Gap-10 .308 178 amax oal?

[EasternNChunter]

I am still several months out from getting my GAP-10 .308 but have stocked up on components and pmags. I plan on using 178 AMAXs with Reloader 15, Lapua brass and Large Rifle Magnum primers as I have several thousand and my buddy uses them in his AR10. What OAL are you guys loading the 178 AMAXs to in your GAP-10's? Mag length?

43 grains of RL15 in lapua brass is a safe bet. I didn't have good luck with 178 amax in my DPMS SASS until I seated them deep. 2.78".

Every rifle IMO is different. I've seen a lot of guys seating at 2.81" with good results, but I found mine did best at 2.79". I would load up a couple groups at 2.81-2.79 and see what performs best.
