I have been using 37 1/2g of H335 and a Remington 125g psp in a bolt action .30-30 with very good results. It shoots flat enough to hit a coyote at 250 yards, and drops whitetails fast. My wife has been using this load for about 7 or 8 years now. It is traveling at 2630 fps, depending on the brass, some is a lot heavier than others. You might want to try the Speer 130g FN, Paco Kelly highly recommends it. I tend to use the 150g bullets most of the time. This year I finally tried the 170g bullet in my model 94, and I was not impressed at all. I shot a buck at 125 yards, through both lungs. He went off into the trees, and I had to finish the job 15 minutes later. He was bleeding out, but in my experience, the 150g bullet would have done enough damage to his lungs to have him dead a lot sooner.
