5.7x28 bolt action

Post by turbobrick » 01 Nov 2008, 19:56

We all have seen that FN announced they would bring out a bolt rifle in the 5.7x28 chambering. Its been over two years since they announced the rifle, I wonder if you all think it will ever come.

Now, Brownells is offering a Shilen barrel for the Remington 700 action. I am a big fan of the 700, and would love to have one in 5.7. However, I don't know enough about custom rifle making to know what I don't know. From my research, 17 Fireball is the closest to 5.7 that the 700 is currently chambered in. The Fireball has a very similar overall length (about 6mm longer), but is about 1.6mm larger at the base. Is re-working a bolt for a new chambering something that is easily and commonly done? If so, roughly what kind of cost do you think would one be looking at?

The cheapest 700 in 17 Fireball I can find is in the $450 range. So add the $260 barrel, bolt work, barrel fitting/chambering, etc, and this turns into a project that could cost more than even FN's elevated pricing. If FN is really going to bring it out, I would rather pay a little more for an off the shelf solution. Thanks for your opinions.

Try Midway for the bolt http://www.midwayusa.com/esearch.exe/se ... l_products" onclick="window.open(this.href);return false;

I'd be more worried about a workable magazine, or winding up with a single-shot bolt gun.

From everyone I've talked to a workable magazine or magazine adapter does not exist as of yet so your nicely converted rem.700 will be single shot only and for 2-3x the price of a TC contender or Encore.

As for the FNH version, I'll believe it's being released when me shite turns purple and smells like rainbow sherbert.

The day that happens though, I better have a lot of money set aside as I'll have a lot of commitments.

Well hell, I didn't see the bolt there. That looks like my biggest concern isn't really an issue after all. So any short action plus the barrel and bolt, plus my gunsmith equals a functional 5.7x28 bolt action? If so, I think I'll dive in and get it built. I think I can work out the magazine thing with a little work.

Let us know if you do. A custom follower wouldn't be that hard to fab up. You'll want to get the rest assembled and get a mag of something that is as physically close to the 5.7 as possible, primarily in case width, take the factory follower, fill it with epoxy then use a dremel or small grinder to re-shape it as necessary, and go from there.

My point of view,

Why not just get a .223? Same projectile, more powder. I understand the purpose of the 5.7x28 as a PDW and pistol round, but if you are going with bolt action, why bother?

If you really want to get creative get a license to make a full auto Five Seven. Then find out how many 30 round mags it takes before the plastic bursts into flames. Oh yea, and don't forget to post it on youtube! :lmao:

Do I smell a Troll?

Either way, if you don't believe in doing things just because you can, you're only going to enjoy about half of what firearms have to offer.

Because its nice to go to the range and only have to worry about bringing the same type of ammo for pistol, PDW, and rifle?

I have several .223 rifles, and I just don't need another one, especially a bolt action. My collection is pretty well balanced, and I would like to get some more interesting items now that the basics are taken care of. I enjoy the idea of sharing a round in rifles and pistols. Since I sold my 17 HMR, I don't have a good varmit bolt action. So, if somebody is making barrels and bolts why not make a rifle in one of my favorite pistol cartridges? Think of the velocity possibilities with that 24" barrel and some well researched handloads. The search is on for a cheap short action 700. I'll keep you updated, thanks for all the help.

The 17 Fireball is really close in length, the guys at Sportsmans Warehouse said I could try my 5.7 rounds in their 700 in 17 for fit. We'll see how it goes.

17 fireball is a necked down .221 which is a shortened .222 which is what the .223 is based on. Length is close but diameter of the case is quite different, which could cause feeding problems. Length isn't as important as diameter, if the diameter is off the bullet isn't going to center properly at the top of the magazine and it won't feed right. IMHO at least.

Well I was thinking that the magazine block for the 17 fireball would be a good start to making it feed well, another follower might be a better fit diameter wise if cut down to the 17 block.

No troll, that was a serious answer. I thought the purpose of the 5.7x28 round was to create pistol ammunition with the characteristics of a rifle round, for use in PDW and pistol platforms. That it does well, but if you are going to use a rifle, why bother? I would just as soon use a cheaper, more common, and more powerful rifle round to do the job. I see the point of a 5.7 AR upper for those that already have an AR lower, and hell I would love to see the video if you were to make a miniature belt fed 5.7 SAW variant or Gatling gun or something (they have done it with .22lr).

Don't get me wrong, I'm not saying don't do it. I'm just saying for any practical purpose I don't think its worth it. It's like hearing someone say they are going to drop a 4 cylinder VTEC engine in an older Dodge Charger. The VTEC works great in the cars its made for, but the Charger would benefit from the much larger V8 engine than it was made for. The conversion required to under power it seems a waste.

Ok you have me on that last point

I admit I see things a bit differently, I don't want a PS90 because it would eat up all my best pistol ammo! Ok I admit it, it would eat up the Five Seven ammo, but I still want a PS90. :drool:

I do see your point but, try not to think of it as competition for a riffle round in a riffle, try and remember that the round was designed for a pistol/pdw combo. Think 9m riffle compared to 5.7 riffle to understand the appeal a little better.

OK, I talked to my gunsmith, and I think I've got it figured out. He dislikes working those custom bolts into a rifle when he can more simply machine, bush, and fit the original bolt. On the barrel front, he wants to use any 700 barrel bored and rifled for .224, then he will chamber it for 5.7. I'll figure out the magazine issues at a later date. So, after I find the right 700SA (most likely 17 Fireball) and a good raw barrel, the build is on.

Good Luck, let us know how it functions and the cost when all is said and done.

I'm just wondering,and I've been trying to see,if a mag for a .22 Hornet would work? my shop has some and I may try to see if a Hornet will be a close fit.

A bolt 5.7 with a 16 or 17in bbl and iron sights with a small scope/dot sight would be rather nice.
