7 mm rem mag and ramshot grand

[JamesWilson5]

Got a winchester xpr 7 mm rem mag with factory 26 inch tube. I was doing some chronograph reading using 150 accubond I ran loads till I hit pressure backed off 1 grain no pressure but my velocity was was extreme 3376 fps . Has anyone else had this kind of velocity

Nope. 3250 is all I could get with 150gr TTSX and h1000

My 7 weatherby is only 3300fps with factory ammo it blew my mind how much velocity it gained

Let us know what kind of grouping you get once you find your load. I'm using rl-26 but don't know how long it will last and looking for a replacement. Shooting 160 gr accubonds at 3100 under 1/2".

I've seen that kind of big jump in speed with bad carbon ring fouling. Have you bore scoped it?

What is the barrel life on those scorchers that is moving in any language.
