    I wanted to try out the lead free ammo from hornady. This ammo is very accurate out of my custom 7x57 mauser rifle. I am getting 3/4 inch groups from this ammo.I use this ammo for whitetail hunting and I am going to use it for an elk hunt when I decide to go on one. Thanks SG for having very good prices on ammo.

Rifling Twist Rates & Bullets

We all understand that a rifle barrel has spiral grooves (rifling) in order to impart spin to bullets. This stabilizes them so they fly true, like a well-thrown football. But what's all this talk about twist rates like 10-inch or 1-in 14? What's that all about and how important is it?
