I bought an sp-10 in the early 90s brand new. Bought a short rifle sighted barrel for it right away and have hunted with it ever since. Started with lead 4s and progressed to nitro heavy shot blends. Had a bad experience with them several years ago. I will leave it at that.
Started loading 2 1/2 ounces of 7.5 tss and got an Indian creek .690 for it a few years ago. Absolutely awesome gun. Pure killing machine. Several of my hunting buddies shoot the same gun and load and all are in absolute awe with it.
This season I added a sumtoy mount and a vortex venom. Wow, this is a game changer.
