My rem 700vs isn't shooting quite well enough for me. Its holding 5 shot groups right around 1" with 40 50 and 55gr bullets but I am still not satisfied. I do know that this isn't terrible for a factory rifle by any means, but it can do better with some help. If i decide to have this rifle re barreled what twist will i have to go to to shoot the 75gr a-max bullets? And should i ackley Improve this cartridge to get the most out of this type of bullet or do you think a standard 22-250 will push the bullet fast enough? I am thinking along the lines of a long range prairie dog shooting rifle with one of my mcree aluminum stocks. Just an idea at this point as i already have a couple projects in the works. Lee
