Thanks. I was incorrect about the balance point, actually 1" back from the fore end tip. As I'm a snowbird and only in WY until mid December I can wait for the new heavy duty Atlas as there is little use for a 338 RUM in Key West !
The newest data for RL 33 is now available from Alliant on line. The 338 RUM is not in the newest book w/RL 33 (338 Lapua is). They don't mention the bbl length, I assume 26". Ballistic twins, just different designs for different applications. The RUM works fine for me but I believe in a semi or full auto application the Lapua would be superior.
You might wonder how I extract loaded cartridges from my left port, left eject 6.5/284 action. You don't w/o removing the bolt. Empties come out fine. Only time I ever had to eject a dummy loaded round was when setting up seating depths. Pull the trigger, push the bolt removal lever and the bolt & cartridge come out the back.
(three hand would help !)
FYI the rifle was built by Scott Null in Driggs ID, great guy and excellent work.
The scope cost almost twice the rifle's price but .......
Have yet to try the Lehigh Defense 250 gr (ex Boretech) which Scott throated her for.
The 300 Berger is close but the Lehigh has a higher BC.
Thanks again for all the help.
