160 Accubond in a 7RM Load Data

[The_Whitetail_kid]

Hello everyone. I've started doing a little load development with the 160 AccuBond in my Christensen Arms Ridgeline 7RM with a 26 in barrel. First powder I started with, IMR 4831, I was getting very good groups with, but I wasn't getting the speeds I was after. I think I am getting about 2960 with it and am close to max load. What powders do most of y'all use for this combo? I'm hoping to push it in the 3050+ range.
I would like to me able to make this happen with one of the powders I currently have which are Retumbo, H1000, H4350, H4831SC, IMR 4831, and IMR 4350.

I've loaded for the same gun with h1000 and had very good accuracy and single digit sds..id have to check my notes for speed

Do you recall around how many grains you were using and seating depth?

I also load for that same rifle with H-1000. I first loaded the Berger 168 VLD and settled on 70 grains of H-1000 at a velocity of 3035. Very accurate and low es and sd. I later switched to the 143 Hammer Hunter and H-1000 also worked great with that bullet. I would give it a try should work very well. Happy shooting, Jason

28in Brux, Nosler brass, 160AB, fed215M, seated .030 off lands, 3125fps. ES 4fps 73gr H1000 ( this is over Lyman book max, Propellant profiles load book goes to 75gr and thats a bit much) shoots .368@ 200yd. Ive loaded for 4 different 7mmRM's all were over 71gr with the AB bullet YMMV........

Ok looks like it's h1000 or retumbo.

How far do these Accubonds like to be seated off the lands?

 

[bpcrshooter]

So far, of the 4 Ive loaded for, 3 are .030 and one is .020
