Your welcome!
Me either if it was 4.5 Grs.Me not get.
I was weighing every charge because I wasn’t confident in the metering consistency yet.
after 20ish rounds with no issues, I got a pop instead of a bang in my CZ75.
The most notable thing I saw with my .45ACP W244 loads was bullet seat depth with the same charge. When seated at max OAL, the velocity varied by as much as 50fps, with poor accuracy to boot. As soon as I seated the bullet deeper, things tightened up nicely... so I think W244 is very sensitive to case fill. I can't imagine there's a lot of space left in that 9mm case... but I would seat it a wee bit deeper and see.
@Charlie98 What OAL worked best for your loads?
I liken it more akin to WST than W231. Following the Hodgdon recommendations to the letter on this one, my first 200gr. LRN .45ACP loads (Saeco #45265), clear wax lubed, all went bang and hit the paper at 25yds. I call that good enough but it wasn't any cleaner that WST or any more accurate either. I'd be kind of disappointed but I got it from the shooting range for $25/lb and they didn't charge me for the range use that day. I think WST is a little better, to be honest.I assume W231ish type powder? I will consult published data but was curious if anyone has found it particularly good for something.
Using the RMR 200grn PSWC, 6.0grn W244 gave me 810fps, seated at 1.23" (out of a 4" barrel.) That same combo, seated long, at 1.245", gave me velocity readings from 750-810fps, and very poor accuracy, compared to the shorter OAL. Hodgdon data shows a cast SWC bullet, seated at 1.225", with 5.8grn W244 as max, but I wasn't comfortable seating the RMR bullet that deep... so my charges are over book, having worked my way up from 5.4grn W244. I don't normally load SWC bullets in the .45ACP, but I was stuck with them.
The Speer TMJ/RN 230grn bullet, with 5.6grn W244, seated out at 1.26", gave me 780fps and very good accuracy. That is long, compared to the very limited Hodgdon data, but besides the lower velocity, is an excellent load for me. I may, eventually, diddle with a shorter OAL, or bump the charge to see if I can get it over 800fps, but it's not a priority.
Thank you. I am just starting to use W244 and there doesn’t seem to be much data out there. This thread has the most info in one place that I’ve found.
I’ve got some coated cast 200gr SWC and RN to try and your data will go a long way.
