I've only zeroed it at 100m but it is making 1 hole groups with the Hornady 120 AMAX loads and running about 2750fps. The 140 factory AMAX load goes 2550. I'm kinda done with long barrels.
Interesting.
Looking at some ballistics tables, the difference between your 18" barrel (140 @ 2550) and a more typical "long" barrel (140 @ 2950) is worth about 225 yards.
"Looking at some ballistics tables," eh? Wow, I wish I'd thought of doing that before now! I'll bet I could've saved myself four decades of actually shooting schidt to figure things out. TFF.
Edited to say... Rock on, Tennessee. Enjoy your new rig. Just don't consult ballistic tables as you might be disappointed.
