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
