Bolt shroud gizmo

[WSnyder]

the bolt handle turned the shroud screwed into the bolt body to the point where the gap between the face of the shroud flange and the back of the bolt body was almost nonexistent

That's something I've thought about but haven't done anything towards it. All it would take is another order to McMaster to get some shims coming. I suppose I could easily turn a shim out as well. Not sure if there'd be a gain over and above a fitted Speedy style shroud but who knows? Probably need to check back surface of the bolt.

On a Rh Rem. Action, the shroud screws out as the bolt is closed.

Yeah, that wont work. Doh

I just finished making a shroud for a Panda. I used the delrin af. I cut the threads for a snug fit, turned the area for the thread relief in the bolt for a snug fit. When I set up to cut the flats and cocking piece slot, I ran the piece into the bolt to contact the shoulder, then backed off about a 1/8 turn, then marked the location. Came out great.

One thing to consider about a plastic shroud, safety. In case of a catastrophic case failure you might end up with a face full of firing pin. Somewhere on my old computer I have a picture of Jackie's old Farley, with the bolt closed, looking from the port side. The bolt body has a series of large holes all the way down the side through which you can see the firing pin and spring, I never asked him why, but one thought came to mind, which was gas venting, for safety.

"a face full of firing pin...."

It'd be nice if the cortina bits came oversized.

You can get them in .502 or .510. The PTG 'Speedy' shroud is .550, I believe.

I got one of each of the Cortina to have in the shop. I didn't realize the Speedy version was something you could still get. PTG says they're in stock

Impressive skills, Wayne!

On 700's you're assuming the treads in the bolt body are true.

exactly, or even benchrest actions. so now who knows how to fix it

How did it shoot, range report please?

Haven't shot it yet. Was supposed to shoot yesterday but was cancelled due to weather.

Don’t know which came first, but Wichita actions (early 70’s) had left hand on RB, and right hand on the LH actions. And threads fit very well.

Tim, I still have one they fit very nice now if we could just get somebody to start making them again....

As you know I did for awhile. Moved to KC area and sold the Wichita and Champlin to a couple of guys in Texas. Apparently not progress from them yet.
