Re: lightweight 338 edge
I shoot a standard .338 RUM in the XCR. Not fancy, but with a young family a custom is out of the question. It's lite, not sure how lite, but I would be suprised if it were over 8.5 (without bi-pod). I havent met many people other than my Dad and myself that can shoot it well, so recoil is stout.
I have shot under 1\2" groups with it, but the norm is around 5/8"-3/4".
I have pushed the 300 SMK at 2850 fps with a 26" tube, but I wasnt the wisest handloader at the time. I now shoot the 300 bergers at 2765 fps. I have shot the 210 TTSX at 3400 and the 225 SST at 3300"ish" (chrony was being a bugger, so I went off my drops). The lighter bullets are very easy to shoot in comparisonm to the 300's.
