Can't show the data, a newbie might be so stupid as to drop that high pressure rd in the chamber without any load work up.
And be dead...
True, but if you're that stupid, time to cull the herd.
I know you probably felt like a badass when you typed this, but it's not the burn you think it is.
Hopefully it'll make it clear to less experienced folks looking for load data that your intent isn't to help or to educate, you're just here to brag and stroke your own ego.
And so your Dasher identifies as a 6mm Creedmoor...good for you, I guess. If I want to throw a 108 at 3100 fps I just shoot my Creedmoor instead of the Dasher.
Anyways, I plugged your 3100 fps 108 ELD load (same powder, charge wt, OAL, 26" barrel, with estimates from my components for the data points you didn't provide like case length, case capacity, or projectile length) into GRT. And after truing it to the chrono data in your picture it came back with this:
That's an estimated 76,199 psi.
17% over the 65,000 psi max you keep quoting for the Dasher (already above the 58,000 - 62,000 psi that many books use), and a little more than 6000 psi (or 9%) more than the 70k that you keep insisting Alpha brass is "rated for." I sent Alpha an email asking if they actually recommend doing what you say they do. I'm interested to see what they say.
Granted it's just an estimate made by software and not actual measured chamber pressure (and you may have a slightly different case capacity, case length or bullet length) but it's not like you're measuring chamber pressure either. At best you're doing the same - using QL or GRT to make an estimate - and then hoping the actual pressure is within the safe limits of your system.
Maybe you don't shoot in bad weather, maybe you do, but have you water tested this load? If not, what do you suppose would happen if you got a little bit of water on your ammo?
If we're talking about PRS we shoot in the rain, and our gear can sometimes get wet no matter how hard we work to keep things dry. A slight film of moisture on a case can quickly turn what may be only a warm load when dry into one that's popping primers. I've seen it happen more than once to inexperienced guys chasing the upper end of velocity. They can end up with locked up actions and gas cutting on the bolt face of their rifle.
Franky, it's almost like you're just stuffing as much powder in the case as will fit (see the 109% load ratio on that 2000-MR load), crunching a bullet down on top of it, and trusting your Alpha brass to hold together while you get some wicked hot chrono numbers to post on the hide.
Which is fine I guess...you do you, boo.
But that doesn't make it a wise choice for a shooter wanting to load the Dasher in the context of shooting PRS matches.
