I have a 300xl that my Dad bought new in the mid 70s. It's fired 1000s of shots, everything from slugs and buckshot to Target and even alot of reloads shooting skeet. One of the guys had a Browning A5,couple of them had semi Remington's and another had a 900xl. The only 2 that would cycle reliably every time with the reloads were the ithacas. I know with 100% certainty that my 300 has never jammed. Mines definitely seen better days.Theres a chip out of the bottom of the buttplate from being dropped. The forend was cracked from the front almost all the way to back that has been glued from them rolling the car years ago out duck hunting.
Mine anyway is extremely reliable and with the full choke and 30" barrel is the tightest patterning shotgun I've ever owned. Out to about 20-25 yds I can aim about 2" over a grouses head, and tear theirs head off and rarely put a pellet in he body. It's 1 gun I'll never get rid of. I think you'll be more than happy with yours.
