I’ve done some of these with Unique propellant before, but this is some tries with Green Dot.
Anyway, first up was another try with a cat-sneeze* load, in this case the .30-30, 100-grain semi-wadcutter sized to .310”, over 4.0 grains of Green Dot, out of a Model 94 carbine. I was going to get velocity, but between the wind and the range being busier than expected, that'll have to wait. All groups shot at 50 yards from a bench.
First shot was a way low flyer, then these four.
Second set was over 5.0 grains
Then tried something new: also Green Dot, but using the same 150-grain flat-nose bullet, with a gas check, used in full-power loads. These are noticeably stronger than other light loads, the Lyman manual indicating around 1400fps for this bullet over 8.0 of Green Dot:
Upping that to 8.5 grains, not as good:
In the continuing trial of messing with that .45-70 when possible, these are a couple of light loads: 255-grain semi-wadcutter, intended for .45 Colt. These things come out of the mold right at .452", which is undersize for .45-70(nominal .457"). So, again, these got a three-wrap paper patch of onionskin, when dry were wiped on the side with a touch of bullet lube and then pushed through a .459" sizing die. First batch was loaded over 9.0 grains of Green Dot
Second was the same bullet over 10.0 grains:
Either I was steadier, or this rifle like the 10.0 grain load better. Recoil is there, but out of a ten-pound rifle it's just a bump.
I had a couple more of these, so tried them at 100 yards; using the 100-yard setting for full-power, they had the same point of impact in elevation, and a bit to the left(possibly from the wind), about 3" apart. Looks like this may well be the plinking load for that thing.
I shall now refill my glass of tea, and sit for a bit.
*Lot nicer sounding than 'mouse-fart', isn't it?
