Really about the only thing that will bug me about it is I will have to drop the cheek pc to remove the bolt. I'll have to see what I can do for that to make it a tool less option.

 

Is there any kind of option to make the cheek riser quick detach?

What kind of shooting do you plan to use it for, bench, offhand, positional?

 

It will be a bench rifle.

Yea I'm thinking a thumb screw or something along those lines for the riser screw. Maybe I'll get my son to 3d print an insert that I can put into the allen head for quick loosen.

 

I like the look of the stock. I think you will be delighted with it.

 

If bench why not start with a BR50 stock?
That one deserves to be used for positional shooting.

I thought the same when I read the post the other day. It's a really nice stock and one I would've loved to have when I was shooting in a 4P league. Not trying to make Auzzie feel bad but it's one of the last stocks I would choose for bench shooting, even with a bipod

 

Grantmac asks a question others may be thinking. Why not a BR50 stock?

The action screws and trigger location on the receiver are a match. The modifications are relatively minor, involving the tang, removing material for the Fortner bolt movement, and accommodating a magazine.

 

I really like this stock. To the others, please remember that shooting from the bench does not mean Bench rest. To shoot the BR50 stock you really need a full fledged rest setup. to be honest I only shoot from the bench but I hate carrying the heavy front rest. Normally I like just shooting my rifles from Bipods or improvised rests. This stock was what I wanted when I bought the CISM stock. Auzzie, Now you have me trying to design a quick release clamp for the cheek rest. Enjoy!!!

It's likely a standard metric thread (M5 or M4 at a guess), and quite possibly common to other European ISSF type stocks. If Grunig, Walther, et al don't make a QD screw, some fastening supplier will. A club made had no trouble finding M5 thumbscrews for his Gemini.

 

Yeah I was planning on looking at my Walther KK300 as you have to remove the cheek rest to clean the barrel.

 

I'm a recreational shooter, and don't do any competitions. Then why the stock some might ask.

Because I "wanted", and didn't like the shnauble end of the wooden stock. Just like the 1727 action, because I always wanted one, and I likes it a lot.

And don't worry, my flavour is not for everyone. I'm thick skinned.

I'll figure out a quick detach for that cheek pc, and hopefully the weather is better this week, and I can get out an use it.

 

Okay, so I was able to get to the range last week, got all set up. Only to discover I forgot my magazines at home, and there was just no easy way to single feed. Aargh! Frustration to another level.

It gets dark about 1.5 hrs or so after work, so it is hard to get in a short trip. Add to that it has been awfully windy the last few weeks with rain spells in between. It has been hard to get a trip in realizing I would just be wasting ammo.

Well, I just got plumb tired of waiting any longer, and made a quick trip last night to the range, as I got tired of waiting for the wind to stop. Made sure I didn't leave without a few mags as well. It was windy, and I knew results wouldn't be spectacular, but I had to get a few shots from behind the new stock.

I had simply removed the rings still attached to the scope, and the tuner I set up, before I sent the barreled action out to get the stock fitting done. So quickly mounting the scope back was no problem, and quickly spun on the tuner.

The scope ended up being off, and shooting about 4" low at 50m. Dialed it in quickly, and shot a few quick 5 round groupings at 50. Nice, still maintained a good 1/2" or less group. No I didn't measure, but they were nice and tight.

Moved back out to 100 m, and not so great. Groups were stringing vertically about 1 1/2 - 2" and some horizontal. Sure, I can attribute the horizontal to the wind, but the vertical was ridiculous.

Might have to play with the torque on the stock screws, and looks like I will have to tune the tuner in again.

The stock feel, was just fabulous. The rear bag rides just about perfectly on the back armpit pc. Lower pc, don't know what it is technically called, but she was great. The bolt movement is now different, and you have to use the bolt handle to close, and not able to use the top thumb rest to close the bolt. The was I have adjusted the grip, and trigger though, it actually feels nice. Have to wait until my son gets his 3D printer going and get a bit of a longer bolt knob design for the bolt so it doesn't need so much forward movement to close. Literally just holding the grip with the lower 3 fingers, so there is little manipulation that is required.

Overall, I really like the new stock, and it is staying stationary during shooting. Can't wait to get some more trigger time behind it, and if all is good this Sunday afternoon I will play with the tuner and dial things back in. Was using Center X last night. I was printing 5/8" ish groups at 100 m with this same ammo before the stock work.

 

A crossing head or tail wind will result in vertical differential, so the error may have been all wind and not a bedding issue.
Good luck with your project and happy shooting.

 

Sounds like you are the path!

 

It looks horrifically functional. Glad you like it.

 

Okay,

I was able to have another go at the range on the weekend. Best groups running around 5/8", including flyers. Printing on top of each other for like 4 or so shots, and then start to open up. Worst groups in the 1 1/2" range. Very weird that way.

It looks like I will need more time on the cheek rest, and to just get the perfect height, and rest on it. Seems like I may be moving on it a bit. New to the squarish corners on it, and may have to see what I can do there to be more consistent on the rest. Of course this time I forgot the bipod, so I was using a Caldwell front rest, and may have been moving a bit more on it as well.

 

With the goal of bench shooting just drop the cheek piece until it makes no contact.

 

You inspired me to change my CISM to a Chassis. I ordered one of the AI AT-X stocks from Anschutz, should arrive end of this year.
