Rimfire Ammo Mistake for Match

[TIMMYTOY]

We had a match on the 19th was all set with my Vudoo I thought!
started match and was hitting low could not figure out why under pressure/time I struggled through the match!
Couldn't hardly sleep that night it was bugging the hell out of me the Vudoo shoots lights out to 300yrds"
Up early and at the range yep shooting low crono ammo slower than I had in my Kestrel what the heck? same ammo NOT different lot #
reloaded kestrel with proper mv back on track !
Ya Rookie mistake.

Was there a significant temperature difference (90's down to 60's or lower) from the previous time you chronographed the ammo to now by chance?

The rookie mistake had nothing to do with the ammo shifting zero. It happens, and it ain't just rimfire. We like to joke around that 1,000 yard zeroes are +/- at least a Minute.

The only rookie mistake you made goes a little somethin like this:

"Thou shalt not commit thyself to a sight change until at least 3 consecutive shots have gone the wrong place."

...and a second line that often accompanies rookies...

"Upon adjusting thy sighting system, thou shalt not at any time move bullet placement more than 1/4 the distance to the intended point of impact without placing another round on target to verify that you did not yet adjust far enough. "


The sights move for a reason, and you need to move them assertively and timely when the circumstances dictate that you do...even if you can't "see" why.

If the holes or splashes don't show up where you want, MOVE your ass. Don't get so wrapped up in the science of WHY the rounds aren't going where you want that you forget to PUT them where you want.

Maybe 10 degrees different.
I did adjust at 50yds but at 120 etc I was lost not much for splash due to weeds/grass.
Did get some advise from top prs shooter he said when your in that position tell the range officer your going to burn a round into the sand part of the berm then make adjustments from there.
