I only shoot the ballistic silvertips through my X-Bolt. I know what can happen if you don't sight your gun in with the ammunition you hunt with.
Thankfully I learned that lesson in the summer. My father had me switch ammo types because we couldn't buy the round we had been using for his .44 mag rifle. Going from a cheaper 220 grain hollow point to a higher quality 240 grain hollow point round really shifted the zero and tightened up my shot groups. It left a big, and lasting, impression on me.
Oh, and I second the buy at least one spare magazine advice. I never lost a magazine while in the woods, but my father has.
It has happened to me only once where I had a defective aftermarket magazine out of the box, but my father's A-bolt mag had a spring that broke during one gun deer season. He had a single shot rifle for the opening weekend that year because he had no spare magazine.
Be prepared, and you increase your odds of success.
