If it doesn't shoot great right out of the box keep putting a few more rounds down range. I have had a couple of Savage rifles that didn't start shooting good till I had 50 to 100 rounds fired and a couple of cleaning sessions. I use JB bore paste to clean "rough" factory barrels.

Sierra 52 gr HPBT 1410 Match gives me the best accuracy in mine, typically under 1/2 MOA, sometimes much better. This bullet is also an excellent choice for small varmints (prairie dogs) even though it is billed as a match bullet.
