Looking for something in .25 acp or 5.7x28 to have a tailorable reloadable .22 lr in essence. I have found the following in my searches.
.25 ACP most people think it's a joke a few pursue the idea but never post anything conclusive about the finished product or how it performed.
5.7x28 all I can find available are butt ugly black things that look like they belong in a sci fi movie.
I suppose having a custom made contender barrel made is always an easier option, if you liked contenders.
So what are one's options apart from stubbing a H&R shotgun? Remove the lug on a .223 barrel, cut back and rechamber and re-attach the lug? Just looking for options here and it doesn't necessarily have to be a single shot either but I figured that would be the most cost effective and simple route.
I know you can download .223 to .22 mag and even lr velocities but I don't want to hassle with using filler etc. I'd rather hassle with building a unique rifle instead.
