Duplicating factory load

Dont blend powder without a pressure lab

I should not let this be known, but some of us did. I can say that I will not again except for different lots of the same powder

Bullets with cannelures are seated and crimped into the cannelure without any regard to accuracy lengths

seating depth is probably your best tuning tool

Well I took some 50g vmax that I load with H380 that I was able to locate. Right off the bat the groups were better then the 55vmax
I Chronographed the last 5 factor loads out of the box and they were 3810-3864
The loads I loaded grouped better the my 55g hand loads but these were loaded with h380 that I was able to find.
I was trying to get to the speeds that gave me that great group but I started getting ejector marks at 39.5 g and only getting approx 3700fps.
I might try cfe next but not sure if I can reach the speeds of the factor with my 20” barrel.
Starting to wonder what powder may get me there without buying it lol
