Put together a Savage LA 6.5x284 with a Krieger 26" bbl, chambered by Krieger,1-8.5 twist , salt bath nitrided, bell and Carlson bedded stock (tang free floated) with decent 5-30 Frontier scope. Trigger about 2 lbs. For the load work up I've tried H4831sc , H4350, Win 760 , Retumbo ,RL 17. Bullets, Berger 140vld hunting, Berger 140 elite, Nosler 140 Cust Comps, 100 gr Barnes ttsx , and nosler 100gr ballistic tips. And loads ladder tested. Didn't do but 3 shot groups @100 , but still best accuracy is about 1 moa. I have even removed and re head spaced bbl. I have built other Savages that shoot 1/4 moa, and keep accuracy out to 500+ yds....(not that I am a great builder, but I know the procedure) I guess I'm looking to see if anyone has had a high quality barrel that they just couldn't get to shoot? I know that some will say try 120's or 130's or etc....but with the life expectancy of the cartridge, don't know if I want to keep chasing a ghost. Might just go new cartridge to ?????
