I will be buying a slug gun soon and need some advice. I amconsidering theRem 870 in a 20 ga with a rifled barrel and scope mount. However the barrellenghtfor the20 ga comesis only18.5 inches. I was wonderingif the short barrel will have a negitive effect theaccuracy of this gun.I was also wondering how effective this gun will be out to 125 yards.Please let me hear from you.

Thanks
