It's not equality in Sherri's case, it's the gene pool and DNA chain. Plus the skills and knowledge passed on and from her Mom, sister and stepdad.Did you notice the record-setting team had two females? And that they both posted perfect scores. It was two male shooters who dropped points. So much for equality.
Note the service rifles put about half as many shots inside the 10-inch X-ring on that 1000 yard target. And the scoped bolt guns dropped only 3 points while the service rifles dropped 46. Some of the service rifles probably put a shot or two in the 8-ring which extends from 33 inches to 44 inches in diameter; the 9-ring goes from 20 inches out to 30 inches diameter. It's hard to get exactly the same sight alignment and sight picture using a post front sight and an aperture rear for each and every shot. And those service rifles have at least a 4.5 pound trigger while the bolt guns can have any safe pull weight; they're usually in the 3 to 5 ounce range.the second part about service rifle was also super impressive, iron sight, same distance? all within MOA!
I doubt barrel life will be any different; it burns the same amount of powder per shot.Interesting long range caliber, I was not familiar with it...Less powder than the WSM, and similar velocities...should be better for barrel life. How much, I wonder...
The US Army Rifle Team feels it's the arrow. Here's why.It's the archer, not the arrow. Also helps that they shoot year round.
Case Efficiency, Charge Weight and Barrel Life
The 7mm SAUM case holds 7.4 grains less powder than does the 7mm WSM, but the 7mm SAUM has proven to be more efficient than Winchester's short magnum. This means you can almost match the velocities of the 7mm WSM (with the same bullets) using slightly less powder. Using identical powders and the same bullets, Steven Ikeda has found that his 7mm SAUM can match 7mm WSM "book load" velocities with about 7% less powder. In all respects, that's a good thing. Short Magnums are "overbore" cases with notoriously short barrel lives. Burning less powder should give the 7mm SAUM a barrel-life advantage over the 7mm WSM, and of course, the SAUM costs a bit less to feed. Plus powder charge weight does figure into felt recoil, so a 7mm SAUM will exhibit slightly less recoil than a 7mm WSM running the same bullet at the same speed.
At the 1902 Palma Matches in Canada, the US Palma Team had 6 members using the .30-40 Krag and 2 using prototype 30 caliber rifles based on the Mauser 98 action design (royalties were paid to Mauser). It shot 220-gr. 30 caliber bullets out at 2300 fps and later would be dubbed the M1903 and the cartridge was the .30-03. They didn't shoot as accurate as the Krags and the US team lost the match. The team from Great Britain won the match with their .303's.When the U.S. army adopted the new .30-03..they found that the older .30-40 Krag beat them at long range. Their answer? The krag was not permitted to compete against the new Springfield. It wasn't until the 06' round came out that the Krags accuracy was bettered.
