The biggest draw back I see is case forming. It will take several steps to form the brass and be a real hassel. It` no where close to the .17 Rem. in velosity and if your wanting a slower .17 cal. round the .17 Mach 1V will still out do and if you want still less the .17 AH will do almost as much but the brass for these round is much easier to form. I shoot 3 different .17 cal centerfire rounds. The AH, the .17-223 and the Rem. The 223 round is almost as worthless as the Javilian, as it is so close to the Rem., but brass for it is very easy to form. I bought it in a Contender barrel with dies included for about 2/3 of the price of the barrel alone, IT WAS CHEAP! Putting that round in a carbine will give you a fast fireing varmint rifle, but accuracy will not be to good unless you spend alot more money on the gun to have it accurized. It would probibly be cheaper to trade your rifle on a Ranch rifle and have it rebarreled into .17 Rem., but if your wanting an accurate gun you would still have to have it accurized. To have youe gun rebarreled to the .17 Javilian will cost about $ 300 for barrel instulled and form dies will be over $100, plus if you have the gun accurized it will be another $100. If you`ve never had a wildcat rifle befor this would be a bad one to start with for 2 reasons. 1. Case forming is so involved and 2. your putting it on a semi-auto action.
That`s my thoughts on it, but right now I`m haveing a .22-6mm built for a long range gun and there are alot of people who see no use for it, but case forming will be easy and an 80 gn. .22 cal. bullet has a very high BC and wind drift is about 1/2 of most of the factory rounds used for long range shooting. It all boils down to what your will to pay for something about no one else would want and prospecs of selling are poor.

Thanks Catfish this is the kind of info I'm looking for. You have raised the POWER & COST factors which I tend to agree with,
first the universal has no gas blowback (SPRINGS) and I wasn't sure they could handle it without regular replacements. Second again I realize caseneck wall thickness is a major problem time wise. I suppose the mags lips would have to be readjusted also.
I'm still considering though. Much more like this and I'll be swayed
to enter a different realm. Thanks again Catfish!

Least you be concerned about conversion, I was just readin about the carbine conversion for the 502 Thunder Saber.... a 50A&E case with the rim turned to the deminsion of the 7.62x39.

The 17/30 Carbine is an existing wildcat as is the 22/30 which was a popular kit conversion item in the 60s.

frankly, the commercial .30 carbines are suspect for any conversion work, and a USGI carbine is worth too much for foolishness like this. The last gun show I was at had them going for over $800. The days of cheap carbines to play with are gone.
