Testing the new V-3
CYA friends:
I'm using the action from the spearment that I sent to the Barn, that Robert Oates kicked out that amazing 29 total round, 17X PSL card with.
This action is one of the original 10-X actions, which were longer in the tang and front receiver ring than all other TCA actions, including, of course, the new V-3.
Anthony DiOrio, hopefully, plans on giving us a XP length V-3 for pistol use, one day.

Anyway, the killer 4 groove Muller, that was on my spearment, was just sitting on my work bench doing nothing.
So yesterday I decided to re-fit it to my V-3.
The barrel would not physically screw into the V-3.....which is common between the Turbo and 10-X actions.....even though they are both 16 pitch and have .750" OD tenons.
So I set the barrel up and deepened the threads.
CYA friends, when I deepen threads I only remove material from the non-bearing side of the threads.
I do not touch the bearing sides of the threads.
This way the threading remains identical, when deepened, to the way it was originally...
I wouldn't do anything to this killer Muller to alter it from the way Robert Oates shot it at the Barn.
And then I had to move the barrel shoulder about .008", to gain my .044" HS, that I wanted with this new V-3.
By the way, the HS was also set at .044" on my spearment, when Robert shot it at the Barn.
CYA friends, since I've machined breech and muzzle targets on every barrel I ever done, allows me to do this thread deepening and to move the barrel shoulder, and keep them perfectly true to their original configuration.
So now I've got this killer Muller fit to my V-3 in the exact same configuration as it was on my spearment.
Nothing has changed, except the action that this fine Muller is on.

I'm headed to the range.
It's 60 degrees, but it's supposed to get very windy later, then turn down into the 30's tonight.
So I have to test now...
This is citing.
The new V-3 allowed my old Lilja slave to produce the same accuracy as I got with my prototype triple back on March 26th of 2014.
I'm cited to see how this new V-3 does with this killer Muller.

PS:
I thought about carefully turning this killer Muller down form .900" to about .815", and using it on my new triple pistol..
But, that would have required some additional lapping......so I decided not to chance it.
One other thing:
It was cool in the shop yesterday.....high 50's, and I did not turn on the heat.
So when I test fired this Muller on my V-3, the first thing I couldn't wait to do, was to check the firing pin footprint depth.
Sometimes I still think I've been dreaming about the way this V-3 will drive a .033" width footprint, with only 8 pounds of firing pin spring pre-load......
No, it's not a dream.....even with the temp in the 50's, it drives exactly the same.......
And the bolt lift is like a very free, 90 degree action.......amazing.
WHY?
