Thank you AJ. Do you normally find the chamber pressure predictions to match the point when you start to notice actual pressure signs?
I wonder because 96.0gr Retumbo is the load I use in my Surgeon XL .338LM. I've never noticed any serious pressure signs, certainly nothing that would indicate 73kPsi IMO. That's interesting.
I'm shooting at about 6400' asl, and normally in about 35-50degF conditions. Does that have much effect on the pressure?
Thanks for any insight.
Here's the rifle in question:
PAI .338LM on a Surgeon XL
30" Rock 1:9.4
300SMK, MV 2925fps avg.
The reason I'm interested this thread and data is because I just recently bought another XL .338LM for the sole purpose of cutting the barrel down, and wear my suppressor full time. I've been thinking around 22-23".
What do you think about it? Would it be better to leave it a bit longer around 25-26"?
