I’m working with the long range accubonds right now. I would love to use the TLR accent if they made some heavier billets for the 7mm.

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.

Did you ever get the 177’s to shoot well? I have RL23 & RL26! I was thinking you’d get better results with the RL-23.

I should have my 7mm max Sherman here in the next few days I was gonna start with the Berger 175 elite hunters and RL23!

I was at a shop yesterday that had 4lbs of n570 powder seems like it’s the king of spend but there are more accurate powders out there, so I passed on it.
