Since my last posting in 2009 I have used RL-17 in more cartridges:

A 22" 338 RCM sporter. 61 gr of RL-17 with 225 gr Accubond for 2750 fps

Has taken three cow elk.

A 30" LA, long throated 338 RCM with 300 gr berger OTM 55 gr for 2525 fps Very low ES values

a friend's 22" 300 WSM with 230 gr bergers to fit a mag box of 2.8" 61 gr for velocity of 2735

I witnessed it slam a cow elk at 300 yds
