I have about 600 rounds of brass cleaned, sized. primed with winchester mag primers, and the cases have been belled, so I'm already to start charging and loading. I'm using a 250 grain (.452) HP/XTP bullet by Hornady, ,, I have been using a 250 grain JHP Winchester factory and have been getting great accuracy, I can shoot within a 4" circle at 50 yards so u can see why I would like to get as close to the factory load as possible. I would stick to the factory loads except for the price.. It costs me almost $1.00 a shot with the winchester loads.. and I love to shoot so it gets quite costly. ,, re-loading should cut my cost by at least 1/2 that much.. I shooting a Taurus Raging Bull with a 6" barrell,, I purchased a load book from gander Mtn. BUT in the whole book it doesn't have any loads hardly for the 250 grain bullet,,so if any of u have any suggestions as to powder and loads I would be greatfull..
