Some info that may help.... Looking for advice on where to go from here. This is where I get lost. Powder type? Bullet Depth? Powder Grain change? Etc? Need some help on what to do next to tighten this group up. Clean Bore. Been bore scoped by pro Barrel only has 38 rounds through it. 300 RUM 1/10 twist 26” Proof Barrel Defiance GA Hunter Action. MCMillian Stock Trigger Tech set at 1.5lbs 208 ELDM 215M Primer Reloaded 33 Powder Nosler Custom brass Loaded round 339 at neck Redding FL 337 Bushing 3.091 at Ogive .003 off lands 96g Reloader 33 looked like I was shooting a scatter gun. Horrible. Don’t see how 1 Grain of powder made that big of difference. 95g instantly shrunk to about an inch group. 94.5g was a about same. No change. So based off this pic, I’m not sure what to do next or where to go with seating or charge and so on. I’m basically at mag length too. That’s a 5 shot group.
