what is the best chronograph to buy?

[longbow3]

hi all,

newbie here would like your advice on what is the best chronograph to buy?

thx Ray

These are suppose to be very good http://www.magnetospeed.com/pages/rifles

Yep they're great. I've got the V2 which I've completed my load development with and will be selling next week.

Another vote for the Magnetospeed, cracking bit of kit.

 

Used to hate the chew associated with chrono work but using this is a breeze with everything being done from the firing point.

+another vote for the Magnetospeed very accurate, really quick and easy to set up, it's a little pricey to buy but worth it.

( Review comparison) from Longrangeonly 16 June 2013:google and read:

 

"Oehler 35,Magnetospeed,Super Chrono"

 

Detailed tests ,which confirm the high regard Magnetospeed has here.

Another vote for Magnetospeed. Brilliant and easy to use for nearly everything (except pistols).

 

Just be aware the V2 doesn't work well with subsonic velocities, (according to the manual, velocities below 1,000fps). I only discovered this while working on a subsonic .308 load.

 

I think the V3 may have addressed this issue, but not sure.

I did have some issues with this but after some tweaking of the "custom bullet" settings I've had it reliably picking up shots down to 800fps with my .45ACP in both lead and plated bullets.

Would a V2 work with my .308 ASE Utra northstar? Just looking at specs and it says will work up to 2" diameter. I'm pretty sure my mod is larger than that, probably more like 60-65mm (guess)

Yes I found I could get it to work by increasing the sensitivity to the bullet, too. I haven't tried it with a .22rf and subs, yet, though - that might challenge it, I suspect.

 

Brilliant bit of kit though - so much easier to use than anything light-reliant.

The only issue I've found with it is that everyone asks me why I've got a bayonet fixed

Hi Gents.

Sorry if this is a silly Question.

Does the Magneto Speed alter Barrel Harmonics? Can I load test for Accuracy with it fitted as I would use a traditional Chrony? It worries me that I would develop an Accurate load with it fitted only to find things go Belly up when removed.

 

Thanks.

Nick.

Nick,that's a very sensible question.Most user reports seem not to be concerned-or much with POI issues.

But as with any change on/off barrel,you would be very wise to just check with a couple of shots,with the load,with it off-it should not invalidate the load development.

I've got my V3 working with .177 air rifle pellets at around 700fps, not sure why this is as the MS works off magnetism but when I tried to test my air rifle indoors with it I couldn't get it to work, I just got error messages but when I took it outside it worked fine!

[forbie]

I ordered one a V3 in April they said it was out of stock and would be sent when the new stock arrived along with a scope leveling system. Surpirsed today to find that when I went to the web site the latest shipment was sold out and waiting for delivery again in 2 to 3 weeks. NOT a happy bunny.

yes it does. i'd advocate load development then checking velocity and es etc. etc. some guys have advocated no difference but that was on hv taper barrels. i'm not sure i'd like to chance it as everything has an affect.

[longbow3]

many thx for the great response to my question

looks like it will be the v2 for me

Major Disorder can I buy your one??

[Gary C]

Gents

V3 will be in stock at the end of this week, Forbie we are sorry that you had to wait, please PM me with your details (which I am sure we have but I want to check) we severely under estimated the demand and all our units that originally arrived were virtually pre-sold.

 

Regarding harmonics:

 

The POI may alter with the bayo depending on the barrel and profile, however your group size will not be affected, the main cause of the POi change is the associated muzzle blast exiting the muzzle and passing over the bayo.

 

I always test a load with the bayo removed after load develop just to make sure and so far it has not changed.

 

Regards to all

Anyone who has played with the browning BOSS system or similar will know how a small change in weight on the end of a barrel can drasitically alter the group size and POI. A chrono fitted to the barrel at all is a terrible idea. If you just want MVs then fine, but I wouldn't attempt to do load development with it fitted. I really only use a chrono during load development and I wouldn't want to waste bullets just obtaining the MV so it's not for me.

 

I can't imagine it's not possible to stop the thing moving either under recoil either which would mean even shot to shot consistency can't be maintained. The idea of the magneto chrono is great, but there must be a better way to implement it.

[Gary C]

Forbie,

 

I have checked your order which was made on the 24th April, we did notify you that the V3 was out of stock and offered to cancel your order until it arrived, you declined and agreed to wait.

To make it very clear we have not had another delivery since the first one.

the expected delivery was delayed due to extreme demand worldwide, so we did not fulfil any other orders in front of yours.

The V3's are now on the way to Houston Airport and should be here by the end of the week ,yours will be first out the door.

 

With regards

c18arch,

 

Not found the group size changes from on to off.

 

If put on correctly unit does not move,

 

POI shift, possibly dependant on the rifle, but this does not effect my reloading method/checks in any way, sensible inbuilt checks and balance etc. to whole process assures this.

 

Like anything, I tried before I bought to remove hyp/rumours from process, anechdotal does not work in accuracy/consitency.

I'd generally agree with these findings having used all three versions extensively since Gary C first brought the V1 and V2 into the country last year. A lot depends on the barrel weight and presumably rifle bedding too. I've not tried it on a skinny barrel sporter firing a powerful cartridge - I would expect to see a substantial change between on/off here.

 

On a 308 factory Varmint weight barrel (around 'Light Varmint' weight on custom barrel profiles), it's mostly elevation change to POI with a smaller effect on group shape and size. The heavier the barrel, the less effect on both aspects. I see a little of both effects with 32-inch 'Heavy Palma' profile 308 barrels. As Gary says, it's sensible to do the final fine tuning of the load alongside getting the final sight zero with the device removed.

 

I was alongside Adam Bagnall on a Bisley F/TR practice / training session last summer, him string-shooting shooting 155.5 Bergers while I spectated with a spotting scope, at 1,000 yards one day last summer and he strapped a V2 on half way through the session. I fully expected a bit of sight adjustment, more likely a lot at this distance, would be needed, but no he just carried on shooting 5s and Vs for maybe ten shots until he'd got enough readings to be confident of the ammo performance. That was on a VERY heavy fluted Broughton on a very well bedded RPA action.

 

So far as their moving is concerned, the only combination I had a (slight) problem with was a Howa 1500 Varmint Stainless with a fairly sharply tapered barrel profile and a finish that seemed to be very slick so the strap doesn't grip as well as on most surfaces. That was with an early V1 model where it was a bit of a struggle to get the securing strap really tight. The original V2 was easier to lock on and the new V3 has got a really improved securing arrangement. I believe the VI/V2 models are also being upgraded and I'm pretty sure Gary says that the later strap assembly can be purchased for retro-fitting if the owner really worries about this. The giveaway of something happening on the Howa would be a mid group elevation change as the strap resistance was overcome and the bayo jerked forward a little on the barrel under recoil affecting subsequent shots. But I'll emphasise this was with an early V1 model and the current arrangements are in a different league. Finish doesn't seem to be an issue - I've used Magnetospeeds on everything from highly polished bright steel to Cerakote painted barrels.

I'm still waiting for more details on this:
