Hit pressure at 37.0 gr of H4350 and had 2990 on the chrono.
Will likely back off a bit and shoot a group of 10 at 36.0 and 36.5 gr to see what groups best.
This is also through a chopped and threaded 18” barrel. I’m sure if it was factory length I could push into the 3100 range.
I’ve got an 18” as well and 37gr of h4350 goes 3050 in mine. Have a couple hundred rounds down the barrel so she’s well broke in. Daughter will hunt with that this year. Grabbed a tikka compact 243 that I’m debating on cutting at 18” for her to use next year so I can get my 22-250 back.
