I bought some of what I think are the bullets Armscor is making for reloaders of the .22 TCM, 500 of them off of Gunbroker. I'm a .22 Hornet fan, but have stuck to cast only in it. Might try some of these in the Hornet, but was mainly interested in how they'd do in the .222 or .223.

I have two rifles in .23, one from the 80's which has a slow twist and a Mossberg MVP which I haven't checked, but I suspect has one of the fast twist rates popular nowadays. I'm sure the old .222 is a 1 in 14" twist.

Any thoughts? These are 40 grain hollow points designed for TCM velocities so I'm sure will disintegrate on game at .222 velocities, but they'll be mainly for paper or if I get out west to shoot prairie dogs.

I have gotten tack driving performance out of the 45gr. HP-BEE Hornady bullet in my K-Hornet at 3,000 fps using Lil'Gun powder. I guess the twist rate is likely 1 in 16" in my 77-22 Ruger. Over cranking the little short bullets a wee bit might not affect them all that badly at a faster twist rate, although that is likely not really a very good example of actual over revving. But that little bullet was designed for the .218 Bee velocities and I have forgotten what twist rate that cartridge was given.

When I first got my Mini-14 with 1 in 7" twist rate I played around with all sorts of things, to include a 40 gr. Hornady Balistic Tip. Surprisingly, I was able to get almost the same accuracy out of that little bullet as I did with the longer 69gr. and 77gr. bullets. Likely only about a 2 1/2" group, but then my Mini-14 does good to get under 2" with anything.

I think the velocity was up around 3,600 fps. or somewhere close even in my short barrel. Not unusual for the older 1 in 12" twist barrels, but in the 1 in 7" was really cranking. I was not going to actually use that bullet so I did not keep the load, but I do remember that it was fast and the spin rate must have been unreal. I think I was using AA-2300 or actually it was called MR 230 back then I think. They changed the name.

I have decided that under revving is more critical than over revving, so I suspect you will find a decent load even in the faster than needed twist rates.
