the advice from MSHitman is good, stay with trapdoor load data if you hand load or any mainline factory ammo until you get used to it and then start working up if you think you want more power. I had a factory non ported barrel and an ssk ported and the porting made even my hot loads nice to shoot but the factory barrel with big 440gr's scooting along was miserable to shoot.

I won't be wronged. I won't be insulted. I won't be laid a-hand on. I don't do these things to other people, and I require the same from them. John Wayne-The Shootist
