[QUOTE="PapaSmurff, post: 2783799, member: 118512"] It is an extremely efficient cartridge indeed. I just worked up a new load for mine today. It is a Ruger 77 Hawkeye that was originally chambered for the 338 RCM from the factory but I didn't like the thin barrel so I had my gunsmith re-barrel it with a #4 Bartlein 22" (should've went with a 3B contour either 22" or 24" if I was to do it again) and man does it shoot for a traditional style hunting rifle like most of us grew up learning to use. The new load I worked up today is 62.0 grains of RL-17 with 230 grain ELD-X bullets. They're 2.852" cartridge overall length, CBTO measuremet is 2.102". Muzzle velocity with that load average is 2,790 FPS with single digit ES numbers. With the 230 grain ELD-X's having a G7 BC of .310 I had no problems shooting my 1,000 yard target with it today and consistently shooting under half MOA groups. I'm usually a big bore speed demon when it comes to cartridge selection but I really do like this short fierce little hammer of a cartridge! Below is my sight in shot today on my 1,000 yard target.
