My old 338 WM boat paddle shoots both 210 partitions and ttsx's sub 1" for 5 rds at 100 yds. It's essentially stock minus a trigger and a bedded action and the first 2" of barrel.

My specific 338 rifle nor the 4 other boat paddles I owned have never been any more picky then anything else I have owned. Solid base rifles IMHO that I would still own if others hadn't offered significant premiums on them.
