I know volume sorting is better than just weight sorting, but whats the best way to do it? Is it better to do it with water or just a really fine powder like H414? or is weight sorting the way to go?
Thanks
Thanks
I have got 0.069 moa with the load I have now at 100 yards, and have shot a 2.685" or 0.641 moa group at a 1,000 yards with a similar load I often use. I'm willing to do the extra work of volume sorting. It also helps i'm using Norma brass. I've done almost everything else I can to squeeze every ounce of accuracy out of my system. Volume or weight sorting is about the only thing I dont do.Sort rifle brass to a 1% spread in weight. It's not worth the time, mess and insignificant results to use some method to measure case volume. You have to first fire form the case first to get its dimensions more uniform than virgin brass has. It ain't worth the expense and barrel life for me to do that. Until you're shooting at worst, 1/4 MOA at 100 yards, 1/3 MOA at 300, 1/2 MOA at 600 and 3/4 MOA at 1000, don't waste your time; just weigh cases. Accuracy that good happens routinely by weight sorting and neck turning if neck walls have more than a 1/1000th spread in thickness with good dies and techniques. No other case prep's needed.
Are these stated groups the largest you've produced?I have got 0.069 moa with the load I have now at 100 yards, and have shot a 2.685" or 0.641 moa group at a 1,000 yards with a similar load I often use.
You're right on the 1,000 moa. I had my OnTarget set to 400 yards when I referenced it. The 1,000 group was definitely a "screamer" group. It would be nearly impossible for me to reproduce, but it has done it once with perfect conditions. My 100 yards group is usually the norm on good days but can go up to 0.155" depending on the day. Both were three shot groups.Are these stated groups the largest you've produced?
How many shots per group?
I think a 2.685 inch group at 1000 is .2685 MOA. I also think a .641 MOA group at 1000 yards is 6.41 inches extreme spread.
That's good. But you might want to decide what "accurate rifle" means for you, too. For example, what's the largest group any load has shot?The point i'm trying to make is that I want to leave no stone unturned in producing as accurate as possible loads for an accurate rifle.

Grouping undefined from center is a matter of 'precision', and not 'accuracy'.which of the below sets of five 3-shot groups at 1000 yards is the most accurate:
Group set A, ranges from 1 inch to 6 inches.
Group set B, ranges from 2 inch to 5 inches.
You got that right, as the error at 1kyd would be .47" per IPHY dialed erroneously with a true MOA scope.If the group measures 6.41" at 1000 yards it is actually 6.12 MOA. Less than a half inch difference at 1000 yards, but since the post is carrying measurements to more than two decimal points, thought it should be mentioned. This conversion becomes more relevant if you are using a MOA scope and considering inches when adjusting for long range shooting.

Do you mean calculating the mean radius from a calculated group center of all fired shots?Accuracy is not a shooting marathon, but is defined with a single shots, w/resp to center of mark.
