The H380 looks like a good stable load that should push it over 3700 but I'm worried that ill be packing too much powder in the case considering that long pill. H380 is tried and true sir. I would dispute the bullet before h380 haha.
I have some 4895 I was planning to try but after more research I think I'll try Varget and Benchmark. I'd like to work those long 53's up to 3800fps. Fingers crossed.
I'll try both of your suggestions if at all possible this weekend and post the results. Thanks again!
