mtnboomer, thanks for the response. Since my rifle is not semiauto - although I would like to own an M-14 or FAL
- I don't have to worry about how well it cycles. (Although, it does have to be able to cycle through my bolt action.) So, thanks for the response, but that really wasn't the question. The question is: if a factory loaded round has lower fps and ft-lbs specs than a NATO round, does it also follow that this round's CUP or PSI - whichever you prefer to use - is lower than NATO spec, and consequently, safe or safer to fire in a 7.62 NATO caliber rifle.
