I haven't hand loaded for my .270 Win closing in on two decades. I have 2 boxes of 150 grain Partitions. I was going to go with 58 grains of H-4831. However, I've read that R-22 provides excellent accuracy & velocity. I have a few pounds of R-22. Has anyone loaded 270 Win with 150 grain Partitions using R-22?
I hope to get a 150 grain Partition dialed in for an upcoming elk hunt.
