I'm slightly sceptical on some of those figures from quickload. I have pointed this out before and I believe boyd allen has pointed this out on another type of powder that is marketed under 2 different brands. H4350 says 3760 right, if you look up quickload for ADI AR2209 (the exact same powder where it is made in Australia) says 3990 I believe. Obviously this was a different batch but it shows how the exact same powder can be either 3760 or 3990 depending on batch.
This has a massive implication on the barrel life calculator depending on what figure you use 3760 or 3990 and I have seen all over the internet where people talk about how "cool" burning H4350 is with the 3760 figure. The reason why I questioned all this in the first place and went digging is H4831SC which is the slower burning powder but shows a higher heat than H4350 at 3870 according to quickload. This would seem that H4350 should give better barrel life than H4831SC at equivalent pressures. I'm not so sure I believe that.
