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...

Re: tell me about tuners for fclass

I used a muzzle weight - well forward - on two 284s. They shot extremely well. The way the weights were attached actually squeezed the bore slightly at the muzzle which may also be beneficial. I believe they did improve accuracy and also improved the recoil characteristics of the rifles. They could ...

Re: tell me about tuners for fclass

I know of many rifles without tuners that can shoot 10 Xs. Having said that, I will not say tuners are of no use. But I see a lot of people who simply use them as another excuse in the book of 1001 excuses - damn - it was not my fault - my rifle must have gone out of tune. The one thing that really ...

Re: Wichester M17

Well, why not an historically accurate revamp revisiting the M17s roots. The M17 is simply an Americanized P13/P14 originally designed for the 0.276 Enfield cartridge which would be on a par with today's top non magnum 7 mms. It would be competitive today with good brass. So would the Ross 280. Some...

Re: New Bushnell Tactical Elite Scopes for F Class

A focusing problem as described does not give one much confidence in manufacturing tolerances and or quality control in other areas of the scope. BUT it may not be hard to fix this problem. Scope Makers always have various methods of adjustment for the Focus Range. The big problem is finding out wha...

Re: 6.5 Creedmore - anyone?

Since no one else has answered about loads for the Creedmore 6.5 for 140s and using 2208 powder I will throw this in. It does not directly answer the question but may be of use. 36 grains of 2208 in a 6.5x47 behind 139 grain bullets is a fairly safe starting point. 37 grains is better but pressure r...

Re: 6.5 Creedmore - anyone?

An interesting but maybe irrelevant observation. The 6.5 Creedmore is very close in length to the Jap Arisaka and also the Italian Carcano although the last one usually was loaded a bit down because of the rifle it was in. Sort of full circle. That is comparing case size. Shape is different of cours...

Re: 6.5 Creedmore - anyone?

I recently played with a 6.5x47. It did shoot well but I cannot get the velocity I want with 139s or 140s without degrading cases more than I want. Without having tried a Creedmore, I suspect it will be marginally better and today if I made the choice it would be a Creedmore over a 6.5x47. At the ti...

Re: Alpha munitions brass

Gyro wrote Peter. Please define your last sentence ? And has ANYONE ever properly tested case weight variation vs long range accuracy ? If we use Lapua cases we need not bother weighing ? I do and don't weigh them. I'm waiting for that guy Bryan to publish some test results. Has anyone tested. YES. ...
