And both the magnitude and sense from the zero change is rifle dependent. I did surprise a tiny bit with regard to the methodology bringing about summary that variations in temperature on the scope on your own experienced no considerable affect on zero shift.
I are making use of H4831SC in my 7 mag with fantastic final results. There usually seems to be some around the shelf and it is actually a flexible powder.
Amazing write-up Cal. I tried A number of powders in my 6.5 Creedmoor and located H4350 to generally be probably the most consistent. I live in Phoenix where by the inside of my truck can certainly strike 140 F. I’m happy to check out they deviation is so reduced.
I'd Feel in many cases the temperature with the ammunition is identical at that in the rifle and scope.
Groups weren't recorded as I was trying to find the photographs off as my timer went off promptly to make sure that a “incredibly hot chamber” or “this, that, and one other” didn't mess up the outcome. Thanks, Patrick

but once you are away from that place if gains and looses speed. Tests reveals points ar enot linear for many powders , some have sure temp ranges where absolutely nothing Substantially comes about and afterwards a steep drop or climb ,you might avrage that but its not true.
Thanks Cal, It’s currently preordered and I’m really on the lookout forward to beeing stunned! Transpires to generally be beautifully timed, considering the fact that I’m at present contemplating spending money on a far more complex annealing set up, and It might be brilliant to produce this conclusion depending on right facts.
