H-335 or Ram Shot Tac Powder
With 70 to 75 gr. bullets in the 6 TCU be sure to give H-335 or RS Tac powder a try. Load data for one powder will work grain for grain for the other. I think Tac burns cleaner with better ES numbers.

What the heck
Quote:
One thing about those 55 BT's the BC is a little higher and I can send them a little faster. The 80 gn HP Core-Lokts have a BC of only about .255 and I quit at a velocity of about 3050 when working up the loads. I probably can get close to 3400 fps out of the 55 gns, if all else holds true to form. The BC of that bullet is .273 or so. That makes it pretty respectable for reaching out there for coyotes.

Yet to try TAC
I haven't tried the TAC powder for anything yet. I could give that a try. I may need someone to run LOAD F.A.D. or Quickload or something though.

Check Hogdons reloading data center. Select pistol cartridges and 6 MM TCU, They have data for bullets from 70 gr to 100 gr. When trying 100 gr in my Contender pistol I had to use semi pointed as the boattails wouldn't stabilize.

I have two 6mm TCU Contender Pistol barrels as well as 20" rifle barrel. I've always been impressed with the accuracy this cartridge delivers.
My only word of warning is that the Speer 6mm TCU data using H335 with 70-75 grain bullets is way too hot in my barrels. They list a charge of 31.0 grains of H335, and I'd have a stretched frame if I tried shooting that load in any of my barrels. Even a charge of 29.0 grains results is some sticky operation. Out in a hot sun during a hunt, things could get much worse. John |

6 TCU 60 deg
My 6 TCU is a Rem 722 with a Douglas Varmint weight barrel, .890 at the muzzle. The stock is original with some grain figure and a hand rubbed tru-oil finish. The rifle weighs 10.1 lb with a Leupold 12x tall turret scope. Factory trigger down to a crisp 36 oz.
On the heavy side for a carry gun but it's a Varmint rifle. For a carry rifle I like my Rem ADL 22-250 and my Savage 110 in .243. The rifle came with 650 fire-formed brass, what an exercise. The previous owner kept good records. He favored Sierra 60-85 grn bullets along with Berger, Nosler, and Speer bullets. For powders, he tried allot of loads. Most loads were with H335, 4895, 4198, Re 7 powders. I will work with 748 and 4895 powders using WSR primers. For bullets I will try some of the 66 grn fb bullets I make along with the Sierras I have. The 6 TCU is a Ugalde design.

335 amd 70 gr TNT
My notes show 30.5 grs of 335 for 3236 Fps in a bolt gun and I called it max after the first shot. 29.5 and 70GR B-tips worked real well..
