28Nosler and 180ELDM

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.

Mine shoots great with 86.0 of rl33, .040 jump. 3185 fps, .5" or better groups.

257Tony at 86 of RL33, did you experience pressure signs?

Nope, I did start getting extractor marks at 88.0, that was giving me 3280 fps! 86.0 in my gun should be a good long term hunting load. I am loading longer than saami specs tho, 3.550".

Mine is set with the 180 Berger's at 3.522, that is .020 from the Lands, sounds like you have a longer throat than mine.
