So I finally bought into the 300blk game. Reloading supplies for 308 subsonic are tough to come by, namely Trailboss. I ended up picking up a savage pcs in 300blk with a 10.5 inch 1/8 barrel. Getting into 300blk I read on all kinds of data and settled on vv n120 for its quietness and cleanliness.
So my question is on the quietness part. Is a 16inch barrel more quiet than a 10.5 with suppressor on it? Factory ammo was ok but I assume it was gassed up for semi auto function. I loaded up some 190gr subx rounds 10.0-11.0, 11.0 being 1088fps avg. 10.8 at 1046, and the rest being less than 1000. 10.8 was my quietest to the ear but all seemed loud.
Maybe I’m spoiled with using trailboss with 308 subs, but so far not impressed with 300blk quietness even down to 900fps with n120. My trailboss load with the same bullet is half as loud easily. Using the same bullets and can. So is barrel length the issue or another powder better suited? My year long reading escapade told me n120 was the ticket outside of the undocumented bullseye and red dot loads I saw. Also being a bolt gun not concerned with function or bho, just accuracy and sound.
