These were also exceptionally dirty rounds, stinky too, after 25 rounds of SC, it's a good idea to 'Boresnake' your barrel to remove primer powder and lead buildupĪccuracy from 35 feet was poor, not one hit The bullet from the SC would penetrate both sides of the Propel bottle, and bounce off the tree trunk, i retrieved one bullet from behind the bottle, it was badly shredded, and looked like it had been cut in half lengthwise by the bottle, but the overall bullet-shape was retained This was the quietest ammo of the bunch by far, the sound of the hammer striking the transfer bar, and the sound of the bullet striking the target were louder, I was shooting the SC rounds and the birds were happily feeding from the birdfeeder no less than 10 feet from me, the horses never whinnied in protest, this ammo could easily be used in an indoor shooting range with no hearing protection, and without the person in the next room even knowing you're shooting, however, accuracy beyond 20 feet was horrible, unacceptably large groups, this is an unpredictable ammo, as you never know where the bullet will end up, 4+ inch groupings were common, far too unacceptable for anything except close-range use Individual observations about each ammo type 22 Short, CCI CB-Long, Remington Subsonic (the last round in the pic is a standard Federal for scale, it was not shot)įrom quietist to loudest (on a scale of 1-10, 1 being ambient noise, 10 being a standard.

20 feet away, the other about 35Īmmo tested Flobert Rundkugelin Ball-Breech caps (there's an acorn on the brass, so I'll call these 'Acorns'), Aguilla Super Colbri primer-caps (SC), CCI. The target backstop was a large maple tree, the target, a Propel Fitness Water bottle weighted down with a couple of small stones to simulate a chipmunk-sized target, I shot from two distances, standing, seated, and prone, one was approx. It turns out my little shootin' match was a rather good test of both features of the ammo, we have some birdfeeders next to the house, and my sister's horses down the road a bit, still on our property though, I could gauge the loudness of the ammo by how it affected the yellow finches, chickadees and the horses. 22's to see which one is the best compromise between quietness and accuracy, generally, as one rises, the other drops, the more accurate rounds are *generally* louder, quiet rounds are all over the place, but they're quiet. 22, I have the ability to reliably run low-velocity quiet. Now that I have my awesome little NEF Sportster single-shot single-action.
