I own a Mossberg 500 12 ga and a Remington 870 20 ga. I am thinking about converting one to a slug gun as the public land i hunt only allows shotguns and muzzleloaders.

I know there are more bullet selections in the 12 ga, but if i put a slug barrel and scope on that gun I have no duck, turkey, dove and rabbit gun. Truthfully i only need it for Turkey.

My question is which gun should i convert. I want to be able to shoot to 100 yds accurately enough to kill a deer and I am wondering if the 20 has that power. I was told yes, but want some opinions from the shotgun guys.

thanks,
