I have had smaller #3 contour barrels shoot 1/2 MOA, but like CTK stated, it took a lot of load development to get there and there are generally only one or two recipes that will yield that level of accuracy. Since I started using heavier barrels, load development is much easier. I am in the early stages of development with the RL26 powder in my 6.5 Rem Mag and have already achieved zero vertical and sub 1/4 MOA groups at 100 yards. I believe with some seating adjustments, I may even be able to tune the groups into .1's. I will have to see...
My 6.5 Rem Mag wears a #6 contour barrel at 26" long. There are about 4 different powders with various charge weights Ive tried that it will shoot 1/2 MOA or less groups with. Probably 1/2 a dozen load recipes in total yielding sub 1/2 MOA accuracy. Nothing I have ever tried in load development has shot 'unacceptable' groups at 100 yards for a hunting level of accuracy. I believe the worst accuracy I have ever seen from the rifle from all the different powders and charge weights tested is about 1" at 100 yards. My other heavy barreled hunting rifles have similar traits of forgiveness. I like what I am seeing with RL26 the best because the powder gives good speeds, no vertical, has good temp stability, is obviously accurate, and is the only powder I have tried in the rifle that does not throw a clean/cold bore flier. Not saying that RL26 is the best powder for every application in hunting, but my particular rifle seems to favor it very well. Of course the real results will be determined when I get it on paper at longer ranges of 300, 600, and 1000 yards.
