Here comes some load data from Sweden. Powders are almost excusive Vihtavuori, brass is Lapua and Hornady. They have similar case volume (hornady is 0.1-0.2 grain larger), I see no reason they cant be mingled.
Primer: Mostly CCI 400. Had some Remington 6½ BR, they tend to give 30-50 FPS more velocity depending on load.
Hornady SST 123 grain
COAL 57.5mm
Primer: CCI 400
Powder: N133, 26.0 Grain
Precision: 0.7-1" at 100 meters
Velocity at barrel: 739msec / 2425 fps avrage over 5 shots with SD of 2 msec.
Nosler BT 120 grain
Coal: 57.8mm
Primer: CCI 400
Powder: N133, 26.0 grain
Precision: Great, had 5 shots on 0.5" at 100 meters but most avrage around 1". Have not had favorable conditions (windy). But performs good, 3 shots will generaly touch.
Velocity: 777 msec / 2549 over 5 shots SD 4msec
Nosler Partition 140 grain
COAL: 58.5 mm
Primer: CCI 400
Powder: N540 28.0 grain
Velocity: 738 msec / 2421 fps
Precision: good, sub moa.
Used on Deer (Roe buck), shot at around 50m, passthrough with exit wound around 6cm. Little meat damage, so a great velocity for small (to be eaten) animals on ranges under 200 meters.
Woodleigh 160 grain Roundnose
COAL: 56.5mm
Primer: Remington 6½ BR
Powder: N540, 26.0 gr
Precision: 3 shots touched, 100 meters. Reliable groups.
Velocity: 655 mps / 2149 fps
V-max 95
COAL: 56.3mm
Primer: Rem 6½ BR
Powder: N133 28.5 grain
Precision: Sub moa, had one 0.5" and some larger. mostly wind. Can probably do better
Velocity: 840 mps / 2756 fps. This i think i can get to 2800-2850 FPS with no problem.
Esp. if use N530.
Hornady ELD-M 140
Coal: 57.5mm
Primer: Rem 6½ BR
Powder: N135, 23.5 grain
Velocity: 625 mps / 2051 fps
Precision: Best performing bullet/load i have for ranges 100-200. 5 x 5 shot groups avraged 17mm! (13-19). single groups now and then do 0.25 MOA, but thats as much luck for me. to much drop at 500m to be used (tried to), 250-290 cm drop or more, lacked adjustment in turret to make use of it.
