We were discussing the idea of a "Ruger 10/22 configuration but done in 5.7x28. Any thoughts.

sounds like a great way to blow your head off, the 10/22 couldn't handle the 22 mag, so what makes you think it would take a high intensity round

Let's see Ruger had to go to a steel reciever to handle the 22mag. Which happens to operate at about the same pressure as the 22LR in the 24,000psi range. So stick a cartridge in it that operates at twice the pressure. Not me.

I thought I remembered some automatics having issues with the 17wmr. Spliting cases or something.

I'm aware you are unable to convert a 10/22, that is why I used the word configuration. It would have to be a different/new weapon entirely. Perhaps I posted this in the wrong forum as well.

A light semi auto carbine in 5.7x28 more likely something like a M1 carbine instead of a 10-22. would be fun. At 4 or 5 lbs with 20 round mags I could see it.Sty stock stainless steel.

The rest just read 10-22 they jump the gun to say the least.

Welcome to AR

I see a mini-14 or maybe even a Ruger 44mag carbine as a better starting point. You need some type of bolt lock up to handle 50,000psi.

Gee, forgot all about their old 44 mag carbine. That's the idea. Maybe they'll do the ranch rifle in that someday. Not gonna hold my breath on that one though.

I really like the consept of a light & handy semi auto carbine in 5.7x28. Just need to design an action around it. Interesting. It would make an awesome suvivial rifle especially for a bush pilot with the weight limitations. Could carry LOTS of ammo!

you intrigued me. Not sure if these are vaporware or in production. Or if this is a configuration that interest you. http://www.excelarms.com/newproducts.html

Wasn't aware that they had receiver problems. One of our AR members manufactures 80% receivers that are set up to do any 17HMR2, 17HMR, 22lr, and 22mag. Basically you drill the receiver for 2 different positions for your trigger group and he has tungsten bolt for the mags as it is a lot heavier. I have one that I have not finished.

Butch you got my attention. how do i find those receivers?

You might send a PM to aleaddict. If no luck I will try to find his email address.

K Thanks.

I have shot the FN P-90 (full auto), kind of a neat toy. I guess the FN P-99 (semi) is not to your taste. It is too expencive for me to want.

For me I will take a 22 Mag or a Hornet, for this class of weapon.
Everything is already out there, guns ammo etc.

It's not the receiver or the barrel strength that is at issue here; it is the fact that 10-22s, and all semi .22s, are blowback operated, meaning that the mass of the bolt holds all the backward pressure; then the brass case and the bolt travels rearward. You can make anything work like that, without a locking mechanism; you just need a really heavy bolt to do it. Look at a Sten gun, for example; it fires very hot 9mm ammo, but the bolt weights about 3 pounds. So, if you chambered a 10-22 for a high pressure round, you would get lots of gas released into the action, (probably blowing out your magazine) while your bolt would be traveling at a very high rate of speed toward the rear of the receiver. Eventually, it would batter itself to pieces, and....it just won't work.

That is why Brian uses a tungsten bolt{weight}
