HI,

I have been told that barrel rifling (rate of twist)will affect the accuracy of bullets of different grains. I do not know rate of twist on my rifles, maybe someone could help me out. i have a remington model 700 bdl stainless with 25 1/2 inch barrel chambered in 300 weatherby mag & browning composite stalker 388 with a 26 inch barrel,
this might be a long shot but does anyone know which grain bullet would be best in each rifle or am I looking into this area to much.

THANK YOU
