VMax = varmint bullet.....not a target bullet.

They are designed to come apart, therefore, thin jackets.

3-3.5" groups at 250 is just a little over MOA...which is not bad.

Are you shooting on a bench with a rest??? ...and I mean a SOLID rest front and back????

And....if you play with the seating depth of VMax's, it can help quite a bit.
