I had a friend that was a competition shooter. He told me that the less comtact with the rifle, the better. Well it worked great with my .223 but now I am shooting a .308. If I use the same method with the .308 that sucker will kick me like a three legged ninja. What is the rule of thumb on this madness? I am getting old enough that I don't enjoy getting rattled around, but I love shooting the .308.
