Charles -
A point to the records that I think your missing is, what calibers are breaking the records currently?
Most all the records you listed are several years old now and have not been broke by the calibers that set them either.
The records are cool and great that I respect very much, but they are far and in between, and more of a rarity.....
Whats better then the records is what is currently winning the most matches, winning the current club aggregate standings, and placing the best at the current National/World/State events.
As much, and as fast as the sport evolves with bullets, brass, barrels, rests, bags, components, calibers, etc... what was "hot stuff" 3-years ago is almost old news, let alone what was being used 5, 10, or more years ago.
So what are the current standouts? Are they a traditional LR caliber? Are they old LR potentials now revolutionized? Are they a holdout that was in need of "now" better components? Are they a whole new deal/caliber?
Then, what calibers are winning the most at all the ranges combined, from the North to the South, to the East, and in the West?
And what were the standouts from the top-20 for the past couple, three years at the National/World/State matches, where so many ranges and shooters are represented and gather in attendance?
Here is one current 2012 standout that I am aware of:
Sally Bauer is on a "12 in a row" LT & HV win streak <><> 6 relays + 6-shoot-offs <><>
She has had a stellar 2012 season all together, with many more wins in the books.
What ever all components her equipment list is all sporting, we can say is "hot stuff" right now !!!
Another is the almost predominance Top-20 the 6mmBR-Family had the past 2 years of 600yd-National's.
Advise to the "new guy" I feel would be better served by advising what is hot now, not a one-hit wonder like Tom's 300-Hulk of 6 years ago.
Happy Shooting
