Hey Guys, Just picked up a rebarreled .223 for MR F-T/R, and I'm starting load dev again. Rifle has a 28" HV Bartlein with the ISSF/.169 chamber. I plan to run 90gr VLDs, 90gr SMKs, or 88gr ELD-Ms behind Lapua brass and CCI primers. I've got ~75+ lbs of Varget, and I know that's 'the powder', along with 4895 (which I have none of, and can't seem to find a consistent supply). I'm hopeful to find a good load with Varget, however I never could get it to work to my satisfaction in my last .223 setup for TR. That brought me to looking at Vhit powders; they seem to have a very consistent supply here in the states, but I don't know many folks using it (I assume because it's historically been expensive). That said, I've done some searching and it looks like N140 and N150 would both work; the VV load data seems to show them both pushing 90s at near identical velocities. My preference would be to grab N150 as I think it'd also be a good option for 200gr bullets in a .308 too, however my main focus is to get something ideal for .223s with 90s. Anyone have any thoughts/experience/recommendations with either N140/N150 behind a 90gr class bullet in a .223? Any general ideas on expected velocities? The load data for the long throated 90/223 always seems to be off by a few gr/few hundred FPS. Thanks in advance! Mike Edit: Not interested in the double based N5x series.
