Being sick of the news, and it being a good morning, I hied myself off to the Place of Happy Loud Noises to make holes in some targets. Mostly general practice, but while there wanted to try something.
Remember the Aguila Super Sniper Subsonic .22 ammo? If you're not familiar with it, it's a short .22 case holding a long 60-grain bullet loaded to subsonic velocity. It's a very 'iffy' ammo with most guns; the rifling pitch of a lot of barrels will not stabilize that long a projectile, and accuracy sucks. Some shoot it quite well; the only way to find out is to try it. The first 15-22 wouldn't shoot it well, so wanted to try it in this one. Results:
The top-left diamond is that ammo. Top-right is Federal Champion, bottom-left Champion, bottom-right some old Remington Golden Bullet. The Federal has shot well in almost everything I've ever tried it in; the exception is some .22 pistols, just not quite enough power to cycle the action. The newer Remington GB won't work worth a damn in this 15-22(just fine in everything else, including the conversion for my .45), but this older stuff did. I was really surprised at that group from the Aguila; that's eleven rounds at thirty yards. Not the most steady of rests*; next time I can get to the outdoor range with a bench and rests I'll see what it does at 50 yards. I've read of some guns giving very tight groups at 25, then opening up a lot at 50; we'll see how this one does.
*I was trying a lot harder on this one to keep everything right, which may explain the wider groups with the Federal. The tall rings really help with the scope on this rifle.
