Mainly I use one of my two H&R USH Deluxes with either 2-3/4" Brenneke heavy field mags or 3" Brenneke gold mags. Son shoots a 20 USH w 3" brennekes too. They are all very accurate. I went 190 for a small buck one season but 100-150 is normally longest shots of course plenty of shots shorter distances.
If I'm in heavy cover and shots up to 50 yards I like my old JC Higgins 12 gauge pump. Inherited it from my Father. It's barrel is shortened w rifled sights brazed on. Action is smooth as glass. Shoot Brenneke 2-3/4 KOs cause I treasure it and don't want to beat on it. Great brush gun.
