I did a post recently and I said I used IMR 4350 because it has lower pressure with the same velocity but I was wrong It took me a wile to figure out what I used when I was shooting  my 1904 Mauser it was H380 that is the one that has low pressure and still a good velocity ... I like IMR4064 when I shoot 30-40 although H380 turned out to be very accurate ... It took me a wile to figure out why I loaded 8MM with IMR4350 and I remembered Its because my 8MM has a 16 1/2 inch barrel and IMR4350 being the slowest burning of all the IMR powers it gives the nicest fireball when you shoot it and looks very impressive at the firing range ...
