GunWorks - Winchester Model 100 Disassembly (.308)

[Revolutionsmyname318]

My problem is with the trigger group, i drifted out the pin holding the hammer, not sure if I was suppose to do that, the trigger seems to be locked back and wont budge.

Great video thx. Just bought a model 100 in .284. The bolt hangs up once it's pulled back, not sure if it's the magazine or what. Any tips?

[BJDSEW]

@1torawi1 You probable have a switched magazine. If the magazine has 284 stamped on the back. maybe not. Alot of after market magazines out there. Hard to tell the difference between a 308/243 and a 284. The winchester 284 can cost around $90.

308/243 around $50. Thats the reason for switching.. Happens alot at gun shows, the reason you will most 100's and 88's on display without magazines.

Great video!!! It greatly helped me redirect my grandfathers model 100 and get it back into shooting condition.

Thanks

Great Video!!

How do you remove the stock from a Winchester model 50?

THANKS

[adlerbr12]

I just got a SEMI 308 and there is no way i will even venture to attempt to take it apart , this is way to complicated .

This guy is a dam genius.

@adlerbr12

The gun is really simple. Give it a try.

Thank you from Spain-Europe; great job!!

[chunkyfather]

Excellent work

[dougy05050]

Thanks alot! Been trying to figure it out so I can mail the pin back to Winchester.

[corndog417]

great video sir, wish i would have watched it before i attempted to take this rifle down.

[arizonaafield]

What do you do when the bolt won't open up at all and the safety won't move back and forth? I have a gun that belongs to my brother in law and he got it from God knows where and It won't open up for me to get the stock off.

[muleequestrian]

@arizonaafield Not to try to drum up more business, but I suggest you ship the gun to the shop. I get a few in that have that same problem. I don't teach gunsmithing online because of liability issues.

[lmberish]

Great video!! A+++ all the way. Did that rifle have the updated firing pin? Couldn't tell in the pics. I just bought one that was made in 1961 and it is all original with the original firing pin which I will replace very soon. Thanks for sharing your video on dissassembly of this rifle.

[muleequestrian]

@lmberish It has the flat old firing pin. Winchester did a recall in 1991 because of the firing pins

[kbsdn45]

Great video, Jim. Thank-you for it and your service.. :-)

[safeinsuburbia]

I took mine apart and did the firing pin recall. When I removed the barrel from the stock, the trigger assembly fell off from under the rifle. It wasn't connected like in your video. When I finally got it back together, it won't eject and misfeeds. Any easy fixes? Or, should I send it to you to fix (if you do that). It's never been fired by pop, since he bought it second hand about 20 years ago. Now it's my project. Thanks.

[safeinsuburbia]

@safeinsuburbia Ejection problem only with the aluminum snap caps. Live rounds eject well manually. Now if I could only figure out how to keep it from jamming so much when firing. Hopefully, a good cleaning will do it, but I don't have my hopes up.

Great video. Thanks.

[muleequestrian]

@safeinsuburbia

What type of jam are you having ? Failure to feed from the magazine, failure to extract when the gun is fired ?

[safeinsuburbia]

@muleequestrian When I load the 4 round magazine, and slide the bolt back, there is no problem with feeding or ejection of all 4 rounds. But, when doing this, the soft point bullets get dents in the sides of the soft points. I wonder if this is normal. Seems strange that a rifle should do that to bullets. I figure it will degrade performance/accuracy of the bullet.

[muleequestrian]

@safeinsuburbia

This seems normal on some semi auto rifles. The transition from the magazine to the chamber can be rough !

[muleequestrian]

@safeinsuburbia

This seems normal on some semi auto rifles. The transition from the magazine to the chamber can be rough !

The feed problem sounds like a faulty magazine. After a good cleaning, try a different magazine. These things are stamped from sheet metal and can cause a lot of trouble sometimes. I have seen quite a few problems of this nature solved by a new mag.

[safeinsuburbia]

@muleequestrian OK, I'll give it a good cleaning. I've heard of gunsmiths modifying M14 magazines for the Winchester 100. Do you do this? It would be nice to have a few larger capacity magazines for the range. I'm thinking the build of the M14 mags would also be better than original winchester stock.

[muleequestrian]

@safeinsuburbia Dented soft lead tips are normal for most semi auto rifles. Since we're talking about minute of deer accuracy not minute of angle, it shouldn't be a problem. The feed problem sounds like a faulty magazine. These things are stamped from sheet metal after all. I've seen a lot of the difficulties you mention be resloved by replacing the mag with a new one.

[safeinsuburbia]

@muleequestrian The problem is when I fire the rifle. It will feed and eject the first round just fine, but jam when the bolt attempts to push the next round into the chamber from the magazine. As far as I know, it has never been cleaned properly. I think I'll give it a thorough cleaning and try again. But, it seems like wishful thinking. Thanks

[muleequestrian]

@safeinsuburbia

Yes, you can ship the gun here to GunWorks for repairs. Please call the shop for instructions. I will tell you that parts are VERY hard to find, but I do have a couple of sources.

[muleequestrian]

@safeinsuburbia

Sorry I didn't see this to replay to it earlier. I get busy in the shop sometimes. Yes, if you'd like to send it here ot the shop, I can fix it for you. Send an email to muleequestrian@yahoo and I can make arrangements to get the gun here to the shop.

[leebrewer3]

Very helpful Jim! Really appreciate this video...

[gvismac]

Excellent video Jim, Well Done! Followed your instructions and disassembly went well. Right from start I discovered that the retainer clip was missing so I'll have to search the web and try to locate one. Thanks Jim

[mildbull2000]

Thanks jim ,awsome vid.I heard years ago they had a recall on model 100 ?

[dj0wq]

Thanks Jim,

I just used your Video to replace my firing pin with the replacement provided by winchester (see Winchester recall).

I would suggest you do the same !!!

Liked your video!

Thanks

how much would it cost to put a .308 barrel on a .284 model 100? is it as simple as a barrel swap or what?

[thereisn0sp0on]

@importsstillsuck The magazine is different too, maybe some other things. Just trade it for one in .308. The .284 models are rare and worth a significant premium over the .308 and .243 calibers. Anyone who knows their guns will gladly swap you a .308 for a .284. Heck, I'd go out and buy a .308 to swap you for your .284 if i could find one for sale at a decent price. These guns were discontinued in 1973 and aren't that common on gun shop shelves.

[importsstillsuck]

@thereisn0sp0on yea i thought of that too, just get a .308...but since i already have this, i figured it would be even cheaper just to do a barrel swap, if that's all that's required to turn it into a .308. My .284 isn't for sale, it was handed down to me, the gun show by me offered me $700 for it, I couldn't do it, my dad said go for it, but that's not something I could have done lol. The gun probably has maybe 100 rounds through it, 40 of which were from me last summer shootin beer cans.

[thereisn0sp0on]

@importsstillsuck Your .284 sounds like a sweet rifle. I wouldn't sell it either. I also wouldn't mess with it, you will destroy it's value by rebarreling it and it would probably be cheaper to just buy another gun. Figure at the very least you will need a new barrel and a new magazine. The .308 magazines run $50 and a .308 barrel is $350 from Nu-Line, let alone the cost to have it installed and headspaced. For $400 you could buy a .308 outright.

[importsstillsuck]

@thereisn0sp0on yea it's in excellent shape, like i said I would be surprised if there has ever been more than 100 rounds through it, according to my dad my grandpa never shot it other than when he first got it, after he shot it for the first time it kept jamming, so he put it away and never really messed with it over the years, then gave it to my dad, i remember him shooting it once and I doubt he went through a full box, the he gave it to me, and i shot it, it jammed

[importsstillsuck]

@thereisn0sp0on gander mountain fixed it and i then went through 2 or 3 boxes of rounds and for the most part it's reliable, figured out if i put a little gun oil on the brass it won't jam. just wish .284 bullets weren't so damn expensive. $45-$55 a box.

my 7mm is only $27 a box for the cheap ones

[thereisn0sp0on]

@importsstillsuck Yeah, .284 ain't cheap, that's for sure. I can see why you would want a .308, much easier and cheaper to find ammo. From what I understand the M100s work fine if kept clean and oiled. I picked mine up (.308) on the cheap over the summer but haven't shot it yet due to the firing pin recall. I pulled my pin out and gave it to my FFL dealer friend to send it back to Winchester. Hopefully when I see him Sunday he will have the replacement pin for me. Has yours been repaired?

[importsstillsuck]

@thereisn0sp0on yea mine had the update kit put in it a couple years ago (40 or so rounds ago, can you tell how often I shoot?) my uncle has a model 100 in .308 he says it works flawlessly, I wonder if the jamming problems were mostly associated with the .284 models. I wonder if anybody could make a custom 20 round magazine for a .308 Model 100. Build a sort of poor man's M1A, that would be neat.

[thereisn0sp0on]

@importsstillsuck I can't blame you for not shooting the .284 often, it's expensive. My "fun gun" is a .22 short autoloader. Great for cheap plinking and very low noise with the CCI CB shorts that I use. On the 20 rounder, since the M100 is loosely based on the M14, I can't imaging it would be too hard to graft an M1A/M14 20 rounder onto the base of a M100 mag.  From what I understand there were 10 round aftermarket mags for sale at one time. I'd love to find one of those.

[importsstillsuck]

@thereisn0sp0on my little fun gun is a walther P22, it jams if you use subsonic ammo and jams less often when you use the cheap rounds, but works fine as long as you use CCI mini mags or stingers. But anyways I guess I'll leave my M100 alone and save for a scope for my 7mm mag, and save for an M1A...gonna be hard though I hear gas prices are going to $4-$5 a gallon in 6 months.

[thereisn0sp0on]

@importsstillsuck Yeah, you can't beat .22s for cheap plinking fun. I'd like an M1A myself, but for now I'm happy with the M100. I really love the way it handles and the factory iron sights rock. Keep saving for the M1A, gas price hike or not, if you keep socking a few bucks away when you can you will get it eventually and sooner than you think. Enjoy your grandpa's M100 for what it is, and keep it clean and lubed like shown in this excellent video. :-)

[GunslingerRob]

Excellent video!! I admit I was a bit intimidated about taking my 100 apart,but this video shows the "how to" of it wonderfully!!I'll check out your website,Mr. Green!!

[gadjeep]

Great video of a great rifle! I'm about to replace a worn extractor and spring using the Nu-Line reliability kit and this video was a great help. Cheers from a Native Mainer!

[ILikeWeapons132435]

I have heard about the recall on the model 100 and what years of production does that apply to? How many different models of this gun exists? Do the 308 mags fit and function in .243 guns? Are there bigger mags (10 rounds) out there? Where can I find mags for this gun? What is the estimated value of this gun? Can it be Parkerized?

[bluecommando18]

Excellent how to video. Thanks Jim
