|Tried these in my 590A1. Cycled fine, no FTF issues, etc.
Remarkably little felt recoil, Less than a .22LR. Fired at an old washtub that had been laying outside for a while, and the slug penetrated the washtub (it was corroded). Recovered the slug, which is a very dense rubber compound.
Am going to try the rubber buckshot rounds next to compare.|
