Thread: .22 with subs, how short and what suppressor?

This is my set up bottom one is hmr 18” I think
.22 is 16” the dpt is shared between these two and my .233, I pulled the dpt apart the other day cos I was bored and there was not much fouling at all not sure on round count but it’s up there, I think 4 x 223 party packs(250 rnd packs) on the 5th slab of hmr and maybe 500rnds of cci subs
