Had good luck in the smoothbore days w M500s out to 150 yards.
Went 870 when rifled bbls came out.
WW Hi Impact Supremes were sub 2" at 100.
Good to shake the snot out of the sinuses too.

They dropped that slug and I sold my gun.
Had two 870s I ran w that ammo.
Wicked good.

Last slug deer was w 870P.....and Activ slugs.
Just an old school fun hunt. Double lung and busted off shoulder.....100" eight point ran 125 yards total.

Surprised me. Blasted him at 25 from a stand
