First actual ladder test day with Hammers. A fun and educational day.
M70 Classic Stainless in 7mm Rem Mag. 26 inch with 1 in 9.5 twist. 131 HH
I loaded rounds up through 78.0 grains but stopped at 76.0 since I had more velocity than I imagined, decent group, and nothing to prove.
I don't see those primer ridges as excessive, but feel like I'd be greedy to push it more.
Next session I will be playing with seating depths and crimps at 75.0 grains of RL-26
The time stamps puzzle me since I did walk downrange every 4 shots to mark the target and let my barrel cool.

What brass? Crimp if any, and OAL of cartridge, please

Federal Brass
COAL = 3.350" (.050" off the lands, plenty of room in the magazine box.)
I flare my case mouths a little so I don't damage the bullets during seating. The crimp is just enough to iron that out. Petals on the Factory Crimp Die still have about 1/32" gap in between. I don't feel any resistance in the crimping operation.

@gltaylor - I just read the article about marking my FCD in 1/8th turn increments. When I go shoot for groups I will post my crimp using that method.
Following Butterbean's method, when the die collet becomes finger tight around the case neck, there is still a visible space between the fingers of the collet. This is "zero mark" on the die. It may not feel like much, but it is still crimping a little. Proceed in increments til you find the "best" setting for smallest groups once you find your powder charge. JM2CW.

CVA SCOUT 45-70 rechambered
23 in w/ brake twist. Yes
250 SH
Bertram brass
COAL 2.955 .005 jump
1/2 FCD
WLR white box
Powder 5744
Start 63.0. 2842.
Stop 67.0 3030. No signs of pressure
1.5 moa @100
Rx7, IMR 4198 and AA 1680 we're also used and it was determined that 5744 produced the highest velocity. All groups were in the 1.25 to 1.5 range with all powders.
Extreme spreads suffered greatly with anything longer than a jump of 0.005
This load gives an ES of 16 and a SD of 8. I can live with that.

Turn about is fair play! Come on.... brass?, twist rate? 2 SD numbers?
You can do better

It’s almost the same as the GM205m. The cups are set back a little further from the anvil to prevent slam fires in gas guns. That’s what the AR at the end stands for. They work great.
