308 Bullet
First posting, anyone have a suggestion for sub-sonic 308 ammo out of a 16"bbl with 1:10 twist that won't tumble or keyhole? Don't car if it won't cycle a semi as I have a side charger attachment.
Re: 308 Bullet
1:10 is not great so be conservative. Jacketed bullets I probably wouldn't try much over 150 or 165 grains. 150 gr st 1000 fps still hotter than a 9mm pistol so no need to go crazy.
Flat base is better because it should be shorter overall than a boat tail of the same weight. Overall length is the real concern with stability, not the weight. Cast lead is great for this but it will lead up a sealed can. I played around a little bit with the 200 grain Lee in a 30-06 but I hated the crappy low quality 2 cavity molds Lee makes. Ended up building a 300 Blk with a 1:7 and abandoned the '06 project.
A pistol can will work for subsonic .308 and if it is a .45 can there is less chance of a strike. Cast bullets are fine for pistol cans.
If you're going to use a paper target to test for keyholing, you need to do it pretty close up to get truthful results. Your can does not care if a bullet is keyholing at 50 yards, but it is also possible for an unstable bullet to become more stable as it travels through the air.

my buddy uses Hornady 30 Cal .308 180gr Round Nose for his subs, very quiet and accurate in my bolt gun
