 37.2gn and running it through a stats calculator I have an average of 2,682ft/s.

From that I get a confidence of 68% that the results for the population will be 2,682 ± 2.49, and a 99% confidence that the results will be 2,682 ± 6.41.

I'm afraid that that is just the way maths works.  

Anyway, I got an answer to my question elsewhere so I will leave it at that.

You seem to have Googled Standard Deviation, now it’s  time you move on to Google Standard Error  to understand the impact of sample size on the relevance of your SD …….

Glad you are happy though 👍😉

I’m still consuming rounds I bought a fair while ago.

Is this first round pop or genuinely supersonic?    

Warmer nights should be helping with the speed of sound being higher ?   (Correct me if I’ve got it the wrong way round, I’ve had a couple of gins 😂)

Get a few over a chrono and let us know what you are seeing. 

Tony

I’ll take those please, PM on way 👍

1000 at Chobham Ridge as regularly as you could wish …..

The last 3 items I have ordered privately have all sailed through without duty or VAT.    

Commercial shipments seem very slow and I suspect we are being given some slack to keep the backlog manageable.

Just looking at another order - you know what will happen ….. 😖

Now that did make me laugh 😂

I only have the gun back 4 months! And the bore snake only does an oil clean out after being out of the safe even if it has not been fired on a shooting trip 

So how does it shoot ? 

Useful info.

That hardness tester may have been the bargain of the year 👍

Tony

edit - Apologies, I just read your back order comment, seems you already found them !

These guys do some great upgrades and will ship to the UK.

The ultra mount with case ejector setup, roller handle and primer catcher makes a great combo.

Try to ascertain if the underside of the bolt is dragging on the mag lips - a swipe with a sharpie maybe...

Does the bolt cycle differently with and without a mag?

I had a similar problem with a spikes upper on my existing lower and it just needed a tad taking off the top of each mag.  The slight drag was slowing the bolt just enough to cause an issue.
