I wrote about here. While I was out I took the opportunity to try these at 50 yards. Being as how I had already put the chronograph up and did not want to dig it and the tripod back out I have no velocity numbers, so that'll have to come later.
The first batch had the same 5.0 grains of 2400 I tried before:
The top two are the first sight adjustment(had to raise the rear a fair amount), the others were all fired at the same setting. I don't know if the two off to the right are from me or the load, or possibly from a gust of wind: with a projectile this light and velocity this presumably low, I don't think it wouldn't take much to drift them off.
I had ten of those loads, and I'd loaded five with 6.0 grains:
Those grouped tighter, but this isn't enough testing to decide if this load is better(more testing needed, damn...) With the extra grain there was still zero recoil, as in the rifle didn't shift at all.
For small game or varmints, I think this would do a pretty good job out to maybe 50 yards(need to get some more water jugs to try), and, as mentioned before, if you wanted to introduce the kids to a 'big' gun with low noise and recoil, these would make very nice loads.
Let's see, try them in .30-06, .308... I wonder if they'd work in 7.62x54r or .303?
