The mercury finally climbed near 40 degrees here today, so I was able to chronograph some of the IMR-7383 loads I have working on. I thought the data might be of interest to others using this powder. These loads appear safe in MY GUNS, your mileage may vary. In other words, please be careful with surplus powders.
7.62X54R M44 carbine
Bullet: Remington .310" 180gr RN jacketed
Velocity: 2270 f.p.s.
Velocity: 2308 f.p.s.
7.5X55mm K-31 Swiss
Case: NNY (from Prvi Partizan ammo)
Bullet: Military pulldown 150gr FMJ BT
Velocity: 2475 f.p.s.
Velocity: 2502 f.p.s.
All figures are an average of 10rds fired. Chronograph was 10ft from the muzzle.
Hope others find this useful/interesting.
Would appreciate comments, particularly on how this compares with your experiences with this powder.
If the weather holds, I may get to chrony some more loads later today, and of course I'll post the numbers.
