I have 1160 rounds of 300 BO. I sold my Sig Rattler and decided not to replace it. Here is what I have: 


Subs:


-140 rounds Winchester Super Express 200 gr


- 120 rounds Sellier&Bellot 200 gr


- 250 rounds of Nautilus 220 gr


- 250 rounds of Lithium Ammo 220 gr


- 130 rounds of Magtech 200 gr


- 50 rounds of Capital 200 gr. 


Non subs:


- 150 rounds of Capital 147 gr


- 50 rounds of Rangetime 150 gr


- 20 rounds of Ammo Inc 150 gr. 


My Rattler ran through these with no issues. This is a package deal only.
