Fifty,
I apologize if this has been asked before, but what kind of velocities are you expecting to achieve in reasonable pressure loads in the 300 Allen Express based on the 338 Lapua case with the WC 265g and 290g and 30" barrel?
Sounds like from Jon A's post that the 290g ULDRBBT will need a 1:8.3 to stabilize while a 1:9 will work on the 265g. Sound right?
Thank you.
