Dt219 Wrote:Lilja barrel with under 200 rounds down the pipe cant group any heavy bullets. 120 eldm, 123 smk, or hornady black 123 eldm. Bought the barrel new to zip the light bullets and it does with ease both 85gr Sierras and the 90gr tnt bullets across different powders and charges its almost like it cant shoot a bad group. So I thought hey let me see what the Grendel is all about. Picked up some 120s and already had the 123smk from a 260 rem. I had. Well long story short I have tried benchmark for the hell of it, varget and lever with the 120eld about a 1.5in is all I could muster from those powders. So I picked up some cfe223 this wknd and tried it with the 123smk. Same result about 1.5in groups. Tried the hornady blacks. Maybe 1.25in group. Try different pills or powder ? Its about to get old burning through stuff and combos that should group better than it is. Bumping shoulder back .004 full length hornady sizing and seating dies. CCI 450 primers, starline brass. Prob contacting Lilja in the morning.
Well did you try to work up a load based on what your barrel and chronograph told you it wanted or did you just pick a few charges ad one seat depth and go oh well it doesnt like 120 class weight bullets?
Not being a a@$ but your OP post doesnt tells us anything about what you tryed in the gun for a handload work up.
