Savage coned bolt??

[RWO]

A Savage target action factory equipped with a .223 bolt head will have a feed ramp in the floor of the bolt way that will feed .223 rounds properly. I know, I have one. The standard caliber action can be altered to feed 223 but it takes a long carbide end mill and a special angled guide bushing that screws into the barrel threads to machine the existing ramp(if there is one) deeper thru the front of the action. It cannot be done thru the port because it is too small. It is far easier to find a factory .223 action and just buy it.

I'll bet it won't feed a shorty like my "20 TCM" wildcat.

No matter what you do, the bullet of the "short fat round" hits the breech face before it can get up to the chamber opening.

Except for those running actions designed for them.

I was checking out the XP action and noticed that the loading tray under the bolt is dished so as you push the round forward, it starts to point up and into the chamber opening. That's why it works so smooth.
And I don't think it's the length of the round that makes the difference. It's the design of the loading ramp/tray. Whatever it is, I love it.

A single shot follower is the same way

I believe it's a combination of both cartridge length and follower design. The follower needs enough tray length to take up excess bolt throw while providing a ramp at the proper forward location to "nose up" the round based on the cartridge's base to shoulder length. They work in unison.

If the action was made for a .473 casehead cartridge, it will feed any .473 casehead cartridge just fine. Same applies from magnums to rimfires.
No tuned ramping needed there.
But otherwise, ramping can get you through the day.

This is a Savage single shot short action and it WILL NOT feed the short round. The ramp does not point the round UP and INTO the chamber like a Remington XP 100 action. The bullet tip hits the area of the barrel face around the chamber when the bolt pushes the round forward. That's why I was considering a "coned bolt".

Well it obviously was not designed for "the short round" (your round).
You had this notion earlier: Now I need someone with a XP 100 pistol in .221 Fireball that wants to trade for a Savage bench gun.
This was at least a path to solution, but I doubt anyone with such a configuration would take the trade.

I think this idea of yours has hit an end

I think this idea of yours has hit an end??

Sorry Sir, you are sadly mistaken. Already talking to someone about maybe trading or even buying an XP out right. Patience is a virtue.
May not work out but then,maybe it will. Only time will tell.
And there's always this thing called CASH that comes to mind.
Works for me.

 

[mikecr]

That is great. I'm sure it will be a fun build

A cones Savage bolt head would be a great little upgrade. Especially for single feed actions. You guys have me thinking now. Would not be to hard to manufacture them. Another thing to add to my development list.

The only thing with setting the head space is if you can get close enough and still support the case. And you can only taper (cone) the bolt head so much and still have room for the extractor to move. Lots of R&D involved. But if you never try, you'll never find out if it can be done.
And for those folks thinking, Savage didn't chamber a 10 or 110 action in anything close to a 22 TCM or even a Fireball.
Went thru this with a .221 Fireball. Single fed with no problem till you pulled the bolt back on a fired round. Short brass pops off the bolt head before it clears the port opening. Cured that by removing the ejector rod and spring. Brass stays on the bolt head till you pick it off. No chasing brass that way either.

If you started from scratch you could angle the extractor like the Bat. I'm guessing that is what Grimstod had in mind.
