I went to buy a chargemaster 1500 and instead came home with another THXP in 204 ruger. Now I have 2 THXP with Nikon BDCs. 204 and 22-250. I hate when that happens. What is a good reload data book for that cal. My sierra does not mention the 204 at all. I would like to achieve 3950 fps useing a 35 or 45 gr bullet. Thats if the 1-12 twist will be good for those. Thanks again all,Dan
