rebarelling and feeding question

[inthebeech]

I have a commercial mauser (Husky) in 270 Winchester that I'd like to have rebarelled to 22-250.
To try to get an idea how well this medium action will feed and extract the new case, I purchases and fed some 22-250 rouonds; they fed just fine, popping out of the magazine and up under the extractor exactly as the 270 cases do. However there is a brief instant with the 22-250's when the bolt loses full control, the case comes back out from beneath the extractor, and I can pul the bolt back without it having control over the case. They still go completely in to the chamber just fine, it just acts like a push feed action from about a point when the bolt face is about a half inch away from disappearing in to the receiver ring.
My question is whether the fact that the chamber is not correct might be partially responsible; will the action truly behave as a controlled round feeding action again when the approproiate 22-250 chambered barrel is installed or do your (I am speaking hopefully to gunsmiths out there) customers just live with a push feed action? Further, if this is the case then how is durrability affected when now the claw extractor is going to be snapping over the case as opposed to the case slipping beneath as it was designed to do?
I do not want any alterations to the metal. I may go back to the 270 chambering some day and the action is too beautiful; so any of the more extensive rail or extractor modifications are unacceptable. If they are typically done with a rebarelling job such as this, I will just go purchase a 22-250 rifle.
Thanks,

Going from a long action round to a short action round in itself can create feeding problems, as you are aware. I certainly understand not wanting to modify any components of the action.

I have actually done this conversion myself on a standard M98 action without any mods except installing a single shot Bench rest follower in the magazine. It functions well, and I have no need for running ammo through the magazine.
Here's a link to a follower like I have.

just put a spacer in the back of the magwell and you should be fine.
i've used plastic, aluminum, steel and horn for spacers.

I have done this caliber conversion on several standard M98 actions. My favorite way to set up feeding for the 22-250 is to install a short action magazine kit. This kit consists of a back magazine spacer and a shortened spring and follower. Sometimes it has been necessary to replace the extractor with an over-sized aftermarket one to allow more positive engagement with the cartridge rim. These modifications can be done without permanently altering the action. and the original parts can be retained if you would want to convert back to a long action cartridge in the future.
