Tuning a sako extractor and 788 6br build

[Fast14riot]

Bolt handle modified for easier left handed use?

Your guess is as good as mine. All I know is the story I was told.

Sure hope you didn't pay a lot for that rig. That thing looks bubba up'ed enough I don't think I would shoot it.

Didn't pay much for it. I trust the Smith that put the barrel on it and I got it from him. The action is real nice and the nice thing about a sako style extractor in the 788 action is it's one of the better actions to do it to because there is no raceway and it captures it in the event of a ruptured case/over pressure. The level of finish isn't great, but the actual work seems to be ok and no glarining safety issues I see.

Here's a video of it functioning properly, but before being polished so its a little sticky still. Ejector removed in this video.

That bolt is how rules get added.

Wanna hear a funny joke
Olympian and top AMU shooter Gary Anderson, the guy who tge air rifle range is named for at Perry , has a rifle on display with a similar bolt handle , so he could shoot a right handed bolt gun in xtc left handed and cycle the bolt in rapids

And holds a national 200 yard sitting rapid fire record, shot left handed, loading with stripper clips, in a right bolt rifle.

This one? One of the good guys for sure, did a lot for the CMP during his tenure.

No
Iirc it was even more funky than that

Next up on this gun is "fixing" the bolt handle. Apparently, it was the test platform for an old XTC shooter and he wanted faster cycling in position, so he made this ridiculous bolt handle so he could just "knife hand" straight up and cycle it. At least that's the theory that was explained to me. ‍

It appears the original handle was cut and this thing welded on, by the discoloration above the base.

I'm trying to decide between cut, D&T for a stud and put new handle on that way. OR, heat and beat this thing straight enough to cut down and thread for a knob. OR, a combination of the two.

Here is a link to a left handed Anschutz bolt handle adaptor that is very similar to the bolt handle design in your picture. I suspect that this handle was made for the same purpose of allowing a left handed shooter to operate the bolt faster and easier.

Well, I might as well use this thread to document the build and progress of this unique rifle. I've edited the title to reflect that.

I made a single shot adapter for it today from delrin, this is a 222 rem, standard length action. For those that may want to make their own, 0.250" thick, 0.625" wide and 2.700" long fits the magwell just so. Chamfer the corners 1/16" or so to get a press fit.

First one I made I added a 5/16" radius channel and because of the flat breach on the barrel, it would not feed, the round was too low. So, used a flat, unshaped piece and it worked perfectly.

This one did not work.



However, just an unprofiled flat piece did work well. I need to contour it to match the action. 1.323" diameter for my action. I have another, rougher condition action I will use as a sanding/fitting guide to finalize the shape so I don't butcher this one.

This is the rough shape of the properly fitted single shot adapter, not profiled.





Will post updates as I go along on this gun.

Nicely done.

I have acquired a rem 788 that has some unique attributes (i.e. customized). Its got a 0 round 6br barrel on it, single shot. My current problem is its sako extractor. It's not snapping over the rim, just pushing the extractor straight back. I have limited first hand experience with this style extractor, and the ones I do have just work.

What are my options for tuning this? Just a couple basic pics.

Obviously, the trailing edge of the extractor is a bit rough, I can clean that up. Do I need to change the angle of the face? Fit seems a little sloppy to me.

Without having it in front of me to inspect I would say time to weld up the hole the extractor pivots in. It may be too large allowing extractor to travel backwards instead of snapping over the rim. I agree it doesn't look like a Sako part but may have been "fitted,altered etc" . Really need to see it first. I have fitted an M16 extractor to a 788 Bolt that had been butchered. It required a lot of time, further modification to the Bolt and imagination to do it properly and I charged accordingly. I don't suggest it unless the Bolt's been wrecked.

As a left hand left eye guy, I appreciate this.

In the video I posted, root cause was a rough finish on the ramp of the extractor. Brass doesn't like to slide on rough steel. Its been polished and functions quite smoothly now. I suspect it is a "shop made" sako style extractor, not a genuine sako piece, or even a commercial equivalent to one. However, it seems to fit, extract, and function well enough for now. I'm planning on cutting and welding the bolt handle in the next month (between other projects) so do expect to see an update on this soon.

Better get after it deer season is just around the corner

Shoot, you know me, I only need a week and a case of good beer to get sh!t done! Lol! (The case of beer might not last a week...)

In reality, I need to finish the restock on the 6brx for pops this weekend and start cutting, welding and gluing on this thing too. Stock work will get going as soon as I can get down stairs in the next few days. Have pillars and bedding material ready to go. Once bolt handle is fixed, gotta choose a scope off the shelf and have 3 bullets to test. All will be with Varget.

As always, looking forward to our antics during deer season, lol!
