I generally reload my ammo but I buy Remington factory shells to test new guns with and have had excellent performance out of it. In my 6MM Remington the 100 grain bullet shoots 3 shots into 1/2 inch and my reloads can only match this not beat it. I killed a huge muley at 300 yards with a hit in the neck with the 150 grain PSPCL out of my 30-06 when the Airline refused to let me ship my reloads because they were not in the "original factory box", the plastic containers not being legal. I have had good results with all factory ammo I have tried except Hanson.
