The land owners are both LR comp shooters and hunters. Unfortunately I haven't even had a chance at them.I'd love a chance at shooting some of those pigs if you ever need another partner. You're right, Im in Livermore. I just drove up Mines road last Thursday.
I have AR10s in both calibers. Both easily shoot sub MOA. I have had 308s for probably 20 years while the 6.5 was new to me last year. The 6.5 CM shoots a bit softer and flatter. It is extremely accurate. The 308 has a much larger range of bullets and powders to choose from. I have taken deer at 450 with the 308 using handloads out of a 16" barrel. And made head shots on a USPSA shaped steel target at 500. I have shot a LaRue OBR at 1000 with easy hits on target. I have yet to have the opportunity to wring out the 6.5 beyond 300 yds but I am sure it will perform very nicely at 1000 as well.I’ve got an upper and a lower for an AR 10 build. Trying to make a decision on which direction to go, 6.5 Creedmor or .308. Looking for some help from someone that has experience with AR10s that could nudge me one way or the other with their experiences. I want to use it for long range applications. This will be my first build so any advice would be much appreciated!
