Isn't the 6-30 brass different than the regularly available saum brass? If so, then I wouldn't worry about the headspace being a little short (if it is) because you're in handload only territory. The only issue is if your next round of brass chambers or not. If it doesn't, then run It through your size die until it does.
Do both.
I LOVE the 6UM, but most people don't need it. How often will you shoot past 500 yards at animals?
What "go gauge" are you using? A specific "6 UM" go gauge in 30⁰ or 40⁰ that matches your chamber?
Almost never I'm guessing. Currently, I wouldn't shoot passed 600 or so and conditions would have to be just right. I'm just liking the idea of an 18" barrel with lots of speed using the 112mb or 115dtac
I've got a 223 for targets and training and trying to limit my bolt rifles to 2
I have the go gauge from UM for my chamber. I guess my tikka is just a little off the usual tolerance.
As great as the 6 UM is...probably not. It would be a bit like driving an F1 car to work every day. The 6 UM starts to outshine the standard capacity cases at over 800 yards.
Very true. I don't think I've run the numbers until now.
Running the numbers through the WEZ makes it even clearer. There's basically no difference at that range.
You're referring to hit probability?
Yes exactly. There's not much difference, with 2-4mph wind uncertainty, until 900+ yards. Even then it's single digits.
You could just do a 6 PRC. Single neck down on 6.5 brass. No firefirming. Right in the middle between the Creed and the UM.
Touché
A braked 6PRC kicks less than an un-braked 22CM. I can tell you that much.
