I had some issues with that and another brand..
I found my issue...I had used frog lube and it was cold outside...that stuff does not get used on my guns anymore.
I did what i hate to do.. I sprayed my gun and parts clean with wd40 and blew them off with compressed air from a small compressor we had on hand..Then wiped all parts down with bounty paper towels.
No issues after that.
So maybe it was colder than normal and your lube did not care for it...Maybe not..maybe a bad batch.
Pull some bullets and weigh the powder charge.. see how consistent it is.
I done that on some recent 30-06 ammo.. not good.
That explains the 250 fps spreads.
