/

Today’s Topic:

  1. Sound Signature Review 6.241 – Tuna Cans Blackfin XL 12-baffle and 9-baffle on the 300 BLK subsonic bolt-action rifle. The economy evaluations continue – we first evaluated this stepped cone design on the 5.56 M4. How does this type of baffle perform with much lower pressure? And as a .375 caliber silencer, does over-bore induce performance loss? And what about FRP? Technical discussion of last week’s double-header report. (00:06:21)
