5.7x28 FN Bolt action Rifle

I don't know the operating pressures of the 2 cartridges. What type of action is used for the pistol?
That is what I am asking if the action would be strong enough.
 
dicey

winchester lowwall would handle it id wager, anything else id be up in the air about.

plus you want to turn a rim fire into a centrefire, unless its a single shot, you got some major bolt reworking to do.

i wouldnt hesitate to try it in the charles daly little sharps

short answer is no, you cant, but there are exceptions
 
A bad idea (IMHO). The rimfire actions are desined for a cartridge that has (typically) a max psi of 28k. The 5.7x28mm is CIP rated at 50k psi...
 
5.7X28mm

I thought the 5.728mm would make a handy little varmint cartridge when I first saw an empty case at the range and I think it's about the same case capacity as a .22 K-Hornet without having to fire form it. It will be interesting to see if it catches on or gets necked down to .177 or .204. I don't know if it would offer enough difference to be worth the effort and expense over say a
.17 HMR.
 
The 5MM Craig is still very active, thank you IOwolf for mentioning it. We are making a lot of barrels for the TC Contender and a few for the Encore in that caliber.

With the TC Contender you can have the best of both worlds. You can shoot factory ammo when you want and then customized center fire ammo when you want to save money, have a better selection of bullets or a specialized use.

A Contender with a 20 " barrel is a true joy to shoot all day on Pairie Dogs or gophers. No sore shoulder, no hearing loss, effective killing out to 250 or further yards, lots of loads in a pound of powder, did I mention how quiet it is and how often you can shoot feilds that others can't because it is not very load.

The FN 5.7 overlaps with several small rounds.

Compared to factory rounds, it is in the same general area as the rimmed .22 hornet and .218 bee, although both of them appear to be loaded to lower max pressure (although this may be due to the differences between the CIP and SAAMI pressure testing methods).

In around the 1960s there was an attempt to comercialise a .30 carbine round necked down to .22, making it a pretty close match dimensionally to the .22 Kilbourn hornet, but with a rimless case (known as .22 "spitfire and .22 MMJ (IIRC)).

For rimmed cases, a centrefire BSA martini action would make a good strong host, for rimless, a second hand CZ Fox action has proved to be capable of taking the back thrust from .223.
 
I used one of the new Savage model 40's in 22 Hornet, set the barrel back a bit and reworked the extractor. Works like a champ. If I remember correctly the rim on the Hornet is .015 or .020 larger than the 5.7 so we had to do quite a bit of work to get the extractor to function right, other than that it was a breeze.
