I have a J. D. Jones, SSK .300 Whisper upper with a can on a Colt lower with aftermarket trigger. It's way too heavy, IMO.

Shooting subsonic is a pain, as some loads want to pop (go supersonic). I find it hard to stay subsonic and still have an effective load. Just my opinion.

Right now, I'm going to load supersonic rounds with 110, 125, 130 and 150 gr. bullets, as I have a good supply from years of reloading. I also have plenty of H-110, Lil'Gun and 296 to make it work. My Dillon 550B is all set up, ready to go.

the weight is about right minus the can, so I'm not using it.
