Well I do have this info:

Sept. '77, JRS did the intro for Shooting Times.

> 24" barrell < Rem 700 BDL

Rem Factory 220, AVG. 2845 fps

He worked up slowly to

* 78 1/2 grs IMR4831, = 2940 AVG.

2 FIVE shot groups, 1 1/4" and 1 3/8"

The 200 NP was not on the market at the time.

I use IMR 4831 and the 200 NP for @ 3100 fps. I've shot this load more than any other. I have good case life and accuracy 1" - 1 1/2"


Maybe that'll help.
