The good advice I have gotten here has been paying off in spades. I shot a 0.180 yesterday (3 shots, 100 yards), the best I have ever done.
The 308 I built and barreled was shooting around the low 3's with 150g bullets seated for a mag. I started working with 180g bullets about a month ago, trying various powders and yesterday with 180 SMK's seated just touching the lands, with 43.3g of IMR-4895 (slightly sticky bolt lift at 82 degrees F.), I shot this great group.
I was shooting 3 shot groups because I was still doing load development -- I realize that I need to duplicate this with a bunch of 5 shot groups before I have legitimate bragging rights, but the notions of bigger bullets, seating into the lands, consistent neck tension, etc., really does make a difference.
