[QUOTE="MagnumManiac, post: 900866, member: 10755"] It is completely feasible to reduce those groups by handloading, but it won't just happen magically, and neither will 'their' load unless it has been shot in your rifle and is a 'known load' for YOUR rifle. I would be checking the action screws to see if they're too tight or too loose, and also how much contact their is between the action and the stock/bedding material, fore end pressure, if any, and if there is any twisting in the stock, if synthetic, or swelling and twisting if wood. How heavy is the trigger pull? This could have an effect on your groups. Do you touch the rifle ANYWHERE with your non trigger tugging hand? This can effect your groups badly, some rifles are sensitive to changing grip pressure along the fore end, and are effected by shifting in the front rest, unless placed in EXACTLT the same position for each shot, the POI can shift significantly. This is fairly rare, but does happen. When you start loading for it, the very first thing you need to determine is the length of the throat, the actual number isn't important. First take a case and put 2 narrow slits opposite each other in the neck, a Dremel cut-off wheel works wonders, size the neck about half way down and place a bullet just into the neck andccarefully chamber it in your rifle, cock and uncock the bolt a few times, then carefully withdraw the bolt and case, then measure the OAL, take note of it for future reference and that is where the start of the rifling is for THAT bullet. Do the same with each bullet type you want to use, as each bullet type will have a different profile and therefore will be different distances from the rifling. Once established, you then seat the bullets the amount LESS from the OAL that was touching to give you the amount from the rifling, or amount of 'jump'. I'm sure others will chime in with anything I may have missed. Cheers. gun) [/QUOTE]
