IMR 4895 and Heavies

[notagrendel]

Since I don't see anyone posting about IMR 4895, even though the 6mm ARC Facebook page with QL data shows promise, I might as well post some findings. I went out to the range to test a few loads with IMR 4895 for velocity, pressure, and function. Velocities are two-shot strings.

Gun: AR-15
Barrel: 18" Proof Research SS
Bolt: JP HP bolt
Muzzle Device: GA Recce 7
Magazine: ASC 6mm ARC 15-rd

Bullet: 108gr Berger Elite Hunter
Lengths: 2.265" (1.650" 3-24 comparator)
Case: *-* 6.5 Grendel once-fired
Lengths: 1.480" (1.185" B350 comparator)
Primer: CCI 450

             Velocity      ES
25.5gr   2337 fps     5 fps
26.0gr   2398 fps    13 fps
26.5gr   2444 fps     8 fps

Since temp. stability of IMR 4895 is in question overall, I will play with that down the road.
