Because of the neighbors near my rural house, I shoot my heavy stuff at a range just over an hour away. I make it once a month.
I am in the process of building a back yard range for Colibri and Super Colibri ammo. My son and I have already shot a 500/pk and I just got in 4 more. It is fun, convenient, and relatively cheap. I have compared to CCI quiet ammo but the Super and regular Colibri are noticeably quieter. I shoot the super in rifles and regular in pistols/revolvers. Of course, semi-automatics have to be cycled manually. From about 150 feet away, the report and a sharp hand clap sound about the same.
I am using paper targets and .22 swinging targets, both commercial and home made.
I have been enjoying it so much I just bought a Henry for the range. I've also been shooting a Remington 512T, a Polish (Wz-48 military trainer), and a Nylon 66. I should be getting my Stevens Favorite soon from a local restorer. He is also working on my Hoban.
Handguns include a Ruger Bearcat and Mark I.
The ammo is not super accurate but quite fun. It is sometimes difficult to feed (Ruger Mark 1 mostly) and will occasionally stick in the barrel of my Wz-48 so I ensure that every shot leaves the barrel. If the shot seems too quiet, I visually inspect the barrel. Had one stick out of 100 yesterday.
