its working the case mouth back and forth that screws up the brass. i tried 223, not an amateur at forming since I make 577/450 martini from 24ga. But never could get any usable brass out of 223. Wish they made something like the 45 basic brass for 32-20 where you could just cut them longer. Shell h...

I use titegroup in my 44 mag subsonic, found data for mag and 44 special using it. Just found a load hotter than special, lighter than mag.

I use a 290gr cast in my 44mag, titegroup powder. Work great.

I tried the various recipes on the internet for subsonic 223. Trailboss, titegroup, bullseye. They all gave garbage results. Wide spreads in velocity, often 200fps. One might be fine, the next barely makes it out of the barrel. The trick I found was drilling the flash holes, not needed on 308 or 30-...

I quit using trailboss for this purpose. Worked, somewhat, just a wide spread on velocity. Really wide with a 223. Drilled out the flash holes and use solo1000 since I have a pile of it. No first shot weirdness, very low spread on velocity. Use a 200gr lyman powder coated, or 80gr in a 223.

I have a Lyman 147gr 9mm mold and a NOE 158gr 357 mold. The 147gr works fine in pretty much everything, powder coat them, shoot them thru various pistols and rifles. Had to try different powders to find a load that would keep it subsonic in a 16in barrel AND cycle. Was using them in a Keltech Sub200...
