Re: 300wm or 7mm
I agree with AJ on the 300 wsm. I built one last year for a lightweight carry rifle and getting 3418 fps with a 150 gr bullet in a 24" barrel. That is all a 300 win mag will get and I am doing it with less powder, recoil, noise etc. A buddy saw mine shoot and bought a Tikka light and his does the same as mine. One hole accuracy at a hundred yards. It will not match the 300 win mag with heavier bullets but is close.
Predictions are difficult, especially when they involve the future
