[QUOTE="ridge rider, post: 764404, member: 17933"] Shawn, Would your secret patented modification to the "normal" 338 Edge chamber be nothing more than possibly introducing a bit of Weatherby free bore to lower initial pressures spikes to allow some more powder to be loaded over the load used in the standard 338 Edge case. This would certainly have contributed in achieving an estimated increase of possibly around 75 to 100 fps over the standard 2900 fps max loads you previously achieved in standard 338 Edge in a 30" barrel. No doubt another 4 inches of barrel length now at 34" over the standard 30" barrel would have provided another increase of say 4" x 35 fps increase per inch which would result in another 140 fps. If case design has not altered in size and volume as you imply; then may I kindly ask "are you still running the same loads or have you increased the load since you have some freebore to play with to lower pressure spikes for an increase in powder". How much more powder do you now load with? Also are you still loading with H-1000 or have you moved onto say a slower burning powder such as Retumbo or a double based powder such as RE25 or the new "unavailable" secret Hornady double based powder, both of which are known to bring on noticeable increases in velocity of around another 100 fps.. Also which brand of chronograph was used that recorded these speeds and the E.S. of those loads. Sounds like a great rifle build and certainly might have to order one of these going by the results published and seen in your video. Thanks in advance for your reply. TT [/QUOTE]
