Just updated my MK V to 338 norma. It is sitting in an A5, Near Alpha bases and rings(30 moa base with 20 moa rings for 50moa total!! Richard is all I have used for the last 3 years. His bases and rings especially are without question the best I have ever used!) 30" Schneider 9 twist with M40 contour, Tubb break and level, Nightforce 5.5-22x56. Just waiting for brass....I think after seeing this post I will opt for the mag extension!
Is that your rifle pictured? If so, what caliber are you shooting, what glass do you have on it and how much does it weigh?
Yep, that's mine. 338 Excalibur. The average case capacity in grains of water from the once fired cases with a spent primer seated in reverse is 140.1 grains. Built by a very knowledgeble/capable expert smith on here. It wore a S3 6-24x50 Sightron, but another optic is going on it. Don't hold me to it as I can't touch the rifle at the moment, but I think this came in right around 15.5 lbs with that optic. I need to post a rifle build thread on that rifle. Hopefully APS or somebody sources some economical brass for the chambering and breathes some new life into the round. This chambering made me skip the 338 Cheytac chamberings, and have 375 Cheytac Improved built instead. Certainly not claiming it's in the league of those rounds, but the accuracy load was 122 gr of H50BMG pushing a 300 SMK at 3070-3082 fps out of a 31.25 9.8 tw Brux. My goal was 3100+ with the 300 SMK. Probably could get there with a bit more load development, but didn't want to eat up the barrel chasing 25 fps.
