Savage Experts - Your assistance please
I have a Savage 223 that has me pulling my hair out.
The specs: savage action, ptg bolt and bolt head, precision nut and recoil lug, B and C medalist stock (bedded), Brux barrel 12 twist Rem varmint contour, warne bases, leupold mark 4 rings, SWFA 16x scope.
The problem: I can't get this thing to shoot consistently. I'm never had so many 4 in sub quarter MOA and 1 flier groups in my life. Of course sometimes it likes to mix it up by giving you a perfect 1/4 inch 5 shot followed by a 1 inch 3 in one hole with fliers on either side that open it up to an inch. There is no consistency to the fliers either. Sometimes its the first shot, sometimes the last. Sometimes they got right, or left, or up or down. You get the idea.
What I have done-
Floated tang and relieved stock so no trigger parts are touching.
Shot with barrel fully floated
Shot with a pad in front of the nut.
Different (known to be good) Shooter
Different scope, rings, bases
Different Barrel (started with a Mcgowen prefit)
Different Bolt head and bolt (factory)
Various Factory loads
All variations of reloads. Different brass (fed and rem, sized, trimmed, flash hole deburred, primer pockets uniforms. Different bullets (Hornady, Sierra, Berger, 52 and 53 match, 50 grain v-max, 55 ballistic tips, 55 grain BTHP, 64 grain gold dots) Different powders (varget, H332, BLC-2, 748. Different primers. Everything seating depth I can think of from jamming the lands to jumping forever and a day.
Shot off bags, shot off rests,
I've loaded for it on my press - rcbs, lee hand primer, harrel powder measure, redding dies, My buddy took a shot at loading for it. Similar loading setup but he also went to the added steps of weight sorting cases and neck turning.
Scope rings are not hitting the lug, scope base screws are not hitting the bolt or the barrel threads.
Everything we do, it shoots the same. I'm thinking I might try to redoing the bedding. I am also thinking about loosing in up head space a touch. I head spaced it tight (factory ammo will usually have a rub mark on the rear of the case from the ejector when the bolt is closed.) I can't see how this can be negatively affecting accuracy but I am running out of ideas here.
Any opinions or advice would be greatly appreciated
