Howdy All ---
Well, I just got my Ruger #1 rebarreled for 6BR with a 1:8 twist at 24" length. I proceeded to make up some moderate loads using 28.5gr of Varget and the Sierra 107gr, torched with a CCI450 in Lapua brass.
Much to my shock, these were all over the paper -- about a 6" radius at 100 yards. And with the signs of keyholing. Argh.
Is my situation,gun and ammo) recipe marginal for the 107gr MK ?? I have made up some more loads with 30.0 gr of Varget but have not shot them yet.
What say out there veterans of the 6BR and the 107gr MK ???
What is wrong?? Thanks --- Bob :,
