After running through the chrono I shot 4 5 shot groups shot One(third one) was one hole and the others where around a inch no better groups where very eratic..
Think Ill load up several backing off by .2 grains down to 47 and see if things settle in.
RC, with the 168 grain Amaxes I loaded up 3, five round sets of 46.5, 47, 47.5 grains. The most accurate load was with the 47gr grain charge. The speed going from 47 grains to 47.5 was only about 20fps. I think that is do to the shorter barrel. The jump from 46.5 to 47 was like 60fps. I plan on working off to the 47grains up and down by one grain increments to see where the best accuracy is. I'm using new Winchester brass, and WLR primers. I haven't seen any pressure signs yet.
With the 175 grain Match Kings, I just loaded one five shot group. I used 46.5 grains with the same brass and primers. I got and average of 2770fps. This was a very accurate and I'm going to work off of up and down to see just how good I can get it. Hope this helps. I'm in the process of preping my brass again now so I can do some more research. As sone as I have some more info I'll post.
