You Idaho folks or folks who may hunt in Idaho may wish to visit the Idaho F&G site and provide input on their technical survey. i.e., limiting calibers to less than 50. ID F&G
The 16# limit is enough to do what they wish. [img]/ubbthreads/images/graemlins/wink.gif[/img]

That's what I thought.
I thought my 338 Lapua was pushing the limits on cart. dia.
I think you would need to do some engineering on the toggle to get the breach low enough to load that large of a cartridge as I think if you mill down the breach block enough to insert that large of a cartridge you would leave part of the brass exposed. I think you may need to also machine down part of the top of the action to get that large of a cartridge into the chamber.
I would think that Kirby has thought about how he can accomplish all this or he wouldn't have posted such and am interested in how he believes he can do it .
If it can be really be done I am really interested as I have a Ruger #1 7mm Mag that wants to be something else.
Another thing that concernes me is the holes needed for the scope base and weakening the barrel drilling them. If memory serves me about 1.2 is about max for the tenon unless you redesign the firing pin spring/forearm hanger.
Then again maybe Kirby is just toying with us to see if we are paying attention.
Kirby?
I have seen several custom #1s in chambering such as the 505 gibbs, 500 Jeffery, 500 nitros, 577 nitros and even 600 nitros. I believe the case head of the CT is the same or smaller then these.
It may not be wise to load it up to full pressure but I suspect in a 10 lb rifle most would bend to the recoil before you got into pressure problems. Strength wise, the Ruger #1 is as strong as any bolt gun, its extraction mechanism is relatively week but it would take a serious force to move that breech block when locked up.

How big exactly do you think the rim diameter of the 408 CT case is??? My TTI cases are 0.635" in diameter at the head and rim. A 338 Lapua has a rim diameter of 0.590" so from center the 408 CT case is only 22.5" larger in diameter so it is not dramatically larger.
Taking some quick measurements on my #1, all that would be need to chamber a round of this size would be to slightly increase the bevel on the rear section of the top locking block and also slightly increase the depth of the bevel in the receiver behind the locking block.
No widening would be needed at all as the 50 AT case lays perfectly in the feed way as is and only needs to be lowered by about 30 thou at the very most. 5 minutes with a properly size carbide round end mill would solve that issue.
I do not think it would as big of an engineering project as you may think. Only real issue would be safety with the pressure capabilities of the 408 CT case. Again, recoil would reach serious levels far before you ran into the pressure limits of the rifle I am plenty sure of.

I would think that getting #1's to consistantly shoot in the sub 3's would be the hard part. If you can't do that there is no need to make a super long range gun out of one. I guess it depends on how hard you want to work to make one shoot.
Yes i supose it will work as long as you load the cases light, all the cases you listed are low pressure rounds (45,000#). I wouldn't want to be behind it on a full tilt load. Shooting the 408 or its wildcats can be deceiving, we talk about low pressures on the loads, i tested a 408c-t with a strain gauge. I was shocked to see what the pressure was on warm loads. When the case was tight to extract the case pressure spiked to 81,000# The first load to extract with ease was 68,000#
Personally i would never build such a rifle, if the wrong person got ahold of it and got the wrong shells, one load for the bolt rifle, it could be a major disaster. "This is just my opinion"
I'm sure the action is plenty strong for normal mag cases, ie 458 win and such. There are design parameters for barrel size, tennon and case dia that should be followed.
C-T case barrel shank, cr-moly barrels 1.350"min
Stainless barrel 1.400"min
If you turn a 1.062" tennon onto one of these barrels, your wall thickness drops below safe levels, heading into murky waters.
If one was to do this i would make the chamber so the bolt action loads would not fit into the chamber, make it a bit shorter.
You missed my point concerning the purpose of the #1. It would be for a close range heavy dangerous game stopping rifle, nothing at all to do with LR shooting in any way. I would even leave the rifle with open sights in the tradition of a true African Express rifle.
Bullets used would be in the 525 to 635 gr Round Nose Soft Point or FMJs.
Again, I was talking about two completely differnet purposes for this chambering, one as a long range preceision rilfe, the other in a short range stopper.
Its not hard to make the #1 into a minute of cape buffalo rifle.
