Help : FR-8 .308 Win Load with A No. 9

I hate to totally disagree with you here on the pressures of the 8mm Mauser cartridge, however, I do.

Any cartridge can be loaded to any pressure if your dumb enough to do so. My point was, and still is, that the original military load for the 8x57 Mauser was (1888 on)for the .318 bore, a 215 grain projectile at 32000 PSI, in 1905 this load changed to a 196 grain projectile at 34000 PSI in a 323 bore, some 170 and 150 grain loads were issued to facilitate carbines in an effort to reduce recoil but were discontinued. The earlier rifles (pre 1905) were free bored to accommodate the new round and are stamped with an 'S' to designate the Spitzer projectile. Enough of the 8mm, all of the above can be found on line or in any decent reloading or cartridge book.

As to the 7.62 FR7/8 or Cetme made conversions, They have a relieved chamber in line with the semi and full auto military issue rifles of the day, H&K as well as the Cetme s/a's. Thus the FR7/8's were chambered the same, hence the comment that this will often split cartridge cases, especially UK, USA and Australian made cases, these have a closer manufacturers tolerance when compared to the Spanish and eastern European countries manufactured rounds.

We can bounce what magazines and past tests say around all day all day. But, the bottom line, from the original German Defence department's own annuls is that the standard post 1905, 8mm Mauser round generally had a 196 grain projectile with a 34000 PSI rated pressure and was the “standard' military issue for that caliber. And the Cetme (factory) 7.62 chambers were all relieved with some free-bore,to (in bolt rifles) reduce pressure and aid extraction, and in Semi and full auto to aid extraction in adverse conditions, heat, dirt etc. How do I know. I was an armourer responsible for proof and field testing ammunition and cartridges from countries around the world as training aides for the Australian Army for 35 years. please feel free to add your next (erroneous????) comments.

have a good day y'all
