Hey Folsom - I've heard of LGS shooting a customers gun while on hold. I had it happen with a brand new S&W 686. Not to rekindle your aggravation, but t stinks and for them to have done so at all. Particularly w/o cleaning. it's just plain wrong. They should be called on it.
- I'm not a true expert of the ilk of some here on MOF, but have now stripped, fiddled and fixed too many 1894's to count. While some believe in operating the lever with serious authority, I'd be careful forcing the lever too hard. While it's a tough rifle, there's stuff in there that can break. Plus the 'lever'age of forcing the lever can add to the infamous Marlin carrier line, where the snail cam on the lever makes contact with the bottom of the carrier to lift it up. Basically, the deeper the "line" on the carrier, the more likely you'll eventually have feeding problems. Something may be wrong that could likely be easily fixed. But you'd need to be able to pretty much fully strip her to get at it the carrier to check it out. If it's cycling 357 rounds fine, but chokes on 38 spl, its likely the overall length of the 38 spl round your using. That happens sometimes. I did a piece on Marlin Owners forum some time back about the carrier differences on the 1894 C (357's). I examined 3 distinctly different carriers. It's in the reference section here.
http://www.marlinowners.com/forum/n...fferences-project-notes-comparison-pic-s.html. You may be aware there are 1894C (& CS) that don't say 357
& 38 spl on the barrel. Most will still feed 38 spl, even if the barrel isn't marked as such. But I have a couple that don't like 38 spl on the extra short side, say under 1.45 in overall length, if you have calipers to check yours. The longer, the better. I know you have a bunch of .38 spl you want to shoot in this rifle, but just be aware some 1894 C/CS struggle a little with .38 spl.
Very few on this forum know more than WIDDER when it comes to Marlin 1894. Maybe he'll chime in here later. You'd need to be able to describe very carefully EXACTLY what is happening as you operate the lever in slow motion and closely watch as best you can inside the receiver. Preferably with a small flashlight in your mouth. If you can describe what is happening, likely you'll get help here to fix it. Careful jut giving up and taking to a local gunsmith. Maybe your lucky in your locale, but most don't know Marlin lever actions. I'm in Ohio with LOTS of dealers around, but few smithy's I'm aware of that know Marlin LA's.
The inner workings of the Marlin 1894 receiver is elegant & simple, but the timing of what happens at what time is important. If ANYthing is wrong with your carrier, it could definitely effect .38 spl loading. You'd have to strip her down completely to find out for sure. In case you don't know the inner guts of the Marlin receiver, or what the "carrier" is: - the carrier is an arm that swings up and down as you manipulate the lever. It both holds back the next round in the mag tube and lifts a round up the receiver and into position for the bolt to slide it off the fully lifted carrier & into the chamber. The "timing" of what happens when can cause issues. You can find lots here on MOF about various jam fixes. They are more common using .38 spl. But you need to know what is happening. For instance, is a round slipping in UNDER the carrier, or is it jamming as it is feeding into the chamber? Two different issues & fixes.
If yours is newer (late 80's), there is also little pin on the carrier that can snap off if the lever is forced while its in the right spot. A dealer at a gun show did that on one I was looking at that had jammed on some dummy rounds I took in with me just to check. I heard the little snap, and the lever now operated, but the carrier wasn't moving up & down. I knew exactly what happened and said jokingly "well now its only worth $250 bucks" He said, "your probably right" & I got it really cheap. A $50 carrier from Midway later, it is perfect & was worth $750 at the time (now maybe $1000).
The older ones had a more robust carrier w/o the little pin you'll read about. You'll see the diff if you look at the link above. Either way, I've gone on long here and should stop. I know the frustration starting out with Marlin 1894's that has a function issue. That's how I came to this forum & what caused the Marlinitis that has infected me. Determine just how "handy" you are mechanically with PROPER screw drivers, and your level of patience, and i bet we can get that old girl working as you'd like.
