I never hear anyone talk about them, but I have used Winchester standard velocity sabot slugs with excellent results in my fully rifled 870. Accurate and will go through a deer at 100 yards. I would think that they would cleanly harvest a deer out to 120 yards, I just don't ever get a shot that far. I have shot at game or targets more than 150 times over 15 years and never had an issue with accuracy or effectiveness.
