Absolute Hammer load data

Loaded up some 155gr Absolute Hammers today in my 7SS.
26" Proof CF Barrel
1:8tw
ADG brass
FGMM 210M
Jump .02"

Varget
51gr 2990fps Slight stiff bolt lift

H4350
59gr 3129fps (Stiff bolt lift)

Seems like there should be more speed here since the 155 (158.6gr) HH gets 3132fps with 58.5gr H4350 (stiff bolt)

Not sure what to try next, any suggestions? Prefer to stick with temp stable powders. Have H1000, H4350, Varget, 4831SC on hand.
Were you seeing consistent velocities with each charge? Have you tried the Lee Crimp die? We have gained a good bit of velocity by crimping on our 6.5 Creed. Anyone know if the primer trick for the 6.5 PRC might apply to the Sherman cases as well?

@WiscGunner ,
Just took a quick stroll through the AH Load Data tables. Maybe not your preferred powders, but:
7SS - 155 AH - RL26 - 3115, with a 20" bbl
280-close to same capacity
140 AH - RL 17 -& H 100V,33-3400
- H4350 - 1/4T FCD-3228
- H 100V - 3375
7SS - 131 AH - H 100V - 3230
143 AH - H 4350 - 3169
155 - RL 26 - 3170

This will give you some food for thought. If you haven't yet, crimping seems to give good results with Hammers.

Thank you everyone for the input. I had though the AH liked a faster powder but it appears I should go slower. Local store has 6.5 Staball and 100v, will give one of those a try I guess and see what happens.

I will try to order a Lee custom FCD when I get a chance to experiment more.

When you run out of case capacity ,with no pressure signs , then move to the next fastest powder until you hit pressure, and still have some remaining case capacity.

Sir, Does this block of data represent 10 shots at each of 5 incremented by 0.5 grains, that is; groups of 5?
 
Thought I would share this very soft recoiling load I put together for my daughter. It really is fun to shoot and has recoil similar to a .223, which is great for a kid.

I have searched through most of this and other forums. Does anyone have any data at all on the 7mm PRC with 172 AH. Looking for a starting point and powder recomendations.
Go to Hodgdon's website and use data for the 175. That should get you started. I'd also send Steve Davis and email asking which powder he would recommend for I'm sure you're not the only one loading the 7 PRC
