Re-33… that makes sense on the velocity.
I have no idea how you got that rig to 10.6#.Well not a Papua but it's a 338 Edge ,300 gr. bergers , 30" proof ,T-3 terminator in a McMillan Game hunter Edge , Remington stainless action , 20 moa rail , heavy 34"" rings , Burris XTR ii 5 x 25 x50 .
All in its 10.6 pounds . I have a another 338 Edge at 14.6 pound and my heavy one is 19.4 pounds . It's been out to 3027 yards so far .
I'm building another 338 Edge but 27" barrel and a lighter Scope .
Last years Elk at 1244 yards .
