Just picked up a Taurus RB 454 casull. made a order for some starline brass as I have read they are the best. Hornady 300gr XTP mag bullets, should have went with the 240gr xtp mag, but oh well. I have H110 powder to use. I hear guys use either small rife or small rifle mag primers to touch these off. I'm not recoil shy, I used to shoot a hot 45-70 300gr load out of my encore pistol.
