I have some information that is a little different than that from Hopalong7. I could be wrong because I don't have a complete catalog no 10. However, I have the cover of catalog 10 with sheets that have TCR options. I think they are also from catalog 10 but am not absolutely 100 percent sure. The date I had written on the catalog cover was september 1993 so the TCR's there would have been TCR-87's. Both the single trigger TCR Hunter Rifle reciever assembly and the double trigger TCR Deluxe Model were shown. If the TCR shotgun reciever assembly was in the catalog, I do not have that page.
The regular factory rifle barrel offerings were 23-inch light sporter rifle barrels in .22 Hornet, .222 Rem, .223 Rem, .22-250, .243 Win, .270 Win, 7mm/08, 7mm Rem Mag, .308 Win, .30/06, .300 Win Mag, .338 Win mag. The 25-7/8-inch medium sporter barrels were offered in .223 Rem, .22-250, .220 Swift, 7mm/08, .308 Win, .32/40, and .416 Rem (with muzzle tamer). I do not understand why the 7mm Rem Mag and .300 Win Mag were offered in the light 23-inch barrel but not the longer heavier barrel.
There was a choice of two 22-inch shotgun barrels in 3-inch 12-ga both with iron sights. One had a smooth cylinder bore and the other had a fully rifled bore. There was a choice of two 25-inch shotgun barrels. One was 12-ga with a 3.5-inch chamber and the other was 10-ga with a 3.5-inch chamber. Both had a front bead and s "full" insert choke.
The TC Custom Shop barrels were either a 20-inch (light weight) Custom Carbine Barrel, a 24-inch Sporter barrel, or a 24-inch Bull Barrel. The availible calibers listed were 17 Mach IV, 17 Rem, .22 Hornet, .22 K-Hornet, .222 Rem, 22PPC, .223 Rem, .222 Rem Mag, 220 Swift, 6mm PPC, 6mm TCU, 6.5 x 55, .264 Win Mag, .270 Win, 7mm TCU, 7mm-08, 7mm Rem Mag, 7x57, 7.62 x 39, .280 Rem, , .308 Win, 30/06, .300 Win Mag, 35 Whelen, .375 Win, 373 H&H (only in Bull Barrel with tamer), 38/55, .416 Rem Mag (only in Bull Barrel with tamer, and 45/70.
They would also make Custom barrels in calibers not listed for the TCR's. For example, They did not list the .22 CCM for the TCR but did list it for the Contender. Per a telephone call they agreed to make one for a TCR in that caliber. I think I also called about a bull barrel for the .264 Win Magnum and they said they could make on in a 26-inch length.
