I am just starting to reload and wondering what bullet weight I want to use in my 1:9.5 twist savage. I currently have a box of 139 gr sst but going elk hunting in Idaho this fall and want a little more but not sure what my barrel can stabilize. Looking at the 162 gr eld-X and the 168 gr vlds! Can by barrel stabilize those bullets? Plan to use imr 4064.
