Not arguing their usefulness, just saying it doesnt really apply to this end goal.

Great! Now you can get it cut down, etc. I think you'll be glad you did.

I'm thinking the best approach will be to have the barrel shortened to match the OAL of the ruger GSR. This will mean chopping 4" off the barrel. Thats not a massive change, but it'll leave me with a barrel that is 20" from the breech face, which is about 18" of exposed barrel in front of the reciever, this is in contrast to the 16.5" barrel on my GSR.

I could have it shortened to 16.5, but then it'll be alot shorter than the GSR and I believe that would make it handle differently. Anybody have thoughts on this?

So....Yup, I will be sending it off to the gentleman who offered to cut and crown tomorrow. He's also going to D&T a front sight hole for me.

I was going to ask him to D&T another hole in the barrel, as well as the scope base itself, to strengthen the mount, but i just jerked on the thing quite a bunch and i cant even get it to flex, I'm pretty sure it'll be solid unless I REALLY wang it on something while in the field, in which case I probably would have damaged the scope if it broke the mounting screw, so, i'll probably just leave it as is.

Now, to watch auctions and piece together what I need to get a decent set of irons on this thing....

And while the barrel is away I will be repairing the stock crack.

The LOP on the stock is about 1/2" longer than the GSR when you line up the grips/triggers. I may get a wile hair and try to shorten the stock, but i dont think it's enough to make a difference. The stock does need profiled to better match the buttplate I replaced, so, who knows. That will require actually refinishing the stock though.

So, woohoo!

Yeah I would match the OAL of the Scout since you're making a set. Working on the stock will give you something to do while the barrel is away. Fun stuff. I like where you're going with this.

Now, while the barrel is taking its cross country trip, I will focus on other aspects.

Stock is setting up. I spead the split and packed it full of acraglas, then clamped it down. I also used acraglas to fill in the super stripped out sling swivel holes in the stock (I'm aware the 42C never came with swivels, but clearly somebody added some).

I packed the holes with acraglas, and will drill them out for the replacement stock style fixed swivels that should be arriving today. Will add an appropriate shooting sling as is found on my full size scout.

Not sure if i am going to modift the LOP on this stock. Including the butt pad, it's really only about 1/2" longer than the scout rifle. If i choose to chop that, i'll either need to source a cut to fit butt pad, or i'll have to modify the actual profile of the stock, and refinish the whole thing. . Woodworking is not my strong suit.

Obviously on this rifle I'm not super worried about keeping it original anymore, haha.

Following that, the next order of business will be to keep my eyes peeled for some inexpensive sights. Looks like to stay close to original I'd need a No.4 rear sight and 106 front. I figure any front ramp sight of approximately the right height would work, but I'll need something mossbergish for the rear sight. I'll keep my eyes peeled on the auction sites etc.

So, tonights adventure.

Came home, pulled the clamp from the stock. Unless I refinish the whole stock, its definitely noticeable, but as long as its solid, i dont care too much. We'll see if i'm bored enough to refinish.



So, I went and installed the new sling swivels on both this stock, and my S26C.



I had ordered a 1.25" Straight Shooter sling for the S26C (it was cheap on ebay), which arrived the other day as well. Now it's on the rifle. I actually ordered ANOTHER Straight Shooter sling today (cheap on gun broker) to replace the 1" straight shooter sling that came on my 146B-A. So, i pulled that one off the 146, and installed it on the stock for the 42C. I attempted to "sling up." in a shooting position and this happened....WOMP WOMP!



Okay. Well, there goes a nice 60 year old sling. Not being easily discouraged, and being as cheap as possible on this project, I went to work. Dug around my leather/kydex holster making crap and came back with some chicago screws. I drilled out the rivets in the brass frog, then filed down the chicago screws to be the right depth, and punched new holes in the leather. Overall, I think the sling lost about an inch of length. Is it the worlds prettiest thing? No. did it save the sling? Yes. Will it work? Yes. If i get REALLY fancy can I go to home depot and buy two brass machine screws? Yes. Am I gonna? I dunno, that'll cost like a dollar.

The result is functional.





So, thats it for tonight since I had the unexpected adventure of working on the sling.

Here's my mossberg family....though the 42C is looking a little naked at this juncture. I havent even shot the S26C yet, but for some reason it's my favorite feeling and looking one of the bunch right now. Maybe because it's the most "scouty" in its natural form?

Reasons:

1. Because those are single shot adapters to the best of my knowledge, and do not allow feeding from a magazine. they have to be loctited into the chamber, then single fed. The adapters are only reusable if you are "careful." even if this is reversible, its a pretty big undertaking to install and remove, it cant be done on a whim so you cant readily switch calibers.

2. .32acp seems to be the smallest caliber for a .308 adapter, and that costs more to buy than 5.56, so not exactly saving a ton of money.

3. Even if they fed from a magazine, getting enough of them to load 2 magazines would end up costing a few hundred bucks, vs. my $9 investment in this free rifle. If you really wanna get down to it, the scope and the mount, which were purchased for other projects cost $50 and $20 respectively, so my total investment is $79, but I don't count it that way since i already had all that stuff laying around. Still would cost way more to get either 10 or 20 adapters to run in 2 5 or 10 round mags :-)

4. using a camber adapter in my rifle wouldnt give me an excuse to breath new life into this otherwise worthless part of my collection. a worthless part of my collection that with the exception of not having the forward mounted rail prior to my modification fits precisely the same manual of arms as my GSR. :-D
You're not missing too much by skipping the cartridge adapter.

I have a .32 ACP to .308 adapter. The good thing is, you don't have to glue it in the chamber. However, you do have to single load the cartridge and adapter as one unit into the chamber. The GSR extractor will go right over the chambered adapter.

One thing that may not be known about these adapters is that closing the bolt may not be possible with some .32 ACP ammo. Since .32 ACP headspaces on the semi-rim of the cartridge, a variance in thickness of the .32 ACP rims can prevent bolt closing. From my experience, European .32 ACP has a thicker rim than American .32 ACP. I had to make a lapping tool from a spent .32 ACP case to deepen the seating of Euro .32 ACP cartridges in the adapter so the bolt on my GSR would close.

Another thing is accuracy. .32 ACP out of a .308 barrel will probably never be as accurate as .22LR from a .22LR rifle. I mean not even close. Two things likely conspire against .32 ACP here. The long bullet jump to the rifling through the adapter and the rifling twist in a .308 barrel likely isn't suited for the .32 bullet.

Here's some pics of my adapter, etc. as used in my GSR.

I've been down this road nearly two winters ago. My thought this winter is to finally modify a rail to put on a real scout type scope.

Below is my self modified .22WMR rifle with the LOP reduced by 1/2" and the barrel cut to 16.25". It's still pretty close in overall length to my 17.25" barreled GSR. Look at the location of the triggers between the two. The .22 WMR rifle actually had a longer LOP than the GSR with one spacer in it.

I think you'll like a shorter barrel for this project.

THanks for the info on the adapter that's definitely a useful review considering it's the exact situation I was looking at.

I am still having mixed feelings on the overall length. Here are some pictures
Comparing the two rifles. They were lined up using the trigger and pistol grip area. Seems odd that keeping a 20" barrel on the Cub Scout will put it at the same length as my 16.5" GSR.

4" off the barrel:


1/2" off the stock:

Oh man this thing is nasty. All I did was clean it with some simple green and hot water to degrease. At some point in the last 77 years somebody removed like 95% of the original finish....definitely not 100% and oiled it. Poorly.

The whole thing stinks like an old cigarette too lol.






I steamed out several dings. I will sand it and begin using boiled linseed oil and 0000 steel wool between coats. We'll see where that gets me!

And considering the terrible condition of everything, and that I am refinishing, I may just chop 1/2" off the back :-). If not I will chop a tiny bit just To square It off..

Regarding the barrel length dilemma to match the overall length of your GSR. It may seem like the handling between the two guns will be the same, but in reality they won't match at all, IMO.

Sure the barrel or butt may be the same distance above the ground or above your shoulder when slung. However, the odds are your rimfire weighs at least a pound less than the GSR with both guns being empty.

My cut down .22WMR weighs about 6.3 lbs as seen in the photo, all up with sling, three magazines, and 33 rounds of ammo on board. My GSR weighs in at 7.75 lbs. all up as seen in the photo, but with not a single round of ammo in it.

You can feel that weight difference readily. Plus, the little rimfire bolt is a short stroke flick compared to the long stroke cock-on-opening job on the GSR.

What I mean by this is, it is a great idea to try and match a .308 GSR with a cub scout for practice, but they still feel and handle completely differently. So, don't worry about if your cub scout has a 18", 17" or 16.5" barrel instead a matching length 20" barrel if you plan to shoot with a scope. Whether scout type or not.

Without a scope? Then you may want the sight radius the 20" gives you.

I don't know for sure how you feel about it, but a short 16.5" barreled rimfire will fit in a few more places than a 16.5" center fire will.

You may be right. I'll think about going down to 18".

So, all of y'all i need help.

Tru-Oil vs. BLO vs. Tung Oil

Which should i use. Keep in mind I already have BLO and dont want to spend $8-$15 on new finishing products.

I understand BLO is less water resistant than tung oil, but only marginally so. I understand that BLO "can" go rancid and "can" grow mildew. I'd imagine that not likely in a super dry environment and if applied correctly.

I understand BLO will orange or yellow some more than tung oil.

I dont know much about tru oil other than it has varnish and stuff in it and will leave a stock glossy, which could be de-glossed with steel wool etc.

I wish I had good advice regarding wood stock finishes for you.

I've only refinished 3 gun stocks in my time, and somehow always ended up using whatever wood stain I had on hand that looked decent and then just covered the stain with a spray can of polyurethane. Of course, I used steel wool or sandpaper as needed. Even that .22 WMR was just smoothed with steel wool and hit with polyurethane spray.
