Smile Winchester Model 100 barrel replace?


Registered Users do not see the above ad.


Hi, guys, I have some problems with a Model 100 .308, and the chamber seems to be the cause. I's like to know if it's possible to change the barrel, because I read somewhere else, that barrels can't be removed and put back on gas operated rifles, which might be the same as placing a new barrel on a gas operated action. Has anybody done this around with success?

I guess they're worse than yours. My extractor in fact takes part of the case rim. I 'll take it to a deep clean process with a gunsmith. If it remains the same, I will get rid of it, as a whole thing, or in parts.

i'm told that your problem may be helped by polishing the chamber. it seems your cases are actually getting stuck. My problem is the extractor is disenguaging from the shell. haven't figured out why yet.

You might be able to save it with chamber polish. Your other option, if you're a handloader would be to have the rifle rechambered to 30/284 as it is a longer chamber than your .308 and is based on a cartridge the rifle has been chambered for and used the same case head size as the .308. Just a thought, I try to get the chamber polished first.

Yeah, that could be a feasible option, despite the that I'm not handloading yet, so 30/284 shells aren't easy ti find at the store. But, rechambering might be my semi-last chance.

The 30/284 is a wildcat round, so you won't be finding ANY rounds at the store for it. You simply take a .284 Winchester casing and run it through the proper set of dies for the wildcat round and fire it in the chamber and it's formed and ready for load developement. The reason I suggested this round is that your rifle was originally available in the .284 Winchester so you could get magazines that would work with the new round. The .284 casing is longer in the body and larger in diameter than your .308 round the chamber could probably be cut to accomodate it. The last reason for the wildcat is, or course, that your barrel is .30 cal. The case head size is the same so there would be no bolt work required in this instance. You would have to discuss this with a gunsmith to ensure it's feasible as I've never done it. The .284 casing has a powder capacity of the 30-06 casing so you would likely see some imporved performance with heavier bullets over the .308.

You would have to like to play with stuff to go this route as it would probably be simpler to just go get another rifle if you can't fix this one. I was just offering the suggestion as a possible fix if you are attached to the rifle.

You would want to talk to a very good smith about this, not a "yep we can do it" type who will do the work and if it doesn't work afterwards leave you holding the bag. The conversion should be able to be done for $70-140 plus the cost of a .284 magazine for the rifle. Your dies for the wildcat round would add additional costs over standard dies.

I appreciate your comments very much. I'll seek for a reasonable solution to the problem. A barrel change will cost me around $300, so I guess I must be sure of my chances before wasting more money in a 1967 rifle. I can get a new H&R .308 or a .243 single shot for about $200. A very elementary gun, but with much less parts to deal with.

If your going to part out your model 100 I would certainly be interested in buying it.

Kubali, Before you give up on that M100 Try to polish out the chamber. Disassemble and take a piece of wood dowel in an electric hand drill ,with a slot cut in one end and wrap around the dowel a piece of emery cloth 320 to 400 grit and wet polish with wd40, use lots of wd. Run in and out 75 times. Clead up real well and test fire. If it still sticks try another 75 times. With 400 grit you can wet polish quite a bit with out worring about opening up the chamber dia. to much. But you can get it too smooth and this will not let the brass form a gas seal necessary to hold back the gasses. So only polish enough to get the cases not to stick.Look for marking on the cases which will start to fade as you get a polished chamber. Bobby

OK, I'll try that procedure, before anything else. Thanks Bobby.

Kublai, Have you had any luck yet with that M100?Polishing out that barrel is not some thing hard to do. Bobby
