My computer is 300 miles away, so I don't have access to ql.
I'm working with the 357ar, based on 223 brass blown out and trimmed to 1.605". The pressures are higher than 357 max by quite a bit, 55k max.
Here's what I'm working with.
32.8 grs water capacity. Hornady 180 gr xtp. C.o.l. 1.95". The barrel is a 16" .358 bore, 1 in 14 twist.
Powder is H110. Bullet not engaging the rifling.
I'm looking for charge levels at 40k psi and 55k psi.
Thanks in advance.
