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.

You'd probably have to use 357max and adjust the case capacity and upper pressure levels. 357ar is a wildcat.

That's what I do. You can save it and add it to the list, but it disappeared on the last update and I haven't added it back in. From there I'll take the (magnetospeed) chronograph speed and adjust the water capacity to match the velocity. Figure there's no free lunch, but they're usually fairly close. Hard to read, but 19.9gr H110 comes in at 40K, and 21.9gr H110 comes in at 55K with a 32.8gr water capacity, 180grxtp at 1.950".

Thanks, guys. That was what I was looking for, Moleman. I posted here because of the traffic volume.
