There are some that will say that they are bad bullets, but I use the 150 gr. Ballistic Silvertips in my 7mm Rem mag with excellent results for white tails here in Alabama.
I too am a Gameking user, but I got these at a good price and am extremely happy with them.
The Accubonds are a pricey bullet to be sure, but my son uses them in his .308 with success.
