Most folks don't realize there's typically more spread in the flame output from the most uniform primers made than the flame output from metered powder charge weights. For decades, competitive shooters have got better accuracy from metered (thrown) charges of extruded powder than exact charge weights of ball powder.

Consider the following where powder charges are thrown direct from meters and not weighed to exact amounts. . . . . .

* Benchresters shooting up through 300 yards.

* Sierra Bullets testing their stuff for accuracy at 200 yards.

* Commercial .308 Win. match ammo that shoots 2/3 MOA at 600 yards.

* Arsenal loaded 7.62 NATO match ammo that shoots 1 MOA at 600.

All of the above will shoot no worse than 1/4 to 1/3 MOA at 100 yards in a properly built and shot rifle. If you're not shooting your rifle and ammo that well, you're wasting your time weighing powder charges. Stop weighing and just dump charges direct from your powder measure then do proper testing shooting at least 15 shots per group.
