Interesting poa/poi shifts. That’s a similar direction when I test light for caliber rounds. Looks like they moved from star line brass to their own version of brass. I wonder if they are making it themselves or having it made for them.
TRIGGERBAR!! First comment I’ve seen in weeks from you! haha
I'm not all that certain those shifts aren't just me.
It's why I shot the 2 Liberty groups the way I did and sure enough they don't match up that well. The one is 1" higher than the other and .5" hz shift, too!
Of course it could be the ammo...but at this point...it's "close enough" for me. The Magtech group is also .5" further right than the last outing and I didn't adjust the dot horizontally.
I'm a little agitated with myself because I shot a couple of boxes of the Underwood and didn't realize those also had different LOT#s. I didn't chrono it because I was only checking cycling after the new mag-springs. dangit! And I was standing so I could be sure to lessen the chance of limp-wristing it like I do when I am trying to check POI & groups and hardly even gripping it.
Oh well. You'd think I should know by now to pay attention to the boxes better? jeez
and yeah, to your point about the brass - I wonder now if they lightened the charge on purpose because of the brass? And maybe not as strong?
It's exhausting trying to guess what these companies are doing when they change their recipes!!
I only bought the 1st box to see their velocity from my 4" barrel so I could gauge my own loads better. I wasn't planning to carry theirs, but was happy enough seeing it right around 1200 fps that I bought 3 more - none them I see now match that LOT#. duh!!
@@ShastaBean lol. yah it’s super frustrating that every time we buy a box of ammo we have to test it. I’d say for the most part you are right that the shifts are small enough to not make a difference. The underwood has been disappointing me lately. I got some Rowland rounds that were 200 fps below box. Very sad.
@@triggerbarPhD that's sad. Was it brass stamped with "Underwood"? Or something else like the *---------* ?
