Thanks fellas. Ill do some researching and reading and video watching.

And Yes the brass was fired from this rifle.

i dont have the headspace kit. Ill have to pick one up.

That’s most likely a case of the sizing die squishing the diameter the case causing a portion of the shoulder to squeeze up - the die is slightly long compared to your chamber so it doesn’t push the shoulder back enough for easy chambering. If the die won’t screw down further onto the shell holder the only choice is filing or grinding down the shell holder (or bottom of die), until it chambers easily. I’ve had a friend simply change brands of the die and it fixed the issue, but I’d rather grind a bit off the bottom of the die.
