All right I need some help. I have a 6mm creedmoore bartlein barrel defiant action. Super tight group shooting gun. It has about 400 round down the pipe. I have a garmin chrono now so I see all my velocity all the time. It's doing something weird cold bore out to around 10 rounds or so it's stable around 3110 fps very low extreme spread. Then it jumps to 3230 from maybe 3 or 4 shots then it's come back down to 3110 node then jumps back up 100 fps then back down again and it's super random. Barrel is not hot and no pressure signs at all.
I'm reloading with hornady 108 eld and 41 grain of h4350. Loaded to Sami spec cole
The rifle is a tack driver and 100 yards even when velocity jumps. So no point of impact shift. Super super problem us at distance at 1600 yards the bullets arw going all over the place because of 100 fps jumps up and down
