We started holding 600 informal matches after are regular 1,000 yard match . It gives shooter another chance to test their rifles and win a little prize money. I have been using one of my 6mm Dasher for this. We are shooting one target and its a 10 shot group not 5 like regular 600 club matches. The question is will a accuracy load that will shoot under 4 inches at 1,000 yards under good conditions shoot smaller groups at 600 yards well with the same load surprisingly so far the answer is no!
In the two matches I shot I had a 3.6 inch 10 shot group and a 4.1 10 shot group conditions were not terrible but this same load will shoot that good at 1,000 yards so what gives. In two matches nobody shot under 3 inches and that's with some of the most accurate rifles on the planet . Firing the 10 shots instead of only 5 really does increase the hardness factor but I would think a 2 inch group is doable.
The next test we are going to do is slow the Dasher down a little bit to see if that tightens things up because the straight 6mmbr is a proven winner at 300 to 600 yards so were going to get down into the 6mmbr speed zone and see what happens. |

Does slowing the dasher down create any unexpected issues like load density?

Load density is not a problem when using H4895 Varget or RL15 they all come up to the shoulder junction even with fairly light loads. There are always 3 different accuracy nodes since we shoot 1,000 yard competition just about everyone tries for the highest node they can hit which is 2980fps to 3040fps. For 600 yards I want to see if I can get the lowest node to group better than the high node I currently use. I hope to do some testing this week to see what improvements I can make by going slower.

Got to do some testing this morning conditions were pretty good. Slowing down the Dasher seemed to help. the loads I tested were all in the low 2900fps range. I tested the 105gr Berger VLD and the 107gr SMK the first load I tested was the clear winner giving me a nice 1.6 inch 5 shot group the second best was also the 107gr SMK with .2 grs more the Bergers were disappointing which surprised me because I have always had good results with that bullet. Since the load with the least amount of powder showed the best results I will work around that load. Also I have a real assortment of brass so I will need to get everything up to benchrest quality from here on out.
