So this is something I was supposed to have done much earlier this year, but I've been slowed down from a pretty heinous injury on one of our Boy Scouts activities back in May. Snapped my achilles tendon like tow strap giving out.
Anyway, I haven't been shooting much, so I finally got out today to do some reviews as promised.
I started with some ladders I had worked up earlier in the year.
123gr SST
Federal brass 1x fired 1.208" headspace to shoulder datum
Rem 7 1/2 SRP
Hodgdon's LEVERevolution
COL: 2.250"
Temp: 60˚F on range thermometer
Chrony Beta Master 15ft from muzzle
29.8 2453
30.1 2465
30.4 2499
30.7 2517
31.0 2534
31.3 2596
31.6 2608
31.9 2605
32.2 2658 (This averages 51,551psi in a SAAMI chamber.)
129gr SST
Lapua brass 1.215" headspace to datum
Rem 7 1/2 SRP
LEVERevolution
COL: 2.310"
60˚F
Left string was shot first, then the right one
29.3 2370 2407
29.6 2393 2400
29.9 2448 2405
30.2 2453 2404
30.5 2504 2453
30.8 Error 2475
31.1 2485 2512
31.4 2530 2523
31.7 2534 2545
32.0 2572 2572
31.2gr CFE / 123gr AMAX load
2599
2557
2582
2617
2617
2564
2586
2608
2619
2566
AVG: 2592fps. (AVG chamber pressure with this load is 46,235psi. in a SAAMI chamber.)
Hornady American Gunner 123gr BTHP

2456
2465
2463
2437
AVG: 2458fps
Everything fed fine from the mag even the 129gr SSTs at 2.310" COL. I think I would choose the 129gr SST load for hunting, didn't notice too much difference in recoil. Fun little rifle to shoot.
All my primers have nice little dimples in them. I didn't see anything crazy going on with the brass, not that I rely on brass as a sign of excessive pressure, but I definitely still look at it. Even the Federal brass looks good.
We'll see how it turns out after being run through the tumbler and de-primed.
