Hello,
I just built my first .300 whisper. It's my fourth AR build. It has a 16" bbl from model 1 sales. The only load I've tried so far is with win 296 and 180GRN bullets. It really didn't work well. It wouldn't lock the bolt back, and I had one blown primer. I'm thinking the powder may be too fast with my gas port being in the carbine position, but I don't know.
Other factors may be the one piece gas ring I use in my guns. They some times take a little time to wear in and funtion properly. Also I hate the Spring noise on AR's so I added grease to the buffer assy.
Anyway, I'm glad I found this site and will be doing a lot of reading to try and figure this out.
I'd really like to find a load using powder I have on hand, especially W296 or maybe IMR 4831.
To make a short post long
HELLO
