Updated. Sorry for the goof?Got some load info.
An earlier post of mine disappeared when this site had issues. So, I’ll recap it first. Tried Steve’s load with the 140 gr Absolute in my 280 AI using HV100. I hit pressure early, which I have now determined to be caused by 3x fired & annealed Nosler brass. Did a redo today with virgin Nosler brass and hit 3416 fps at 64.0 gr and no pressure signs. Looks like I have a nice node from 63.5-64.0 gr, so I’m going to fine tune it and not chase more velocity.
Last trip out, I also tested the 162 gr Absolute in my 30-06 with IMR4350. This powder was waaaaaay too slow. At 60.0 gr it was only 2969 fps, but accuracy was excellent.
So, decided to try a much faster powder today and went with Benchmark. I was real conservative and didn’t push it much. Started at 47.0 gr which yielded 2739 fps. Stopped at 52.5 gr at 3000 fps. Plenty of case capacity to go higher and absolutely no sign of pressure.
I’m using virgin Hornady brass, CCI250 primer and a COAL of 3.335”. I’ll report back once I get to try out higher charge weights, but Benchmark looks promising.
