I’m debating building another 280AI due to the two before (mine and my brothers) had problems after shooting would develop a donut in side the case. I loved the round but hated dealing with it. Anyone know the cause?

No need for it and no rifle to put it on.

I can send the other pictures. I don’t know how to make upload image smaller to post on here.
I have a 1-7 twist 18" barrel shooting 55 grain vmax bullets. 26.5grains of Varget and only getting 2800 - 2850 fps.
What are some better powder choices? Or bullet? Built it for coyotes.
I have never noticed it till this year with my 7mag. I zero it at about 4800 feet and shot groups at about 6800 feet and the groups were about 1.5” lower. The way I am thinking is lighter air at higher altitudes it would shoot higher. Some one explain this please.
