When bare LEAD comes into contact with rifling in a barrel, some will come off and become set inside the groves of the rifling. The same thing will happen with the plastic from the Sabots but just not as bad. Now with the Challanger's they are already rifled. There will be a conflect between the two different riflings (slug & barrel) which will magnify the lead fouling of the barrel. This conflect will also hinder accuracy.Annapolis wrote:John,
Why will Challenger rifled slugs foul up my 870 rifled barrel?
Rifled slugs should only be shot out of smooth bore barrels and leave the sabots for fully rifled or rifled choke tubes.
Hope this helps.
