striker.......I've shot their 243 75 gr v max ammo and it performed well,,no failures and no stuck cases. Groups weren't as good as some other factory stuff in my Ultra bull.
As far as the 223 ammo,,I found a better deal at SportsmansGuide on the Ultramax 50 gr TNT. Same bullet as Cabelas offers,,,about $15 less for the same 250 quantity. Check it out.
I like the Ultramax ammo,,groups well out of my 223 bull barrel. No failures as yet with Ultramax either.
Hope that helps you out.
