Have any of you used the Managed Recoil Loads? I bought a box but haven't tried them out yet. I plan on trying them out in my Ruger M77 30-06. I'm not that big, and shooting once out in the woods is OK, but shooting targets for fun at the range is not fun on my shoulder. The guy at the gun shop where I bought them said I would lose some out past 150 yards. I usually only hunt in woods anyway, so my shots are rarely longer than 70 yds or so. Will these be ok? They only come in 125 grain for the '06.
