To me, the lt powders seem to be pretty forgiving in the heat but it's hard to beat a well tuned 133 load/rifle. I still have not shot the lt30 in a ppc. I bet you can get it tuned up. You might try blending it with lt32, also.Thanks Bart. I just acquired 3Lbs of LT-30 and Have a fairly new 1:14" ABC Barrel Chambered in 6PPC. I worked up loads with LT-32 and N133 for a 65gr flat base. The 133 shoots a tad more consistent than the LT-32 in this barrel. I am going to give LT-30 a fair try this week (In the Heat) and see how it performs.
