I have been pulling my remaining hairs out trying to figure out how to get these 168 Gr ABLRs. I wanted to try to keep them seated long so I could fit more powder in but apparently these type of bullets want to be seated deep and they don’t have a large window in the seating depth department for when the accuracy comes and goes. My barrel also seems to like the lower speed nodes better as well.
I went out today and loaded up 63 Gr of RL23 and seated bullets starting at .110”-.140” off the rifling in .010” increments. The .110” off really shrunk the groups. Accuracy was right at .5” at 100 yards, ES was 6 and SD was 2.9. Averaged 3055 FPS. Pretty slow for this round but it is what it is. I will try it out on game and see how it does. I am going to load up 10 more and go shoot it at 400 yards and see how it does.
If your ABLRs arnt shooting well closer to the rifling, don’t be afraid to experiment with seating them deep.
Put my finger up to it just to show a comparison for size of the group.
I'm looking to run 177 with my 7 max, I'm curious, did you go with the standard 0.205 FB or did you have to get it throated for additional freebore for the 177's to not have to seat too deep? Thank you.
Thank you for the confirmation. That confirms my math on that. California and lead free hunting though so no Berger's for me, although that would be my top choice otherwise. Those hammers are expensive.
@ johnyee1 So I ran a batch of 168 mth from cutting edge bullets. The advantage I have is I am running my 7 max in a long action so I dont have to single feed. I ran a test batch with 4831sc and hit 2850 but I have now found rl26 and am going to try that should hit 3000 easy and I am seating .010 off and I still have plenty of room for more powder.
