Question RE IMR4320 and QL vs. developed load. Developed load in this case equates to no traditional pressure signs of increased bolt lift or primer pocket looseness, after multiple firings.
My developed and chronographed load with IMR4320 gives a good bit more velocity than the same powder charge theoretically gives via QL inputs for my rifle and fired case.
I know where I WANT to be on this issue. For a hunting load in the field I want to bring as much to bear as possible in a safe load, which I feel is what I have done from years of safe loading experience in working up this load.
Where I SHOULD be on this is what I am searching for.
Can a safely developed load that exceeds QL predictions truly be called a safely developed load? Are there such things as "fast" barrels that we hear about?
Love my 130 TTSX load. It is fast, accurate as shown by the 300 yd group in a previous post above, safe by traditional pressure signs, and did I say accurate?
Thoughts? Thanks guys.
