Just recently put together a AI stocked Remington 700 S/A action 26" barreled .308 1/8, glass Leupold mark 4 4-16x50 (12lb). I broke the barrel in using a David Tubb's final finish system shot 50 bullets. I'm currently shooting Speer 165gr BTSP, 41.6gr H335. I'm shooting out to 500m at this time...
