Re: GAP-10 Match Rifle Idea!!!! 6mm Creedmoor
<div class="ubbcode-block"><div class="ubbcode-header">Originally Posted By: Steelhead</div><div class="ubbcode-body">Ok, I got to sneak away to the range for a bit this morning.
My load with the Hornady 105 BTHP's is 41.2gr. of H4350 at an OAL of 2.74", so I gave the same load to the Berger 105 Hybrid's, however, I loaded them long (7.795"), because in the past I've found with other Berger bullets I've had to load a bit longer to get the best accuracy. This didn't work so well this time. I had a couple of instances where the tip of the Berger bullet hit the chamber opening and was damaged, thus throwing accuracy off.
That being said, I got to test the load at 110 yards, 700 yards, 785 yards, 900 yards, and 1040 yards.
Groups at 110 yards seemed to be on par with the Hornady's. I've gotten 1/2 moa groups, and the Berger's looked like they will do the same. The group was under 1 MOA, but was opened up a bit more than the Hornady's, I believe due to the bullet tips getting damaged, as explained above.
At 1040 yards, I noticed that the Bergers gave me .5 MIL less elevation than the Hornady's did. I wasn't going for group size, especially since the wind picked up by this time, however groups with both Hornady and Berger were about the same on the steel plate. All were well within 5" at that range.
I'm going to load up some more of the Berger's and this time seat the bullets down further, to see if I can get away from the tip damage issues. I'm not sure when I'll have time to get back out to the range, but I'll report back when I do.
At this point, if I were to chose, the .5 MIL less elevation at 1040 yards was nice, but I don't know if it's worth the extra $10 a box. Further testing will need to be done. Too bad for me!

Thanks for the update Steelhead, keep us posted. That .5 mil is nice and would be great if seating them w/out damage tightens them up.
