I can't seem to find data on loading the 6.5 creedmoor with 140 gr Berger VLDS or the new Barnes 127 gr LRX. I have H4350 and RL19 and 17. Currently looking for information for these bullet/powder combos only. Can someone give me some min-max data on these or point me in the right direction?
Thnaks in advance.
I'm using 27.8 gr of H4350 with Fed match primers and my Cooper shoots in the .2's all day, I am using 142 gr Sierra match and getting 2766 fps at 2800 ft elevation. 27 moa up to be dead on at 1000 yds. Shot a 2.5 inch group at 500 yds three wks ago with the same load.
With a 28" Criterion Bull barrel I'm shooting 140 gr Berger Hybrids at 42.6 gr of H4350 with a Fed 210M primer (which is over the published max of 40.7, starting load is 36.5 in the Berger manual). I got this load from another creedmoor shooter and have read of others using this load also.
I definitely would recommend starting below published max and working up slowly. I finally hit visible pressure signs at 42.9, your barrel will undoubtedly be different.
I have read and been told that a CCI BR primer is the best primer going for H4350. I have no idea if there is any merit to that but thought that I would drop the charge weight and work back up to try it out.
I don't remember length to ogive but I think its 2.200. I know for fact that it will just barely fit in a Accuracy International 308 magazine. It also will shoot 5 in the .2's. At 5450' elevation, it is 11.0 mils to a medium pumpkin size rock at 1315 yds. My chrono shows 2859 average.
I've found that there is more and more lot lot lot variability lately with H4350. I've been using it exclusively in my creedmoor shooting various 139-140 gr pills with great success in my match rifle. Charge weights have been from 41.5 - 42.5 depending on lot, I'm currently using an 8#'er that I can stuff 43.0 gr in and not show pressure, go figure! Velocities range frm 2750-2830 fps typically.
I'm planning on shooting that Barnex 127LRX on a deer hunt in a coule weeks, I'm pushing it with 41.5 gr to about 2,740 fps.....I'm sure I could go faster but it's stacking them into a ragged hole.
I have a load for the 140 Berger using 41.8gr of RL17, CCI BR2 primers, seated .02 off the lands.
I'm shooting sub 3/4" at 200 meters, chrono is 2856 avg.
With the 127 LRX, I have a load with 46.5gr gr Super Performance, .07 off the lands, shoots .3 at 100yds at 3037 fps.
