I became very very interested in the little 22TCM after finding some articles on it. I've read quite a bit about the round and decided to build a mid range varmint rifle for local ground squirrels, which I truly enjoy hunting. If I like the way it shoots, I'll build another one for my grandson since I have another Model 7 receiver. The factory rifle is basically a beefed rimfire which doesn't have the rigidity I prefere. Hopefully, for those who want a more accurate firearm, some manufacturer will start building rifles on a centerfire receiver, if they're not already doing it. I'm fairly certain the cartridge will have to get a SAAMI spec before they will though. Right now it's considered a wildcat.
I'm going to build the rifle on a Remington Model 7 receiver, one of which I've had for some time. The receiver and bolt will be blue printed and I will use a heavy duty recoil lug. I'll glass bed the action and float the twenty-four inch PacNor barrel. Because I'll be shooting the 36gr Varmint Grenade bullet, the barrel twist is 14 tpi which will stabilize the little bullet quite nicely. The lead free VG bullet is required for hunting in the People's Republic of Kalifornia.
I'm waiting for the chamber reamer to arrive from Pacific Tool and Gauge. It should be here. Next week. I thought I would document the build for anyone who might be interested and publish my testing results after I begin shooting. I'll be reloading my ammo, but I will also test factory rounds so that those who don't reload have a reference. I already have three boxes of factory ammo to shoot.
Since I'm not concerned with overall cartridge length, I'll be seating the my bullets so that the bearing surface is mostly in the neck, with the base of the bullet even with the neck/shoulder junction. I'll be using Redding dies, which I already have and I'll be using them in the Redding turret press. I plan on starting with Lil Gun powder, but other powders will be tested. The round should be good for pressures up to about 55,000 psi since it's designed using the 223 case deminsions, but I'll approach that pressure carefully. Anyway, till next time. I'll get things going as soon as possible and take pictures of the build as I progress.
Everyone has a right to do stupid things. Unfortunately, politicians tend to abuse the privilege.
