Quite a few years ago I bought 2 boxes of the 300gr Barnes Originals from an outfit that was going out of business. They shot very well in my Rem 7400 (1 in 16" twist)at around 2340 fps.

Also, in my Rem 673 in 350 RM. It too had a 1 in 16" twist. Atkinson is right, H414 is an excellent powder for that bullet, as is RL-15. They are no longer produced by Barnes but I expect the 310 Woodleigh, being the same length, would be similar in performance.
