It is not recommended to shoot in a rifled barrel.
If you have a shotgun with a rifled barrel, the manufacutrer would advise you to use the Trophy Copper slugs P152 TC.
I have shot 60+ rounds of rem accutip sabot and 100+ rounds of TruBall.
The biggest thing that is noticeable for me is @ 100yds. The accutips droped 5-6" (+/-) while the TruBall's were off the paper probably at 10". They weigh almost twice as much. So the drop almost 2x's more. One other scientific difference is that the higher velocity sabots do retain more energy down range by 400-600 lbs/ft. However almost all rifled foster slugs retain 1000+ lbs/ft of stopping power @ 100yds.
The retired guys concluded the only noticeable side effect from foster rifled slug thru rifled barrel was excess leading. I agree that my barrel is really, really dirty after 30-50 rounds. Seems to clean easy and I always see the groves when I am done. I'm sort of a rookie, but I just keep scrubbing with copper brush and running cut up rags with rem oil until I start to come clean. I would do this even if I shot sabot. a rifled slug barrel really only has micro-grooving if you ask me.
Lastly I actually wrote into Federal Premium customer email inquires about products and asked, "can I shoot TruBall thru my 870 rifled barrel?" The answer was yes with no conditions, clauses or disclaimers - Just a simple yes you can shoot it. Lead is virtually the softest metal on the planet vs hardened steel barrel. Like I say I'm a rookie when it comes to cleaning but I keep working at it and the groves are always there and symetrical when I look down the barrel when finished.
My personal opinion 75 cents per shell on sale and with rebate vs 2.5 dollars per shell on sale. Other than bullet drop - I have yet to find one really scientific answer to prove the wive's tail of foster slug in rifled barrel.
