Perhaps 4130? Basically just less carbon than 4140.

When we take our prototype bolt back to them next week to log the changes and get the first run made we will get them to slow down the machine shop lingo so we can tell what the heck they are saying

According to pierce and 7mmfreak we really don't want ss if we are expecting any extra protection in the event of a failure. Even the ss remington actions have a CM head on them, if you push a ss action too hard the lugs setback into the action.

Doesn't get much prettier than what their cm's finish out at either. No coating is required as long as you don't majorly neglect them but ss will rust if you abuse it also.

I assume this setup will require headspacing by a gunsmith? I wonder if its possible to have an adjustable barrel nut on a Remington action/barrel rifle. If I missed something in what you are doing Iam sorry, just curious, Ray

The first bolt/barrel prototype will have the head spacing set. Just like the 700 ML. (Pretty please) Screw your brux barrel with the Arrowhead plug onto the Remington Ultimate action, put your Kash/Myers bolt in and go shoot a 1/2 MOA group at 500 yards.... No head spacing required, I hope. Am I right?

I don't think the remnut barrels are the way to go. I am hopeful that I can take about 6-10 actions and come up with a "prefit" dimension that will be headspaced the same way we do 700mls currently. There should be a good balance point where this can be done successfully. The best fitments of course will come from sending your action to be custom fit or having your smith of choice do the work.
Yes Earnhardt is right, I think if you want to go for 350-425gr bullets at 3,000 fps or better you should have it fit for your specific action to ensure the crush on the primer nose is spot on. This pertains to Earnhardt and all the other loose nuts!

Don't need to...my 416 barrel with the Arrowhead plug is a pre-fit...works great! Yours can be the same.

Good to know Earnhardt, reports are still few and far between for the new plug and we should be able to replicate those results! If they spent the time to get the 700mls that close the CF's will be at least that good.

Cole,
It is very possible to make a prefit for the Remington 700 actions as long as the actions haven't been modified.
It is nice to have the crush fit on the bolt end/ breech plug end but not IMO not totally necessary. There is a window of around .010 or so and most UN MODIFIED Remingtons actions I have worked on will be within that window.
Your bolt is impressive and very well made...will be an absolute perfect tool for those who want to use 209's in a centerfire action or want to have the option of a switch barrel rifle.
Well done!!!!
Mike

I keep reading about the "crush fit" with all the 209 plugs and bolt noses, it needs to be carefully done. If I remember right, Richard set off some primers with a "crush fit". We put the primer into loaded barrels, possible bad news. Changing primer brands could also come into play with this. Granted, we have been doing this pretty much all along, just be very careful.

I aggree....been wondering when someone would bring this up. I polish for a nice snug fit but no "crush" Drop

Ok crush might not be the appropriate word but is think you guys know what we are talking about. I'm shooting for a .001-.003" interference fit with the nose, I know it's not going to cause a problem. Has anyone but Richard set one off this way?? The primer cup is set down inside the body a decent ways and a few thou isn't going to even touch the cup. Drop, you already have a arrowhead plug correct? Chances are if you didn't headspace it yourself, you've already been shooting a crush fit plug.

When I think of crush fit I think of an Ackley chamber for a rimless cartridge. Those chambers engrave a visible line at the neck/shoulder junction. My muzzleloaders don't have that sort of head-space and shouldn't since you are crushing a fragile vessel full of explosive. All of mine are tight and fully supported but when I chamber and remove a primer there is no visible marking like a crush fit would leave.

Chances are if you didn't headspace it yourself, you've already been shooting a crush fit plug. . My smith set the head space roughly . Then I polished the primer pocket with 500 grit paper . This took about 8 times of this procedure to get the primer to intreface properly. You're right "crush fit" isnt the right term. This can very easily mislead some folks.Only richard that I know of has had one go off....BUT it only takes one. My primers come out perfect. It only takes about 45 min to do it this way.I would hate to se someone "overcrush"one and have an accident. Not being critical....just careful drop

Careful that we are talking about two different things here.
Headspace and primer fit are not the same

Mike when you headspace ....how far do you space the face of the bolt away from the plug face? Drop

Russell,
Hard to get an exact measurement because of the angled end of the breech plug fits inside of the bolt nose.
If installing a barrel, one can seat the plug a little long and screw the barrel down to where the bolt and breech plug touch then take a measurement between the action and barrel shoulder with a feeler gauge then cut the measurement plus .003 or so.
I try to make the breech plug touch and then back off a few thousandths so the two are very close but don't touch. In center fire headspacing you have to hit an exact point 1 -2 thousandths off the go gauge but there is quite a bit of leeway with the muzzle loader.
There are differing opinions but I personally don't like for the bolt and breech plug to touch.
You are not going to be hurt if the gap is .010 or so and this is why I think it would be feasible to make pre-fits for center fire rifles with the Meyers/Kash bolt and the Arrowhead plug.
Your head space is set exactly the same as Lukes Brux barrels and arrowhead plug combo that he offers and was worked out by hitting a comfortable average from measuring several ml actions.If the need were to arise, you could screw on one of his barrels and plug combinations and go shoot.
It is possible to pre-fit Savage target actions as well and has been done already.
Make any sense?
Mike
As an after thought, the tght primer pocket is NOT a crush fit nor should it be.
'nuther after thought, the prefits work as long as you use the standard .187 recoil lug
The Savage target actions prefits are done like Remingtons with no barrel nut.

Guess that's a real crush fit and still no boom. Pretty much proves that the primer has to be hit with the pin to cause ignition.

Cole,
Crazy test but good
Still got your eyeballs and fingers? :-)
You and Earnhardt need to get together....maybe, sorta, kinda....
