Well, I loaded 3 each of 72, 73, 74 and 75 grains with the intent to shoot them over the chronograph and for groups @ 200 Yds this evening. Those plans went awry when I couldn't hit the paper at 200 Yds.:mad:
Moving back to 100 Yds, the gun was shooting high and right. After adjusting for the change, I only had 2 of the 75g. rounds left. At 200 Yds, they shot 3/4" c-c. The light was fading fast as well, so the only useable readings that I got off of the chronograph mimicked what the rounds shot yesterday.
I'll do more loading tonight, for shooting tomorrow.
BB or others: What is the difference between the Federal 210 and GM210M primers? I have the GM215M primers as well, but I'm thinking now that the Magnum primer might raise the pressure on the hotter loads that didn't exhibit any pressure signs with the 210's. Are the GM210M's really any more consistent than the plain 210's?
I did pick up 9400 Winchester Large Rifle Primers (WLR) for a price that I couldn't turn down on Saturday. What loads would they be usable on? (besides .308's of course;)) The guy that I got them from used to shoot .308 Palma matches. There are a few boxes of Lapua D46 170 and 185g bullets as well, and a bunch of other stuff that I'm still sorting thru.
