Re: 5.7x28 bolt action
I've thought that the Ruger 77/22H might make a decent starting point. The rotary magazine shouldn't require any mods. A box magazine probably would require some changes, but I haven't fiddled with any.

Re: 5.7x28 bolt action
I can understand liking to play with rifles but if you already have a 77/22 in 22 Horney why spend all that money and time to basically duplicate the same ballistics of the Hornet while making it harder and more expensive to get ammo and brass?
Kind of sounds like an excersize if futility or an answer to no question.

Re: 5.7x28 bolt action
It's not really more expensive. .22 Hornet can be pretty expensive. I think the PRVI is like 20 bucks a box of 50.

Re: 5.7x28 bolt action
Actually, the point is that I (and most everyone else here) already have a source of lots of 5.7x28 ammo and brass. I don't have currently have anything in 22H, and I don't really want to deal with another cartridge (which the 22H would be, for me.)ladderstand wrote:I can understand liking to play with rifles but if you already have a 77/22 in 22 Horney why spend all that money and time to basically duplicate the same ballistics of the Hornet while making it harder and more expensive to get ammo and brass?

Re: 5.7x28 bolt action
For me, its all about consolidating caliber. If I can carry a handgun that I really enjoy, and have a lightweight, accurate bolt action that gets even more velocity out of an already speedy round, I'm happy. Just look at the numbers EA is getting out of the FiveseveN, now think about the potential performance from a 20" bolt gun. I don't understand all the talk about expensive ammo. 5.7 costs less than brass cased .223, and is much less than .17 Fireball, the donor rife I plan to build my 5.7 rifle from.ladderstand wrote:I can understand liking to play with rifles but if you already have a 77/22 in 22 Horney why spend all that money and time to basically duplicate the same ballistics of the Hornet while making it harder and more expensive to get ammo and brass?

Re: 5.7x28 bolt action
Very interesting! how about an update? even though i think id go for at least 20" maybe even 22-24" barrel as for ps90 is 16 so you already know the basic ballistic capabilities!!im sure you would,or have,achieved 4-600 fps faster ?????
Re: 5.7x28 bolt action
still no update on wether achieved? 

Re: 5.7x28 bolt action
I would question whether the 22-Hornet produces the same ballistics as the 5.7x28. Most data I see for the Hornet is out of a 24inch barrel....and yet they are almost comparable to 5.7x28 out of a 16 inch barrel. I'd be very interested to see what 5.7x28 would do out of a 24 inch barrel....unfortunately the main advantage of the 5.7x28 is excelent performance out of a relatively short barrel....so not too many people want to do that.
I will have an 18.5" barrel shortly (its been 8 weeks now). In retrospect, I wish I would have gone a little bit longer w/ it. Logic would dictate ~125fps improvement over the 16" PS90/AR57...however, the T/C is not blowback, so I should be able to push it a bit further.

Re: 5.7x28 bolt action
I think you might even think about necking the 28 case down to either .17 or .20 cal. That should give you a really interesting round. What you would end up with is something a fair bit quicker than .17hmr and 5mm magnum rimfire and definetly more accurate. The costs for running the 28 case will be on par with buying that rimfire ammo. This may be what occurs. All remington short actions are the same length. The magazine is a bit of problem as it is internal. If you had a drop out mag you would be able to put in either a follower or a stop at the front to keep the rounds feeding properly. This project is something I am considering however at the present there is not enough info on it yet. The dies have just appeared over here but we will have to wait until somebody produces a rifle as pistols are banned over here. I will be interested to see when the bolt action rifles come out.

Re: 5.7x28 bolt action
Google "17 Velociraptor" or "20 Shrike" 
I suspect that Calhoon's .19 caliber bullets would be just about perfect for this case.

Re: 5.7x28 bolt action
While a 5.7x28mm Bolt Action would be nice, I see it as an answer to a question that hasn't been asked. At this point in the .22 cal and under category, I dont think a ruger .204 can be beat.

Re: 5.7x28 bolt action
Update.
Sorry for the delay guys, I was holding out for FNH to step up and sell one, but another SHOT come and gone with no love. So, I ordered my barrel, reamer, gauges, and stock this week. The action goes to the smith this week for blueprinting and bolt conversion. Unfortunately, the barrel lead time is almost comical in its length, but I'll keep you all posted.

Keep us posted!
Out of curiosity, what did you specify for the barrel? Twist? Chamber specs?

Re: 5.7x28 bolt action
I went nuts. Its a Krieger in the Remington varmint profile, 20", fluted, threaded for 1/2x28 break, 1:14 twist, with no chamber. My smith will do all the chambering, one the barrel arrives, some time after pigs fly.Esteves wrote:Keep us posted!

Re: 5.7x28 bolt action
Good choice on the barrel, keep us posted, if you figure the Mag thing out I might just have to build one up too.turbobrick wrote:I went nuts.

Re: 5.7x28 bolt action
Well, the barrel arrived on Wednesday, and the whole box of parts is at the gunsmith now. Its his busy season, so I'm not too optimistic about getting the finished gun back soon. However, the barrel looked absolutely awesome. I'll definately be picking up another Krieger, if the barrel prints half as good as it looks. The gunsmith, who has been building guns longer than I have been alive, was really impressed with the finish, especially the fluting. He wasn't too excited about working of the magazine, so it'll be a single shot until I get it back and can try to figure it out.

Re: 5.7x28 bolt action
I agree about the pics, but I felt it more important to get the barrel in his hands before he closed for the day. I went straight from UPS to his shop, and just beat his closing time (he has crazy hours 6am-2ish). Tons of pics to follow when the thing is finally done.
Re: 5.7x28 bolt action
I am with you on this. Though I am personally planning on building my own gun from scratch. I may even go as far as making my own action. I know I will be profiling the barrel. As to those who ask why do it, my answer is twofold. One, because I can. Two it would make a neat suppressed rifle with high velocity bullets that would really do a number on varmints, especially with a can. I think a bolt gun would be more accurate than the semi autos. Also I want a gun that uses common ammunition with my other guns, magazines too when possible. So my project profile includes using a FiveSeven magazine well probably to be machined from aluminum and fitted up to a stainless action. I must start to say that I have NOTHING written on paper other than objectives. No dimensions, no sources for prefab parts or shared info from other people who have done this before. So if we can work together maybe this can get off the ground, what say you?

Re: 5.7x28 bolt action
I'll share any info I can provide. I'm also more than happy to loan out my reamer and headspace gauges once the gunsmith is done with them. I was also thinking about trying to adapt fiveseven mags, we'll see once the action is barreled and the H-S Percision stock.
