I use a few in .32, be it acp, S&W, Colt ...dont matter its pretty universal. When I get some , Im gonna try 7.62X38r through it, as I shoot those other calibers through my '95 Nagant pistol, and other small .32's I collect.
Makes for a good survival type rifle, or at least multi use. Good to about 75 yards through my '91, and ony about 40 through my M-39, and then they keyhole. Just gotta be close.
VERY Quiet with .32S&W, like "Poof!" insteda BANG!
Great for Bunnies in the willows, and load em single shot, I carry 4 (Thats all I got ~~LOL!!~~~) 'cause reloading is on the slow side.
I also use the 300 yard on the rear sight to hit at 50 yards POA, imposed with a 6'o'clock hold.
Great way to burn up Blazer aluminum cases, that stick stick stick to my chambers when its cold out and its the first shot. Brass for below zero for pistol cases, if you can.
