Little bit of excitement today… After some research, actually a tone of research and cross-referencing and actually finding videos of guys shooting milsurps ammo through a chrono, 100’ish gr milsurp round should be travelling at around 1000fps +/-50fps.
Fiochi factory ammo claims 850fps, which is load of shit, it’s more like high 600s fps low 700s, with barely felt recoil, which is saying a lot for a feather weight M1895.
Last night I (did some loading) estimated around 3.6gr of Trail Boss as max charge. Given how I seat and where the max charge line is, I feel like there’s at least 0.5gr reserve. Anyway, passed the ‘shake’ test and tonight I gave it a go.
102gr cast bullet with 3.6gr of Trail boss gets me to mid-800fps range. No signs of pressure and cases fall out freely. Most excellent!
I don’t think half a grain of TB will get me across the line, which is expected, but I wanted to give it a go. At 15 yards it’s actually quite accurate for what it is and feels really good. Having the load process down, I just banged out a cylinder worth to run through the chrono. While there are no pressure signs, you certainly feel it and feels good, just the right level of recoil with TB.
Next, I will keep working with AP70N. I stoped on 2.8gr, just learning about the cartridge, next workup will be from 3gr to 4gr in various increments. I have a feeling, I will find the right velocity just shy of 4gr.
Part 3 I think this week.
