Transvaal,
Thanks for those links. I had read through Rons thread but hadnt seen yours yet.
I am aware of the importance of being able to adjust bullet velocity to help in regulation if its necessary. Unfortunately my hands are tied with local laws. However, there is a pretty decent bullet selection out there in that caliber. They range from 300 grains to 500 grains and maybe even heavier. Obviously the powder volume can be adjusted a little bit as well but so can the burn rate of the powder. I probably cant go any faster than what the developer used, but I could slow it down. *shrugs*
