[QUOTE="trueblue, post: 442573, member: 10654"] biggreen's post is right on. I would add that the first thing I would do is find your top end of pressure for your powder charge, then back off and work on your load developement. Need to use a chrony if you have one. 175gr SMK seems to be a popular bullet for the 308 for target., and out to 1000yards. If you are not going to shoot that far, the 168's will take you to about 800yards. I would look at shooting Nosler AB for hunting , or maybe even Barnes. Since this is a factory barrel, I would not spend forever on barrel breakin, just shoot it and clean it and you will be fine. It wil break in on its own with some rounds down range. I would not bother with 100 rounds to do barrel breakin. If you are going to shoot this rifle past 500yards, there might be some benefit to cleaning up the necks, or spend alittle more and buy Lapua brass for the 308. As far as powder, I strickly use Hodgdon extreme powders as I don't want velocity changes due to temperature changes. I use Forester dies. I would recommend a bushing die so you can partially resize the neck when reloading, leaving a small part by the neck/shoulder area unsized. This will help center your loaded round in the chamber. There are better ways to measure your chamber length and ogive measurements than using cerrosafe on the chamber. [/QUOTE]
