[QUOTE="engineer40, post: 1102603, member: 90399"] I did test different powder charges. The very first time I reloaded any rifle ammo, I did start at the lowest charge. They all went boom fine; which was my goal the first time. I then loaded some IMR4350 in .5 increments but I started just below mid charge weight, not at the very bottom. None of those loads were exceptional. Ranging 1.25 inches to probably 2.25 inches using 4 shot groups. But I was shooting in direct sunlight on a 90 degree day. I don't think my barrel ever had a chance to cool. I have 40 more rounds loaded right now to test at different powder weights using IMR4064 at .5 grain increments. I just paid for a membership at a local shooting range and I should have my range access information in the mail within a few days. This will help my testing because I'll be shooting from a shaded rest with a more solid bench. The biggest reason why I think it might be mainly a bullet seating depth issue right now is both of the factory ammo's that I've shot through the rifle used flat based bullets, which I've heard are less susceptible to seating depth throwing off accuracy than both of the higher BC, ogive, boat tail style bullets I've reloaded with. And so far, both cheap factory ammo's have shot more accurate than anything I've reloaded. I mean, I've "read and heard" so many things sometimes reloading seems like witchcraft. So my above assumptions may not be correct. [/QUOTE]
