You bet. With my max load .45-70's at 52 gr. Reloader7 and a 325gr. FTX or Interlock, I can stand to shoot it about 3 times before I start flinching. With my Limbsaver, I shoot 40-50 at a time without issue. I like the slip-on because it doesn't mess with the stocks on my Hawken, and two H&R BC's which have the steel buttplate.
Also helps when shooting the big Great Plains conicals out of my .50 Muzzle loader, those bruise me. lol
