I bought a new Rem 700 SPS varmint in .243 that I have not shot yet. I have heard some things that I should do before I shoot it to make it the most accurate rifle it can be. I have heard shooting special bullets, lapping?, and a few other things. What would you recommend I do so I can have a production rifle that shoots great. I understand the rifle will probably shoot better than I and I can use all the practice I can get. Those are given. Just wondering how to accurize the new rifle. Thanks for the expert advice.
