Thanks for the replies fella's.
I have been looking at trying some of the lighter pills out of my 7RM too, but it shoots the 168 Berger's so well that I have had a hard time trying out new loads
That's the problem though. I am having such a good time shooting my 7RM that it won't be to long before I need to rebarrel.
What is the effective range for deer sized game, if the shooter is proficient enough, of a 140-150 grain bullet out of the 7 STW? I am just wondering how much faster those 140 grainers lose energy over a 180 grainer?
