Sorry Pete.....didn't see where mentioned a twist in your earlier post. Thank you sir....9 it is then. Waiting to here back from Short Action Customs. I'm excited......almost as bad as Ralphy getting his new Red Rider on Christmas day.

I'd go with the 17MIV / 17FB. It does about the same as a 17Rem but with a lot less powder. Mach IV 25gr working loads are 3900-4000 depending on powder. My MIV's are on small Sako actions but years ago I converted a 700/.223........after modifying the spacer, spring, and follower it functioned beautifully with a standard small boltface.
I have .17 barrels from Shilen, PacNor, Douglas, Wilson match, Lilja, Montana Rifleman, Pence.........they're all good.

Yea,,,, same bolt face, just shorter.
The shorter case tends to eject before reaching the ejection port, flips around backwards, and remains in the magazine of standatd 700 actions.
Some modification's work, and some don't. Even the relocation of the plunger that Remington did when they introduced the 17FB isn't always reliable.
A small action like the Sako Vixon or CZ 527 would be my choice for a FB/MK4.
Matter of fact, that's exactly what I did.

I don't have a Mach IV or 17 Fireball any more. I do have a Rem 700 Classic 221 Fireball, and a CZ 20 Vartarg. Also a neat little round. If I were to build another 17, I think I would stay with the 17-223. None of the problems with feeding, finding brass, or ejection of spent shells.

The short Sako 461/AI action is perfect for a .221 length case. Also it has a fixed ejector which is nice, and works flawlessly. For that chambering Remington altered the ejector position. The Remington ejector springs is strong enough to throw a case 10'. Weaken the spring by making it shorter.....I cut them down to where the case will just plop out and fall next to the gun. It makes a 221/17MIV work fine with the std. 223 bolt.

So which is it? Spacer, spring, and follower? Or just spring.
Back to the real world,,,, small actions for small cases is a pretty good rule of thumb.
Sako extractor is nice but CRF is fool proof.

Maybe I'm not reading this right, but I think that when Ackmann is talking spacer. spring, and follower he's talking about feeding from the magazine.
When he's talking just spring, he's talking about the ejector plunger spring.
Two different springs and two different functions.

The solid follower was reshaped a bit. An ADL .223 spacer was reshaped to extend it. It's been about 15yrs, but I think the ends of the magazine spring were shortened a little also. And for every chambering the ejector spring gets shortened anyway, those things are too strong and throw brass all over the place.

I agree 100%,,, especially if you're using expensive brass in tall grass but I'm convinced that timing,, not spring pressure,, is the culprit.
Either way,,, having an action that's sized for the cartridge is the easiest way to solve it.
That's why they make micro, short, long, and magnum length actions.
Heck, even Tika's infamous one size fits all action has problems with super short cases.
PS,,, my single stack, controlled round feed CZ cycles FB sized cartridges flawlessly.
