[DH302]

Ok I need some help guys, new to heavy 223. 26 in 1-7 twist heavy varmint profile, .090 freebore. Question is I want to try 2000 mr , seating depth 2.540
.010 off lands, what charge do I start at? Forgot fully prepped LC 12 brass alliant says 23.8 at 2.550 coal , is this start or max

With a 1-7 twist I would stick with 80 grain bullets, have you tried 90s in that barrel?

i'd drop 2 grains from Alliant's charge and work up to find your max. then work on some actual data

Not yet, that's why was wondering if 23 was too high to start

Boone what's your freebore

Off the top of my head I couldn’t tell you. I’d have to go back to my notes. I loaded a the 85 grain bullet at the neck shoulder junction tossed it to my smith and told him I wanted the chamber set up for it.
