6mm tcu

[pistolman44]

Does anyone here cast a GC Boolit for a 6MM TCU. This caliber uses a .223 Remington case necked up to .243". The gun is a TC Encore pistol and the barrel is 15" heavy bull brl. I shoot 55gr to 75gr JSP boolits which are very accurate. Brl. twist is 1-10.

Check with or PM Badgeredd. IIRC he has one or two.

This may not help but I have been shooting CB's in my 7mm TCU exclusively for several years in both my Contender 10" barrel and my Contender carbine (custom 18" barrel). Both give great accuracy with the 130 gr boolits and I use my carbine for coyotes a lot.
My load is just under 20 gr of 4198 giving an MV of about 1950 fps so I am sure it it work well in your 6 mm TCU since it is a relatively light load. At that load I did a "wet phonebook" terminal ballistics test at 50 yards and got 15 inches of penetration with perfect expansion. That same load in the 10" barrel has an MV of just under 1600 fps.
