Just a follow up here. Not done with load development by any means, but after purchasing 3 new 1lb jugs of H-50BMG and loading 210 Bergers to ~ .010 off the lands (gives me about a 3.87 COL--nice to have the 4" Wyatts box), I found that I was consistently getting 1" (2 shot groups, albeit-just working up to pressure signs this first time with the 210s) or smaller groups at 200yds in a bit of wind. One group went .25 or .3 MOA at 200yds. Mind you this barrel has about 1200 rds through it at this point. Still seems fairly accurate.
I bought the new powder because I had the impression that a 4-5 year old jug I had was significantly slower and wanted to use new jugs from the same lot. I watched the owner of Kesselring's take these jugs out of a brand new box holding 1 lb. jugs.
98-102g seems to be the most consistent area to work closer with.
Not sure on speed as it was raining and the range I was at doesn't allow you to use your own chrono and theirs was not working.
Case is pretty full, but with this bullet seated out as far as it is (boat tail/bearing surface junction just a bit below the neck/shoulder case junction), and a little tapping on the case to settle the powder, I didn't get any 'crunching' at all until 104g. Just an fyi.
Pressure signs (cratered primer only--dont' think I ever saw (even at 106g) ejector pin marks) with primers starting to crater a bit at around 100g or so.
