I started with 60.0 grns of H-4350, win. brass, WRLM primers, 180 grn NAB, I increased the load by 2/10 up to 61.2, (this is my first round) I still might try from 61.2 to 64 which is max. The book says 60 grn will be about 2799 FPS, 64 grn will be 2950 FPS, I divided that to where I figured that the powder will do an increase of about 37.75 FPS per every increase of a grn of powder. IN this round 60.6 and 60.8 gave me the best group, that is about where I want to be with FPS. Remember I was using N-550 and getting about 2817 FPS. The H-4350 looks good at those two loads, maybe better above 61.2 grns or should I work around 60.6 and 60.8. I am gonna try and post the pics of the targets, all are mark as to what they are and I also included three shots of N-550 and 150 grn and the .270, it did good today. I ready for some constructive critizism.
