[QUOTE="Tumbleweed, post: 890692, member: 9281"] Jeff, you really hit the nail on the head in regards to impact velocity. The full custom that I just finished a few months ago was almost a big .338 of some kind. I wasn't financially prepared to step up into a Cheytech based case or do something like what you have done with your .338. So, I was looking at probably an Edge in a Rem 700. I consulted with a couple people (gunsmiths/machinists) in the know about what was possible with a 300 RUM and 230 Berger Target as far as velocity. I was hopeful to get close to 3150fps with a 230 and when comparing that to say a 300SMK at 2850fps I wasn't giving up anything as far as ballistics. So, I designed a custom chamber with special throating, 32" Broughton 5C 9 twist and with RL33 am achieving a solid honest to goodness 3250fps with the 230 with NO pressure. Accuracy is well inside .5MOA. Now, when I compare those ballistic numbers (velocity and energy) to a 300 SMK at 2850fps I have a pretty big leg up even past 1500 yards. Comparing my 230 with a 300 grain OTM at 2850fps I still have the edge by 155fps and am only shy on energy by 77 ft.lbs at 1500 yards. Now, I may not have the sheer bone smashing mass of a 300 grain bullet but this should accomplish my purposes with very good impact velocity at long range. So, in essence I'm doing the same thing that you are doing, just on a smaller scale.:D [/QUOTE]
