I’m helping a friend of mine that wants to build a 25cm and am trying to find the neck measurement of Alpha 25creed brass loaded with Berger 135s. If anyone has or can get those numbers it would be appreciated.
I am also trying to track down reamer prints of what I believe is the 3rd and final reamer print that blackjack put out before they went under. If I’m wrong on that please correct me. I have read where there is a .115 freebore and a .130 freebore. I’ve only been able to locate the .115 freebore prints.
Ultimately he wants to run the 135s around 2850-2900 in a 22 inch barrel if possible because he will be running a suppressor full time.
Thanks
