I need some help with the poor accuracy of this bullet as others have reported that it groups well for them.
Bullet:
Lee 312-155-2r mold using wheel weights, powder coated with smokes powder. Sized to .309, LC brass and ginex primers. No gas check. OAL 2.010
Load: 5 shot group @ 50yrds
Shooters world blackout 17gr 4-3/4”
Shooters world socom 15.5 gr 5-1/2”
Socom 16gr 4-1/4”
Note: just to compare I show FMJBT with each load and hit 1-1/4” to 2” groups
I am using an AR 1/8 twist 10.5” barrel slugs at .308 using brown and sharp micrometer
Hammer test on the powder coat passed with great results.
Thanks for any help or ideas.
