DocD .... I hear you about the cost of ammo. I hand load a lot as well and similar with components, though not as dramatic where I buy my reloading supplies. Fortunately about 5-6 years ago I sort of stocked up on primers, powder and bullets.

Back to the sabot stuff .... the guy that uses that Rem 870 droooed a nice buck with it at the far end of a food plot which we had ranged at 244 yards from the box blind. He had changed out the scope to a Nikon that has the drop compensating scopes.

sabot 100%... rifled slugs are intended really for smooth bore barrels however you wont really do any damage the other way. the sabots work great in rifled barels. i have a mossberg 20ga slug gun and the sabots are very accurate and have high velocitys.

DocD, I guess it doesn't surprise me that a rifled barrel improves the accuracy of a rifled slug. I'm curious what you found about range. I'd assume that even out of the rifled barrel, the rifled slug wouldn't keep up with the sabot.

As for the original question, you can do it, but if you spent the money on a rifled barrel, why not shoot the ammo it was designed to work with out of it? It's expensive, but after you figure out what slug your gun likes, you won't have to spend that kind of money every year -- just enough to get a little practice and confirm your still sited in.

I agree with everything you have posted, totally agree with "if you spend the money on a rifled barrel, why not shoot the ammo that best suits it!!" That is what I do!! It has been only the last few years I have come to shooting "Slugs" & have really enjoyed the experience. When I first started taking the slug guns to the range I experimented with finding the best slug for each gun, & your correct!! a person can burn up some shells (money) finding the one that works the best, while I was experimenting I tossed a few plain "Rifled slugs" down range, I was very surprised at how accurate they were, (coming out of a rifled barrel) Not as accurate as sabots but they did very well. & I really didn't experience much fouling, Slug technology has come a long way in the last few years. I will continue to hunt with the Sabot Slug, but, in a pinch would be very comfortable using Rifled slugs, I will be going to the range in the next few days & will take a few rifled slugs along, I will revisit the post & give a short report, jmop Doc

Shoot sabot slugs threw your rifled slug barrel... It's like shooting a patch and ball threw a inline muzzle loader... Sure you can do it... But your a jack wagon if you do...

Being from Illinois, we're slugs and ML's only. I have a couple friends who do shoot rifled slugs out of their 870 rifled barrels. It works for them, but where we hunt, most shots are under 50 yards. I always wonder how they'd do at a longer range.

you work hard for your money, you love hunting, spend alot of money on a gun, equipment, licenses/tags, gas, etc. then your thinking of going cheap on the ammo.....makes no sense. sabot slugs are like High Def TV, where as rifled slugs are like a TV with rabbit ears...........rifled slugs are good out of a smoothbore
