Ammo problems

[mrgrinch1223]

I went to the range today and bought some new Superformance ammo for my 7mag and the bolt would not close, have not had any issues with Federal premium and or Win Supremes. The gun is a Sako Finnbear. Here is the odd part, i have a parker hale 7mag and the the bolt will close on the Hornady ammo. Any thoughts as to the issue?? i realize that this forum is set up for BR (which i do own a 6 BR ) just thought the knowlege here in the forum far greatly exceeded mine.

Thanks to all who looked, called Hornady this morning and it seems as though there were some issues with the brass as it pertains to certain guns approx .002, problem resolved.

That's SAAMI specs biting you on the dark side. The more aggrevating problem is with dies. Shoot a round and it will rechamber, size it and then it won't. Doesn't happen often but when it does....bummer.
