30 sherman magnum

[TXTrained]

I shoot 250 grain Atips in my 30 SM and my shooting partner shoots 245 grain Bergers in his 30 Sherman Mag.. I jump mine 5 thou. is all. My partner jumps his 25 thou. He runs his a little faster because he has a 2 inch longer barrel than mine.I run my ATips at 2886 fps. with H1000 or N568. My partner runs his 245 Berger LRHT at 2910 with N570.His is a tack driver.It has been the last 3 years.It shot great.He just pulled the barrel and is building a new one.,It had so many rounds on , (over 1500)it he was afraid it would go out in a Match. .
