Thread: Help needed for 308 subsonic load

Tested at 100 yards to start with, and no tumbling.
I then resighted at 50 yards, given that lack of energy at muzzle is going to restrict the effective killing distance ( imo)

Top 2 are from a cold clean barrel, having sighted at 100. Adjusted scope and then fired the two touching lower shots, before pulling one to the right.

Remington mod 7 with 16 inch barrel plus dpt suppressor. 7.8 gn of trailboss pushing a 151 cast projectile as made by shooternz. Exit wound on 18mm mdf suggests it may be a bit of a meat waster

I use 7.5gr trailboss with the 308 casts. Pretty quiet. I sight in at 50 and generally only shoot out to that with them. Pretty good on goats. They drop pretty quick though. On my 18" barrel tikka they drop 3.5" at 50 yards. We clocked them at just below sound barrier with that load.

I could shoot out to 75yards with the 7mm(08) projectiles accurately in my old rifle using 7gr trailboss.
