A few years back I had a custom 338 Edge built on a 700 by a reputable smith. The gun never shot very well. Usually right around 1 MOA. I tried just about every load I could think of with the 300 SMK but it never got better. After about 250 rounds, I sold it. I explained to the buyer the issues and he seemed not to care. Just before I sold it, I took it out for one more trial. It shot two three-shot clover leaf groups at 125 yards with loads of 91 and 92 grains of H-1000. I know the current owner and he is as pleased as can be with the gun. He claims 0.5 MOA to as far as he cares to shoot.
This got me thinking…and kicking myself for selling it. The bullets I had been firing were purchased with moly coating. I wanted nothing to do with the moly so at the recommendation of a few others, I tumbled it off. After looking at the cross section pictures of the 300 SMK that Shawn Carlock posted, I wonder if the cavity filled with tumbling media causing poor accuracy somehow? The two cloverleaf groups were with new bullets that had not been tumbled. I just chalked those groups up to a fluke.
Any thoughts on this?
Thanks.
