Target shooting slugs out of a rifled
cantilevered barrel. Using 4 different
brands of sabot slugs at 70 yard with a scoped, rifled, cantilever barrel. after 3 shots my 2 inch group is gone and the shots begin to rise and spread. I haven't been able to check the scope with a laser bore but I've swapped everything
(Scope, Ammo, gun) all is tight and clean. Is the barrel or cantilever flexing from the heat?

I would think its the barrel as the cantilever should not get a lot of heat after 3 shots. I am assuming Remington I would contact them and see if the can help you (336) 548-8700

Hi Michael, How quick are you shooting? It takes alot to heat up the barrel enough to flex it.

James G. · Answer

Michael, normally the shot groups will spread with cantilever ffex. I would fire at least three 3 shot groups to get an idea of what's happening after the 3 shot. I would move in to 50yds and shoot 3 three shot groups back to back. My guess is that if everything is tight, the scope may be wandering zero when firing.
