Well, it turns out that This one likes RL-22 more than it does 7828. I was able to get a group this morning around the 1" mark with RL-22 and some 140 BT. I don't now how fast they were going, but I'm guessing around 3250. I think I can tweak the COAL a bit and get it to do close to .5". We'll see. I still have two loads with H1000 that I want to try tomorrow. I might load up the 72 gr RL-22 load again tonight and shoot it again as well.
One thing I have noticed about both the M70 and the Mark V is I seem to get a lot of groups that go two and one, but the one is sometimes up to 4" out while the two are dange near cutting. Is this because of the free bore? Is it common in weatherby chambers? It doesn't seem to matter what Powder I'm using either.
Whats your thoughts?
