243 IMR4064

[George Foster]

I was wondering what everyone's experience with 75 or 85gr bullets using IMR4064 has been for accurate loads.

I have used it for 80g and bigger bullets and had good luck with it.

I've found it to work very well in 10 Twist barrels under 26". Weigh each charge though! It doesn't flow all that well, but the results can be well worth the extra effort. JME WD

I have had better luck with 4895 and 4350. In most of my 6mm guns they just seem to do a little better. Matt

Excellent results with 85gr Sierra out of factory 1 in 9.125 twist.

I have had a .243 for around 25 years that would shoot absolutely terrible unless fed IMR 4064 and Speer 85 Grain bullets. Only until recently did I try a bunch of the newer powders working up a varmint load and found Reloader 15 to be the new "wow' powder with V-Maxes.
