The ones they have now might be really good, but I remember right after they first came out I shot a friends a-bolt in .300 wsm with a sims pad on it. I rember thinking "durn that thing kicks like a mule". I have pachmayrs on my 2 magnums andI love 'em. I have an M77 in 7mm rem. mag. that I got new in 1986 and that thing was a booger from the bench, I put a pachmayr on it and I believe I could shoot it off my chin if I wanted to.
