I purchased a 37 back in 1970 (for $130 BTW), because the bottom ejection was just the ticket for a reloader. Pull back the slide and it put the empty hull RIGHT THERE. Cool, right? Uh, no. Not in my case. This 37 did not like shooting reloads. At first, the shells began sticking in the magazine, the rimmed head was dragging on the bore of the tube. I took the magazine tube into work, and with an adjustable reamer, opened up the bore until the shell rims passed through easily.
Then, the shells began sticking in the chamber after firing. Shooting trap once a week, I was forced to carry my cleaning rod out to the stand and disassemble the gun and knock the hull out between shots. It was a great source of amusement to my shooting partners, referring to the Ithaca as "the pump-action muzzle-loader". After many torn rims and two broken extractors, I finally traded the 37 in for a Baretta BL-1 O/U.
I'm pretty sure it was the fault of the Lyman Easy reloader I was using at the time, not sizing the shell head properly, and if I was using just factory loads, I'd probably still own it. It definitely was a smooth operator otherwise.
