Talking same gun, same day, but different loads.

I'm at the range right now taking a break between groups. Testing out new elk loads for next week. I used my deer loads to confirm being on, and as fouling shots. Two shots, with in an inch. Ok, seems normal.

I go to my first new load. For time, and a finite supply of these bullets, I did 1gr under max, and one max. First test was

165gr FailSafe
1 under max imr 4064

This got me sub moa.

Next load at max. Looks to be closer to moa but still under. Things are going great!!

So I run the bore snake, and hook up my air mattress pump (thanks z man) and let that run a bit.

Fire another two fouling shots...touches.

Next load up
Same bullet
1 under max RL17

......it took a while to find the hole. Pointing at center, it hits the upper left diamond! 2nd shot back near center...3rd....halfway between.

This is the biggest shift in poa and biggest group I've ever shot with hand loads.

Anyone else seen this??
