2003年3月17日 · My favorite load for the 6mm TCU is: Remington case, Rem. 7 1/2 primer, 70 gr Nosler Ballistic Tip. About 25.2 gr of IMR 4198, the velocity will vary a little from lot to lot of powder. I shoot the new lot of powder over the chronograph and adjust the charge a few tenths, untill the average velocity is 2850 fps.

2004年9月15日 · TCU calibers..... The TCU calibers are some of the best available for the Contender. I like them so much I re-barreled a couple of XP-100's. One is 6mm TCU the other is 6.5 TCU. I use the 6.5 to whack bigbore silhouettes. I use the 6.0 to whack coyotes. Both of these are very accurate. Easy to load for once you fireform your cases.

2008年8月12日 · I went with the standard 6x45mm because it's just a load and shoot where the TCU needs fireforming to befor you have brass ready to load. Just looking at some load data for the standard 6x45mm Sierra has 70gr running at 3100fps out of a 24" barrel and Steve Timms article in Wolfe's "Wildcat Cartridges", a reprint fromm Handloader Mag. shows ...

2005年2月18日 · 6mm-223 is simply the 223 necked up to 6mm with the basically the same shoulder angle, where the TCU is more of an AI cartridge, I believe the TCU is somewhere around 40-45degree shoulder where the 6mm-223 is at 30 degrees or what the parent 223 case is. Some say the TCU can produce faster velocities that the 6mm-223, but I have yet to see it.

2024年6月14日 · Using sized cases I installed an extra lock ring on 6 mm ARC sizing die. Lubed the neck with dry graphite and it proved really easy only split one case. Out of maybe 125 cases. Using starting loads to fire form the cases to 6mm TCU specs. Even with these mild starting loads. The 6 mm TCU is showing me it's reputation is well deserved.

2018年2月16日 · Not exactly the 6mm TCU, the 6X45. This is the .223 Remington necked up with the the factory shoulder and neck length. The firearm is a custom XP-100 with the action trued, laminated stock, and a lightweight barrel to stay in the Long Range Handgun Weight limit. The barrel is a 1 in 9" twist taken off a custom Model 70.

2020年1月20日 · The 6mm TCU is a fine round in a 14" barrel. Not sure about the twist rate in a T/C barrel but I have a 1-12 twist MGM barrel that is my best shooter of a the barrels I have. It shoots the 65 grain V-maxs at 1/2" 100yards all day long. With dies available and brass that's cheap it would be a nice barrel to add to a collection if you reload.

2005年1月23日 · 6mm tcu Bill Down here in Aus I use a 6mm tcu built on a Mohawk with a 21 inch tube for shoot Wallaby and I have also taken 2 fallow deer with it. By the look of the photo's a fallow would be half as big again as a whitetail and the 6mm handled them easily. I use locally made bullits now but one of the deer was taken with a win 80gr bullet.

2004年5月11日 · 6mm TCU 80 SP = 2600 FPS.243 WCF 80 SP = 3000 FPS 6mm TCU 100 SP = 2300 FPS.243 WCF 100 SP = 2600 FPS The recoil and report with the 6TCU is substantially less than the .243, and this matters to many folks. Regardless, the 6TCU with 80-grain handgun bullets is adequate on small deer-sized game at moderate ranges.
