I just ordered a barrel from True Sporting Arms. It is a 6x6.8 1x9 twist 16" that says it's throated for 58 gr Vmax. For $86 and free shipping I couldn't pass it up. Will I be able to load anything other than the 58 gr Vmax or is it a one trick pony? Also, will standard 6.8 SPC go/no-go gauges work?

Is this an ar15 barrel? The go/no go gauges should be for the apparent case. But if it’s an ar15 how do you adjust head space isn’t that set by the barrel manufacturer? Proably a question for Greg or Ritch. You should be able to shoot other bullets in it hopefully this barrel isn’t one of the ones with the short throat issue or whatever has been going on. But you got it cheap enough if it shoots it works. Look to 8208 for powder.

Will I be able to load anything other than the 58 gr Vmax or is it a one trick pony? Also, will standard 6.8 SPC go/no-go gauges work? First off that statement is really not accurate and is poorly worded. The chamber was designed to shoot the 58's extremely well as it was envisioned as a coyote round. It will shoot anything else you want up to about 95's. Ritch's son killed an antelope at 646 yards with a magazine feed 90 Berger. I routinely shoot 87;'s in F-class at 500 yards. The use of Go/No Go in an AR is worthless other than as a quick check in an AR. The 6X6.8 is a wildcat and is non-SAAMI. You could use a 6.8 gauge but since you can't change what you have it matters not. Also it is always best to use a set of gauges made by the people that made the reamer. You will be forming the cases out to your chamber and adjust your dies to that. For further clarification we may move shoulders up and back in both the 6.8 and LBC chambers. Most times a standard HS gauge could be used but the extra variation of 0.002-0.003 may well cause you consternation. The wildcats are changed in many measurements and as the cases evolves these changes may be subtle and not noticed unless you have a reamer print in front of you and reamer prints are not distributed for obvious reasons.

I was just going by what was printed on the page for the barrel, "Throating is set for a 58 grain VMax bullet." I thought it would be fine for other bullets I just wanted to make sure. Thank you for saving me money on the gauges. Everything I've read says you need to check headspace before you fire the rifle. If I don't need them that's money to spend on reloading components. I'm looking at the 87gr VMax as a good all around coyote/prairie dog/target bullet. Any other bullets fit that role better? Thanks for your patience with my ignorance on the subject.

58 VMAX or 70 SPEER TNT are the good coyote choice many like. I'LL post a pic later.

Here you go. 417 yards with a 6X6.8 and 58 VMAX shot by the cartridge designer last weekend. Greg
