Looking for anyone that has experience with this cartridge in an M1 carbine. It is the .30 carbine necked down to .224. It looks interesting enough, I just would like to hear from some of you that either have one, had one, shot one, knew a guy that shot one, saw one shot, or heard about somebody shooting one. I am contemplating building one, but won't waste the time or energy if the collective experience is negative.

many moons ago I had one of these. It was kinda fun to play with, but very tricky loading. a couple tenths of a grain of 2400 would make the difference between a decent load and blowing the primer. Its to long ago to really remember, but I think the load I used was something like 8.8 grains of 2400 and a 40 gr hornet bullet. accuracy wasn't much beyond 4" or so at 100, but it was a blast to shoot rats in the dump with

I've got one that I use for shooting prairie dogs. Really like the cartridge. Very mild report (not much more than a .22 rf), accurate and inexpensive to shoot. I have fond that I can shoot 500+ rounds a day through it at prairei dogs with very little fatigue. My gun is an older Rem 700 ADL action with a Shilen barrel. I don't have my load data here but will try to post it this evening when I'm home. If I recall correctly I'm pushing 3000 fps with a Remington 45 grain hollow(soft?)point. I've had no probelms with pressure signs. I can't recall what powder I'm using but it is one of the loads listed in Cartridges of the World. I have run in to some issues with necks splitting either on initial sizing or 1st reloading. However, .30 carbine brass is cheap and I was able to size down to .224 in one step with only about a 2% loss rate. Loss rate from split necks from firing and / or sizing to reload has run about another 5%. I could probably solve the problem by annealing, but haven't decided if it's worth my time given the low cost of virgin brass.
