i use the cheap green box of remingtons and have never had one that underperformed. The first deer i ever shot was with a brenneke, and when your throwing a full ounce of lead downrange the type of slug doesnt really make a difference. I can cloverleafe the Remingtons at 60 and have a 3 inch group at 100. Thats good for any deer, and if you do your part any slug will do more than its part in penetration and destruction of vitals.
Beware the man with one rifle... He probobly knows how to use it.
