Benchmark

I had a chance to try a new powder today before is got too dark for the chrongrapah.

Load Data: (standard disclaimer as with any wild-cat, use at own risk and work up slow)

100 gr Speer SPBT (16 inch 1:10 twist barrel) seated to 2.255 COL. (16 inch 1:10 twist barrel)
Charge Hodgdon Benchmark
wt.(g)末没el. (fps)
23.8末末2364
24.5末末2411
25.1末末2494 small velocity deviation +/- 5 fps for 3 shot string
25.5末末2518 small velocity deviation +/- 2 fps for 3 shot string

Benchmark does not necessarily give the maximum velocities, but the velocity increase with charge increase is very well correlated with this powder.

I have some problems with a stuck case in my resizing die. Got a stuck case removal kit on the way from CH4D.

Anyhow I did have 30 rounds loaded up. Took it to the range today.

Load was 26.0 grs H335, Remington cases, CCI 400 small rifle primers with a 90 gr Sierra Game Point.

Used a few rounds to get the gun sighted in and fired 7 shots over a buddy's Chrony Alpha ans the sun was starting to set.

Speeds were 2606, 2604, 2594, 2589, 2579, 2606, and 2570. The online SD Calculator I used says that's a SD of 14 FPS.

5 shot group at 100 yards was about 1 1/2" with 3 shots touching and another 2 shots touching about an inch and a half away. I only loaded 3 shots in the mag and then decided to shoot a 5 shot group and loaded 2 more shots before looking through the scope, so I don't know if my movement caused me to shoot 2 separate groups or if that's what the group is.

Gun functioned just fine with the gas port as 320pf shipped it. I even put it on a different lower with an A2 stock and shot a few rounds and they functioned fine as well.


When I get the stuck case out I'll play with it some more.

I do have 100 prepped cases so I should be able to load up some more even if I have to send the dies back to CH4D.
