just wondering if .5 MOA is the best I can expect from this rifle [Stickman]
Going back to the OP's question, the honest answer is 'Maybe yes, maybe not'. It IS a factory rile after all and there are no guarantees of anything under half-MOA, or even always obtaining that. Some of these rifles hold long-range 'Factory Sporter' class bench rest records, others struggle to produce 100yd groups under three-quarters of an inch, or even an inch. It depends on 'barrel quality', and with large numbers being made to a budget, the best are really good, most fall in the middle, and more than a few 'dogs' escape into the wild.
As a 'newbie' to long-range shooting you're doing well if you've lucked straight onto a genuine half-MOA job. If you're inexperienced, you'll gain more points now from improving your shooting and wind-reading skills than spending lots of time at a bench working up handloads. Moreover, as Bill points out, the 6.5-284 is a barrel burner, 800-1,200 rounds depending on loads and the nature of the shooting, so a barrel such as yours that shoots very well is best restricted to competition and serious long-range practice. Get hold of some of the better books on precision handloading, and look for tips here on the forum - depending on what you're doing now, there may be opportunities to make your ammunition a little more consistent.
You don't say what your discipline is, but assuming it is F Class there are some good books on how to read the wind, The
Wind Book for Rifle Shooters by Linda K Miller, and
Prone and Long Range Rifle Shooting by Nancy Tompkins are excellent and available at reasonable prices on Amazon. The latter covers all aspects of competitive shooting but has a long chapter on reading the wind, and while it's mainly aimed at Fullbore and Palma sling shooters, the contents also apply to F Class.
Good shooting!
