Since the original load of 58gr of IMR4895 shot a 1” group, I tried working up the powder charge to see if it would do any better. I kept everything the same but used 58.3gr, 58.6gr, and 58.9gr of IMR4895.


The max load of IMR4895 looks very similar to the max load of IMR4064 from a couple weeks ago.
