Author Topic: Rough Barrell Spot (Read 616 times)

I have had my 336C in .35 Rem for about a year now and never had a problem with it. I've kept it well cleaned especially the rifle bore. I switched to a tight cleaning jag (.357) and noticed after I "brush" the bore and then wipe with clean patches it seems to catch something about halfway down the barrel. Very small hang up but I could feel it. I thought this to be odd and I finally pulled out a small flashlight, shined it into the ejection port, and looked into the barrel itself. Well it seems to have a rough spot in the rifling! Accuracy is very good though. I have over 100 rounds through it so far. Rust? Naaah, I keep it clean. Has any one had a similar situation? Should I return it to Marlin?

Norseman - that's a strange one. usually barrels will have roughness near either the throat or the muzzle, but to have a rough spot midway down the barrel - hmmmm, strange. It might be a casting fault that didn't get picked up during quality checks.

One thing you may be able to do, if you don't want to send it back to Marlin - who might/ might not replace the barrel - is to hand lap the bore and see if you can smooth it out. Get some Clover Polish, make yourself a tight fitting cleaning patch jag, coat it with the polish and hand lap the bore until the roughness comes out - might be a couple of hundred strokes. Your bore should brighten right up - almost mirror like. After that, if you still see the roughness in your bore, it may well be a casting fault but try handlapping it first. Just a thought and HTH.

I guess I am not going to sweat it. Accuracy is too good! I never noticed the rough spot before, because I finally got a .357 cleaning jag which is a VERY tight fit with cleaning patches which is what I really wanted. (To get a good tight wipe after brushing the bore, considering the micro groove rifling). Prior to getting the good cleaning jag, I just used the old loop/eyelet cleaning kind. You know...the kind you shove a patch thru the opening like a needle? What a difference in the cleaning results with the .357 cleaning jag for my .35 Rem.! I actually think the problem that got me wound up a bit is that it's just a sharp part of one of the the rifling lands/grooves. I have only 200 rounds or so through the barrel, I am sure that the more I shoot it, the sharp land/groove will eventually smooth itself out. I just got a little excited when I found this minor problem. If it were major, accuracy would be bad. Correct? I am just a little "emotionally" attached to this fine Marlin. I am sure you all know how I feel!

Has anyone else had a similar experience?

Norseman - yes, I have had a similar experience. The last time I got too emotionally attached to a rifle my late wife said it was either she or it. Ya know, there are still times when I still miss her - lol. Mikey.

Norseman,

Alot of times a bad spot in the rifling by the chamber or in the middle of the bore doesn't affect accuracy much if at all. I've an old muzzle loader with no rifling for the first 1/2 of the bore & it shoots into 4" at 100 yards from a bench, no worse than most new front loaders. The muzzle is where you want your bore to be as perfect as possible.
I think you have the right idea, shoot it. :wink:

Well, one more week and I head to the Magnificent Blue Ridge Mountains of Virginia to hunt and camp out with my friends! We hunt in the Jefferson National Forrest, and make camp near a stream packed full of crawdads and trout.. It's tough hunting, high ridges and very rugged. This is not hunting on someones farm, or land where you can easily go back home and have a hot shower, go out for breakfast, or meet at a local dive and eat at a greasy spoon. Thats not fun to us.
Hot coals on top and below of my dutch oven packed full of genuine Chile and beans, the smell of biscuits and gravy, bacon and eggs and real coffee from a "real" coffee pot is standard!. (I think y'all would understand). Not to mention... playing guitars and mandolins by the campfirelight with some very strong adult beverages as our wool socks dry by the fire. The flickering embers from the fire are our light show. As I write this I can hear the screech owl from memories of last year, and I soon will be where I truly feel FREE!! I will visit with y'all when I return from my trip to let you know how things went. If I get a deer or bear thats good. But just being there is even good enough for me! God Bless....

Marlins tend to have constrictions anyplace Marlin stamped nomenclature or broach-cut a dovetail. It is not uncommon when slugging a Marlin bore to encounter 3 or more "tight spots". As long as you shot jacketed fodder you'll likely never have a problem. If you decide to take up shooting cast, you may need to lap the bore.
