Re: 7mm SAUM Rechamber/Barrel Life

And when the US adopted the M17 (the US Enfield) in ww1 with British style rifling, there was much criticism. But it distinctly outlasted the US type rifling favored at the time. Perhaps not quite as accurate but more practical in a battle weapon. But I am not sure this has much bearing on a solidly...

Re: 7mm SAUM Rechamber/Barrel Life

I cannot answer the question because I have not run both my Saum barrels past 800 shots each. My policy has been to use a standard 284 back to 800y, then the Saum at 900, 1000y although enthusiasm did get the better of me the last Queens I shot and I used the Saum right through. I reckon that going ...

Re: Silver Mountain SOLO ET's

When we tested the Mareeba SM target (4 sensor type) in Mareeba there were no active adjacent shots. The log file was used to record reported positions of impacts on the target which eliminated transcription errors and reduced the complexity of the task to something doable. Remember, there were over...

Re: Scope Advise - 900yd MOA

There is no doubt that a NightForce BR can cover the range from 300 to 1000y - even to 1200y for Match Rifle. BUT it has to be mounted with great care to successfully span this range of distances. One extremely versatile option is to use Burris Signature Zee mounting rings which have fine adjustment...

Re: Barnard action

I do not have any method of measuring the diameter of the extractor groove to the precision we are considering but I must say that I found the rims that I measured had a constant diameter. Which does not exactly prove roundness but it does give confidence.

Re: Barnard action

Interesting thread. Since I have a box of unopened Lapua 6.5x55 brass, I decided to measure the rims. No idea what year of manufacture. I used a good micrometer since I trust it more than digital calipers which read about 1/2 thou more. I believe the micrometer more than the calipers which was confi...

Re: Barnard action

I have never had a problem with Lapua 6.5x55 cases used with a standard Barnard P bolt. I think much of the brass is now made to 'US specs' on the case head anyway. As a matter of interest, you can achieve (139 Lapua projectiles) over 3000 f/s in a 30 inch barrel with 2209. 46 grains 2209 is a max l...

Re: Queensland Match Rifle

I wish I could have been there but am limited a lot by my health these days.

I enjoyed the company of Match Rifle shooters more than any others and would encourage other FO shooters to join in whenever they can.

Re: What calibre?

6PPC is a a dedicated short range rifle. Agree with comments above on it. Usually they are built up with slow twist barrels for very light projectiles which are useless for long range. 6BR maybe but again it is not really a competitive long range rifle. Pleasant to shoot and very accurate. BUT I que...

Re: Hydro die

A local Pool/Chemical shop sells it by the gallon but I do not think it is a good candidate. This is actually Anhydrous stuff and good for cleaning lenses thus leaving no residue. I suspect water is better. No matter what you use it will be messy and require through cleaning out and drying. Peter Sm...

Re: More on Barrel Tuners

Gyro, You can do much better than 'Peer Review' despite who is involved. Peer review has been debased by many called 'Scientists'. You scratch my back - I scratch yours. So both get more published papers and bring in more research money. Or these days often Advertising Money ! In one word, Science i...

Re: More on Barrel Tuners

Alan, I was going to post almost exactly what you said on change in MV due to rifle weight. I also think that the free recoil distance of only a few mm for a heavy rifle is such that the rifle is initially recoiling against air or loose clothing or a spongy recoil pad and the bullet has left the bar...

Re: Stock Rigidity

FWIW, I have seen a foresight Grub Screw on a TR barrel actually punch through the barrel wall after many shots. The barrel obviously flexed around the pressure point created by the grub screw and a small piece fatigued out of the barrel wall. In general, they are bad news.

Re: More on Barrel Tuners

Yes, absolutely correct, Barry. The names shooters have given to many things are in fact incorrect. Bit like the names for 'shooter's mirage' and 'degrees' for sight corrections. And it is NOT the velocity of the muzzle flicking the projectile that causes havoc, instead it is the direction change of...
