Briman,

Glad that I didn't upset anyone. That sure wasn't my intent. One of the nice things about this site is that the members are mature enough to discuss disagrements and attempt to learn from one another.

The Remington rifle doesn't have a buffer system. Gas drives the bolt to the rear and a spring drives it forward again. Unfortunately, I learned that the wrong powder can dsamage a Rem 742 the hard way. I picked one up years ago, when they were new on the market. I had a whole lot to learn back then, and sites like this wern't even a dream. Since I had had good luck with Du Pont IMR 4350, I tried it again. It is quite possible to really mess that rifle up, big time, with the wrong powder. Thank God I had learned something by the time I bought a 7400. H-4895 worked fine.
Between the 7400 and a 700, I learned a little about velocity loss due to the gas operation of the 7400. I got the impression that W-760 is to slow for use in a 7400, and IMR-3031 is the quickest burn rate powder that should be used.

Nice visiting with you. Good luck and God Bless.
