I just loaded up a few test loads with 130gr NBTs and H4831 and 150gr NBTs and H4831. Now if I can just get a day when it's not 90 outside I'll go give them a try.
130gr started at 58gr and went up to 60gr in .5gr increments
150gr started at 54gr and went to 55.5gr in .5gr increments
Sounds like a winning plan to me. I really like VV N560 with 130's. I have obtained excellent accuracy with 55gr H4831SC and 150 NPT 210M combination.
My experience with the .270 only goes back 42 years, about 20 rifles and lots of game. I've hand loaded for the cartridge from the first one.
The classic powder for the .270 is H4831 (including H4831SC, which I prefer for it's better metering and density).
My favorite load is 60.5 gr/H4831SC, Federal 210M primer, 130 Nosler Partition, Nosler brass. It clocks an average of between 3025 and 3050 fps in my three rifles whose barrels are from 22" to 24". I seat to magazine length as it runs out before I hit the lands.
For 150 grain loads, I use 58 gr/H4831SC, Federal 210M primer, 150 grain Nosler Partition, Nosler brass. This averages just under 2850 fps.
GF1 were you really able to get to 58gr and a 150 NPT? I note Nosler max at 55gr. The hornady data does state 57.7. I would imagine there are batch to batch differences.
Good luck and shoot straight all.
