I got the chance to try the MAD Gobbler Max .660, MD-1210 in my H&R Topper Deluxe Classic 3" 12 ga. Ammo is 2 oz. Mag Blend 5,6.7's.
My buddy ordered one for his sons Mossgerg 505 20 ga. and they sent him the 12 ga. invector. He called Midwest and they promptly sent him the correct tube and didn't want the 12 ga. choke back. I wonder why?
I have never seen a choke that wasn't polished inside.This one is as rough as the outside of my barrel.
I see lead shooters posting better patterns. This was my best 40 yd. pattern.
123 with Mag Blends?
Maybe I expected too much out of my rabbit gun.
