Today the weather was kinda ugly so I decided to stay in and load some ammo.
Several years ago I bought 10,000 GI pulldown 175gn Sierra Matchkings. Back when you could find them for under .10 each... It did not take long to figure out these bullets would not hold MOA size groups past 600 or so yards. Too torn up from the machine pulling.
Today I decided to put them to good use in my 300 Whisper for subsonic plinking ammo. Using Lake City brass, Federal primers and AA1680 powder I loaded up about 3,000 rounds. It only took about two hours on my 1050.
This load will shoot minute of softball at 100-150 yards with a dot scope. Very quiet and soft recoiling. Very controllable in FA fire. Cant ask for much more when essentially shooting 45 ACP+P ammo.
