Yes, I am a Baptist, and yes I carry a gun. You might think I carry a gun because I don't trust God. Well you would be wrong. I have complete faith in my Lord. It is mankind I have no trust in

Re: Light Weight subsonic Single Shot Loads
I've managed to work up a new load using Hornady 150 grain FMJ-BT bulk bullets that is just subsonic, and seems to hold a very good group while doing it. Also when fired, from my Remington 700 16.5 inch barrel with a 30 Harvester suppressor it is about Hollywood silent.
Bullet: Hornady 150 Grain FMJ-BT 3037
Case: Converted Lake City Brass
Case Length: 1.362 inches
Powder: IMR 700-X 4 .9 grains
Over All Length: 2.062 inches.
Muzzle velocity: 1110 Fps

Re: Light Weight subsonic Single Shot Loads
My Favorite sub load for my Handi Rifle is the 90 grain Hornady XTP's, CCI SM Rifle primer and 4.5 grains of trail Boss 1.739 COL. This is so accurate and cheap to load, nit to mention DEADLY on critters...
