Well Known Nuisance
Thank you very much for the info. Keep at it. Im sure you can figure it out.Today's testing: 123gr tipped, Midway seconds (they look exactly like Hornady 123gr SST bullets but with some tarnish on them) (sold out in 1 day). Goal: accurate, fast for the 7.62x39, hunting load if I decide to try it hog hunting.
Used AA1680 and AA2200. 100yd 5 shot groups.
1680: Didn't measure the groups, just eye balled them. Groups ~ 1.75" - 2.25". Eh, so-so.
2200: Now we're talking! 28.5gr 1.4". 29gr 1.29". 29.5gr 1.32" with 4 of the shots at .87". 30gr 1.53". I liked the looks of the 29.5gr group so let's chronograph 3 shots of that. No signs of high pressure. All loads of 2200 compressed the powder. Per data from NRA, Internet, and published data, it should give around 2400fps. Duh, they gave average of 2024fps at 6-7' from the chronograph. I wanted 2300-2400fps for the most power. FAIL my velocity criteria. My Blackout loads go much faster than that in the same bbl length.
Guess I try other powder(s). Or, just go back to plinking with the rifle and be happy with the fun it provides me.
CFE BLACK?? This is what I bought to try. Supposed to be good.
