And, something additional. By the way, how did the Sellier 147 grs .308 Win. Competition, Art.Number 2908/2, perform in a 7,62-Nato-Enfield, for example an L42 A1 ? bangbang
Because this load was described as an quite accurate on from one of our dealers here, last year.. . The"green box".

As a replacement for a RG-Load L2 A2, for example. In some way.. I found a box of this stuff last week in a shop, as a surprise.

NATO STANAG 2310 is pretty loose about the projectile weight. From memory, and weight between 140 and 170 grains can claim to be in accordance with the STANG. Most countries use either 144 or 147 grains, but one US round (M59 I believe) was 150.5 grains. US M80 ball has a stated muzzle velocity of 2809 fps, Belgian SS71 is listed at 2735 fps, Good luck with your load development

Somebody here will know better than me but..............

Many Fultons regulated 7.62mm rifles were proof tested at 19 tons & intended use with a 144 grain bullet vs the current 20 ton using 155 grain one.

Does using 155 vs 144 bullet in a 19 ton proofed 7.62mm action pose any risk? some say yes, some no? whats the view of that here? any????

20 tons is 40,000psi and the maximum pressure for .308/7.62 is over 60,000psi, so I can't see why it would be dangerous. Why would Fultons have 7.62 rifle proofed at 66% of its maximum proof ??
Or am I missing something. any????

Many years ago a club member had a 7.62/.308 bolt action pistol made up. When he took it for proof he was asked if he wanted it proofed as a 7.62mm or .308. He asked what the difference was and was told "a ton". One was 19 tons and the other 20 tons. I don't know which was one was 19 or 20 tons.
Regards
Peter.

.308 is usually higher proof

20 tons = 40'000 PSI.. I'm not sure how works that? Respectively goes together.. . Please.. 🤔

It depends of the pressure which the load causes basicly.. Some 155 gr-loads produce higher pressure than others.. As with other bullet-weights.. The higher the bulletweight is the more difficult is staying within moderate pressures, usually.

Do you know why RG no longer supply civilians and the NRA?
The Army used to "pay" the NRA in RG ammunition for the use of the Bisley ranges for their International skill at arms competitions. It was this 7.62 RG that was the issued ammunition for the Imperial. The sale of surplus RG ammunition on the civilian stopped for the simple reason that there wasn't any store of ammunition slowly reaching its shelf life. The series of recent conflicts meant that rounds were going down range and not sitting in storage. In fact the Army bought ammo from RUAG for training because it was using more than RG could produce at the time.
