Just wondering if any of yall have loaded with the IMR 4064 for both calibers & how yall liked it. I was trying to find one powder to load both 5.56 & 6.5cm.
The LYMAN book is where I got the IMR 4064 info from.
Accurate has some too. I was reading on some forum last night & a guy was using a chronograph with the AA4064 & IMR4064 for both 556 & 6.5cm. Said the IMR4064 worked best for both & the AA4064 slowed the speed down by 50ish fps. On the 6.5cm.
