Anyone care to post up a load for 7mm Rem Mag. with 140gr. accubonds? Thanks.
the tighest group from my 7mag with out tuning the load was 65 grains of r22 with the 140 NAB. lit by F215M primers, in winchester brass. i have not tuned this load or played with the over all lenght but it shot a .956 out of a stock remington... heavy trigger pull and non-floated barrel.
The best I've shot was 67 gr RL 19. I am not sure about the velocity, but out of a 24" barrel I think it was 3120-3140. Shot about 0.7MOA out to 200m when we tested it.
I have two loads:
65.0g of IMR 4350
140g Accubond seated to touch the lands
groups with the bullets touching at 3250
64.5g of H-4350
Bullets seated to touch the lands
3200 fps bullets touching at 100 yards
Please don't change the brand of brass or primer in the above loads...groups go to crap if you do!
Rifles and of course lot# of powders do change, so I'd back off a grain and work up to these loads.
I'm still tweaking but as of now:
Fed 215M Primers
63.8 Gr. IMR 4350
140 Gr AB
.005 off lands
.5" @ 100 yds.
I've tried this combo several trips to the range and keep repeating. Gonna play with seating depth some today.
