If I were you, I would try IMR 4895. Since it is slightly slower than the Hodgdon version, use the H4895 data and work up a load. I think you will be pleasantly surprised. Good shooting...JamesI read a lot about h4895, varget, and rl15 for the 6bra. There are several powders between these that no one ever mentions even trying. IMR4895 has one powder between it and H4895 but I can’t find any info for the imr with 103’s. I’m currently testing n135 and n140. Then I will try RL15 but it burns pretty dirty. I’m very tempted to try the imr4895 since I have about 12lbs of it and no H4895. As you can tell, I’m brand new to this. Thanks in advance
