Why a 220gr SMK? There are dozens of sub load threads here, try the search function.

Reny 700 20" with 1/11.25 twist

Winchester 1x Brass
CCI BR2's
Trailboss 10.5gr
180gr Hornady RN
OAL: 2.643
velocity = 1001 fps

what is your barrel twist? Most 308's can not shoot a 220 subsonic.

I've tried 220 Sierra RN's loaded backwards on a 16", 10-twist barrel with so-so results - about 2" groups at 100 yds.
They wobbled a bit going into the target - I would not shoot them with a suppressor

13.2 Trailboss
Fed 215 magnum LR primer
9/64" dia flash hole

1/8 twist
20" barrel
This will be for pigs through a GhillieBear suppressor.
Mainly at night.
