I purchased a suppressor for my Remington 700 /w 16" treaded barrel in 300 blackout. Still probably 5 -6 months away from actually being able to take possession of it. Anyway loaded up my first try at subsonic and chronographed them yesterday. The two loads were: 1. 194 gr Lehigh Max X, CCI-450, Starline unfired brass and 9.6 grs W296. 2. 190 gr. Hornady Sub-X, CCI450, Starline unfired brass and 9.6 grs W296. The powder charges were the loads listed on the Hodgdon Website. The 9.6 gr. charge weight of W296 was the only charge weight listed ( ie. no starting charge weight). Both loads produced in the neighborhood of 1190 FPS. It is my understanding you've got to get below 1100 fps to really be subsonic. I've read in multiple places the admonition about reducing W296 below recommendations. The only way to get these loads below 1100 fps that I see is to reduce the powder charge. Doesn't seem like a prudent idea. So I'm asking advice from experienced subsonic reloaders? I also have some Lil'Gun if anyone has ever used that. What are other powder recommendations?
