It wasn't actually done to cut costs, referencing an earlier thread where that idea was discussed.
Then why was it done? Very few people prefer the front loading tube. I am quite certain it cuts manufacturing costs. Henry is quite good about replying to e-mail inquiries, and I believe they have read supposed replies from them in the past on this issue citing cost. The loading gate adds a few parts and cuts and the front loading system adds almost nothing. I guess if it is a matter of contention I could send them an e-mail and see how they reply.
And unloading... A 22lr with similar loading fashion I just unload out the barrel at the end of my day(Marlin 981ts). DOn't always want to shoot $5 of 44 magnum.
It might make me an idiot to say so, but I don't like my hand being around the muzzle when I am loading. It always makes me a little uneasy with my Marlin 22 and I imagine it would make me more so with a 44 magnum.
All that said, I still like the guns and would probably buy one over a Marlin right now.
