Ruger-Feddersen 10/22 SuperStock
 
Hello. I've spent a few years over on the 10/22 forum, but my 2nd 10/22 project looks like it fits into the SuperStock class. I've had a lot of fun with my other 10/22 going through a couple of bull barrels and two stocks over the years, and a heck of a lot of DIY mods and tinkering, but this will be my first time trying out a sporter barrel, so I'm hoping to learn a lot (and hopefully contribute) on this forum.

I started a post on this project on the 10/22 forum, but here are the highlights:

My starting point is a Feddersen receiver that I was lucky enough to get for free, and a Feddersen 18" factory contour barrel. The rest of the rifle are either all factory Ruger parts that I've polished or tuned, fabricated pieces, with a small handful of aftermarket parts (hammer bushings and pins).

Here's what it looks like so far:

Some bolt work, typical radiusing, headspacing, extractor tuning and profiling the firing pin. I also added a tension pin in the firing pin slot, after these pics were taken.

Cleaning hole drilled, plus added a rear anchor that is bedded into the stock:

Currently the action is bedded, with brass piller at the takedown screw, and barrel free floated. But, I'm guessing I'll be experimenting with pressure pads after I see how she shoots.

I have the trigger breaking consistently at 2lbs, for now.

Here's my project post:

Very nice little rifle!

Welcome to SuperStock!!

I've been watching your build thread since you started it.
It looks like you should have a shooter ! Nice work :bthumb:

By the way I really like your stock .

First range trip results. I'm going to do a couple of needed mods before the next trip, but I can tell this rifle is going to shoot very well!

First thing I do with EVERY stock is remove both sling swivels.

Wish they would just leave them off as it seems few people actually uses them! :D:bthumb: http://i57.photobucket.com/albums/g2...psdbe0d614.gif

Clem-E 04-24-2017 12:47 PM

lol. I like them since I typically shoot off a bipod..... :p

I ordered flush mount QD sockets, and swivels that should solve that problem. I added the same ones on my shotgun last month and they work pretty well. I'm not going to use the sling swivels as an excuse for my poor performance, but they added an additional challenge on top of me trying to learn to shoot off of a rest.

I don't want to mess up the lines/looks by adding a bipod, which I prefer for shooting, but I may leave the front stud in case I change my mind and want to add one later. I have a few days to mull that one over.

Vincent 04-25-2017 09:04 AM

It only takes 1 minute (if you are real slow) to put one back in if you change your mind. :):t

I doubt it is a good idea to constantly screw them in and out but once or twice you should be able to hit the same threads and not mess up the hole. :D:bthumb: http://i57.photobucket.com/albums/g2...psdbe0d614.gif

Same here. I quit taking off front sights when I had to figure out which were which and label em all in the sights drawer. If, err, when, I croak, the wife knows nothing about the studs and sights when she'll peddle em to the first gun sheeny that scarfs em all.
I have a permit to hunt from a motorized vehicle and the front sling stud can be rough on a window sill.

Now that I've switched over to a torsion trigger return spring, I used the hole from the old coil spring to add an overtravel stop screw, as others have suggested. I decided to go straight through the rear of the trigger guard, rather than down though the hammer strut hole, so I can fine tune if necessary, with the action in the stock. 33 cents and 10 minutes to drill, tap, install the screw, and adjust, and the job was done.

I know there are arguements on whether a stop is needed and wheher it help or harms accuracy, but it does feel good (especially with the 1-1/2 lb pull).

The QD sockets and sling swivels arrived today. I think for now, I'll just replace the rear swivel, since the front doesn't interfere with my shooting rest. This way, I only need to disconnect the rear swivel when shooting from the bench, and since the socket fits flush, it shouldn't interfere with the rear bag.

Oh ya, last night OCD kicked in, and I cleaned up the bedding a little, filling some voids and fixing the portion contacting the top rear of the receiver, where the epoxy from the earlier job sagged down a little. Probably only a cosmetic improvement on something only I see after disassembly.:coco:

EDIT: I couldn't find my extra roll pin when making the bolt buffer, so I had substituted a short length of galvanized steel rod. Looked and felt sturdy enough, but here's how it looked after my first range trip:

http://oi64.tinypic.com/xliihg.jpg

When using a 1/8" roll pin on my other 10/22 (inserted in 1/8" fuel line), there's no hint of wear or bending after 20K+ rounds of mixed SV and HV ammo. By contrast, less than 250 rounds of standard velocity ammo, and the galvanized rod was no longer useable. I read that some folks feel that when shooting SV ammo, the bolt buffer is barely touched, but it seems like it still takes a little beating.

The pin is now replaced with a 29 cent roll pin from Ace, which I expect to last a lifetime.

I took the day off and hit the range first thing in the morning today. Got there 1/2 hour before it opened, and grabbed one of the last two benches (the bench rest guys get there pretty early).

Pressure pad testing:
I came equiped with various rubber inner tube pads, and systematically applied the pressure pads in various positions up the barrel channel, and various thicknesses, shooting 5 shot groups in each position testing with both CCI SV and Wolf Match Target.

I was a bit frustrated by the results. Some positions showed some promise, but I couldn't get consistent results. The best position ended up being right in front of the v-block, the area I would bed if I didn't already have the rear anchor. It produced fairly consistent results, albeit not the tight groups that I was looking for, averaging around 1/2" give or take. So that's the extent of the bad news.

Shooting rest practice:
The good news is after tinkering with the pad, I had a great time shooting the rest of the day, mainly because I was concentrating on technique, getting used to shooting off a rest, with this light sporter setup. I switched to a target that has several small 1" bulls, with an orange center the size of a nickel, and sort of made a game of it, by shooting 10 rounds at each, trying to keep everything in the orange, without touching the outside black ring.

https://drive.google.com/open?id=0B9...2lqWHJmMmM5Nmc

I tested various holds, squeezing the rear bag, adjusting the front rest, lining up the bags, and just a lot of general experimentatiion. The 1-1/2 lb trigger felt great, and my groups kept tightening as I went along trying different things. I threw a couple of rags over both bags to see if that would help the stock ride more freely, and they had a significant effect. Now I know why the benchrest guys use all of those tricks (baby powder, dryer sheets, etc.) to allow their rigs to recoil freely.

Results improving:
By that time, and about 500 rounds later, it was getting pretty easy to keep all 10 rounds in the orange, and I had a lot of fun getting there. I still like shooting off a bipod, but have to admit I'm have a great time with this SuperStock stuff (the lighter weight is more challenging to control); dialing things in with the rest and bags and seeing the results is pretty entertaining. It was fun, since I was shooting cheap ammo, and I think the practice will pay off when I move up the ammo food chain.

Technical:
Safety testing the trigger revealed no issues, and after ~500 round with no malfunctions, doubles, or reset issues, I think it's pretty solid. I did test the pull weight when I got home and it was up 2 ounces (1 lb 10 oz), which was a little odd. I'll be taking it apart and seeing if grit got into it, etc., and see what it is after a thorough cleaning.
There were zero failures of any sort with ammo, feeding, and cycling. I scrubbed the chamber and ran a couple patches though after about 300 rounds and then again when I was packing up.

Next steps:
I decided that i won't ever be adding a bipod to this rig, so I'll be installing the flush mount QD sockets so I can easily remove the sling when shooting at the bench. An epoxy pad will replace the rubber pad right in front of the v-block.

For my next trip, I'm doing some more research on how to slick up my bags to free up the recoil. I'm thinking about mounting up my T-36 scope, since I'm spoiled by the magnification since my eyes are pretty bad now.

Lastly, one of the old bench rest guys reminded me of the o-ring trick for tuning these skinny barrels. I tried them before on my bull barrel and they actually do make a difference, and are a lot less ugly than the deresonator, which I've also tried (and that got me started on the whole tuner thing). Since pressure pads didn't seem to work, I'll try skinning the cat another way. I'm not sure if I should be happy with 1/2" with cheap ammo, but I have a feeling I'll get more out of it.

Great!
 
I intend to take the time to make more detailed comments on a number of things in this thread but right now I am finishing up my new rifle and watching racing on TV.:o:o I just want you to know I REALLY like this thread and all your detail and photos.

I hope I can also help you just a little on the technique of bench shooting a light weight semi auto....NOT like shooting a B.R. rifle that much is certain. I never tell someone what to do but I have learned a bit shooting these things for 15 years from a bench and would like to give you a few things to think about. It is so great to see a member doing their own work and learning the good stuff as you do it

Again, what a great thread. This is what SuperStock threads are all about! :D:bthumb: http://i57.photobucket.com/albums/g2...psdbe0d614.gif

I think we are using the same rest.
I used a piece of .015 Teflon sheet on the front bag. I wrapped it with tape for a few days, to let the Teflon take the shape. Then used a dab of superglue on the back, and front.
It's been on there for over a year, and hasn't came loose. I think it helped me, and it is slick.

Yup, same rest, and maybe same rear bag (mine's the tall version). Funny, I was looking at teflon sheets on Amazon and researching whether it could be shaped with something like a heat gun. Good tip on the tape, thanks.

I've been reading the thread on your SuperStock. Interesting on the Permatex. Might be another thing for future experimentation! Fun stuff.
