[QUOTE="4mesh063, post: 31120, member: 941"] Justin, For H1K or R25 Just add about 4% to 6% onto the loads you have for H4831SC and you'll be in the ball park. You will probably be able to move up from there but try it first. One shot at a time. These extruded powders are not much different than the parent powders. (They are actually the very same powder with different extrusion sizes, or, in the case of R25, A different coating). In any case, going slower with these 2 you'll be fine if you're using R22 or H4831SC as a guide. Don't even bother with Retumbo or MRP II then because you'll see a marked dropoff in velocity. I think the Retumbo could be nice stuff if you have a case big enough but for an 06, forget it. [/QUOTE]
