i agree 6mm factory ammo is a bear to come by. I shoot 105gr remington extended range flat based shells. I am very pleased by their preformance remington quit making them like 5yr ago but theres a sports shop in my town that has a few boxes left and i just picked a extra one up tonight because i saw there were only 3 left so after the holiday season im gona go pick up the other 3 so ill be set for awhile. I also reload my 6mm but these shells shoot awesome in my gun and penetrate beyond belief so if it and broke dont fix it. I'm using my reloads for varmit hunting currently but when i run outa these shells im done with buying ammo. I'm gona roll em all. As for 80gr in 6mm im sure they will work fine but for deer size game i like to shoot atleast a 95gr but place it right and im sure u'll be eating venison. Good luck...
