If you are getting consistent sub-MOA groups out of that rifle and load combination, you may want to consider stocking up on some of that particular lot number of that ammo. Hand loading is both a rewarding pastime, and can also be a frustrating one. You may have a tough time duplicating the performance of that factory load in your particular gun, but go ahead, get started, and get your feet wet.......be safe, and good luck!!.....
