I was wondering if anyone out there has found a good powder and OAL combo in there 28N using 180ELDM? Yesterday was the first day I was able to test this new bullet, but was trying a new powder as well, IMR 8133, I found in my first intial run the best groups are at the Max charge of 81.5gr, now I plan to move it up a few grains and down a few grains to see if we have a better grouping. At 81.5 with three shot group at my 200yd zero, I had two measured 3/4" and the other was a flyer out inch horizontal. When testing this last three rounds, the shade was over my Chrono and it was only registering 2800 - 2900 FPS, which cannot be correct since the starting load of 75.5 was running the same speed. The OAL for these loads are sitting at .020 from the Lands. I would be interested in others experience with this cartridge and bullet combo, I have Retumbo, H1000, RL33 and IMR8133, I cannot find any VV570 anywhere.
