I've fired slugs from my 10 gauge BPS , and like Will says , it ain't that bad .

For some reason the 10 Gauge has this "mythical" reputation of tearing your arm off at the shoulder , giving you extended range , blah blah blah.....

All a 10 gauge really does is throw a bit more shot out there from a bigger hole at the end of the barrel .
You may or may not get a better pattern , depends on how your gun and specific load get along .
Most are heavy enough to counteract the extra powder/shot charge .

If you wanna feel something that hurts , go fire a few Hypersonics through a light 12 gauge .
That hurts !

"Politically correct" was initially coined by Leon Trotsky to refer favorably to those whose views remained in sync with the ever-shifting Bolshevik Party line. This was important, as "not PC" people risked prison or death.
