Anyone re-barreled a Marlin .30-30 to .38-55

[BobBill]

FYI - the 336 cowboy also came in 30-30 and they bring in less than the 1200 tag on the 38-55's. I'd buy a 30-30 and bore to 38-55 so you have your own chamber/bore diameters. I actually have a 30-30 barrel with JES now.

.45Cole was me plan but might be easier to do the Encore...for me.

I have replaced a Marlin 336 30/30 to with a Marlin 375 barrel. My Nephew has killed several deer and 1 bear with it. He has also shot at least 4-500 rounds of cast. He is still using the original brass he bought when we re-barreled the gun.

Twenty years ago Numeric arms had many of the Marlin barrels. I still have a few of them in 9mm, 45/70.

Watch out for marlin chambers, they tend to run on the generous side.

Apparently, the best way to ship rifle to JES is to remove wood and magazine...but how do they test rifle, no stock and magazine etc.

You put leather gloves on your hands, go outside and touch it off.
His job is the barrel.

I no longer use the USPS for mailing gun parts. in late summer, 2020, received a 1960's Marlin 39 A-DL with beautiful wood and squirrel engraved in the wood stock . When we opened the box at my FFL, we found the stock broken in 2 places at the wrist. The box had been dropped/crushed. My FFL dealer mailed it back to the senders FFL. For 3 weeks the PO could not tell us where it was, even with priority mail tracking.
When it was finally delivered to the FFL, there was no notice of it being delivered.
MY suggestion- choose carefully.

Unfortunately all mail services have their issues. 40 years of shipping expensive stuff is to ship Fedex or UPS overnight. If you use USPS the best service is registered mail. Takes literally forever (3~4 weeks typically) but the package is put in a safe at every step and the signed for, going in and going out.

For those that had this done, was it worth it? I own a 336 in 30-30 and might have it sent to JES to be bored out to .375 Winchester.
Could it also shoot the 38-55, is the 3 groove rifleing accurate with cast bullets?

My 94 Winchester/JES .38-55 3 groove shoots cast just fine. I will not shoot .375 Winchester level loads in it. That's why they made the Big Bore action. I don't know if Marlin beefed the. 336 up internally for the. 375 but they didn't make them very long.

The current 1895 marlin and 336 are all the lineage of the old 1893 safety. I think it's strong but I'd go 38/55 and shoot mid loads.

My 3 groove JES barrel shoots the Lee 250 grain plain base great. I load it to about 1350fps with 4227 and dacron. Ditto on the 375 reply. Mine started life as a Win '94 30/30 tho.

[Midohhntr]

I believe I will have my 336c done, I spoke with JES today on the phone and thinking of rebore to 38-55. It will be a good one for the grandkids to move up to. If I need more power than that I'll shoot the 45/70.

[farmbif]

my marlin 336's in 30-30 and 35 rem look exactly the same as the marlin 375 win. seem to be same dimensions when overlaid or side by side. I'm pretty sure both the 444 and 45-70 use the 1895 frame and are stronger than 336.

May I ask what do you size your cast bullet to? Was thinking of using the same mold.

Had a Marlin 30AS rebored to 356 Winchester by JES. Fast, fair and great work. I love it !

I have rebarreled quite a few Marlins over the years. Most round barrels run about $500 depending on the barrel blank I use. My own 93 is in 38-55, a rebore I did when I built my rifling machine. The 38-55 is loaded to black powder pressures, quite a bit lower than the 30-30. Marlin barrel are a little bit more than Winchester barrels to fit to an action because of an extension at the top of the barrel and square threads.

[milsurpcollector1970]

I threaded and profiles a 38-55 barrel, It wasnt as easy as a AR-15 barrel but not super difficult

Very interested in this.

Just inherited an early 80s Glenfield 30A.

Been in the family since new so I'm going to hang on to it.

I'd like to hunt with it but live in IA so can't with it as a 30-30.

Have read the great reviews on JES, will definitely call them.

Are there any other companies that bore/rebarrel 336s or are they it?

[WALLNUTT]

JES is good and reasonable.

[mattri]

Don't doubt it for a second just curious if they are the only company that does this.

[Shawlerbrook]

JES is not the only outfit that rebores, but I doubt you will find anyone that does a better job as fast and as reasonable as Jesse. Many gunsmiths will rebarrel also, but it will be much more expensive than a rebore. That said, depending on what you are starting with and what you want to change it to, a rebarrel may be the only option.
