IMR 4064 & the .243

4064 works well and gives good accuracy.
Varget is a little better and H414 best in my experience with the 243.

H414 meters well and gives great accuracy at max velocity - my only problem is that I believe it lead to hard powder fouling with some max 70 gr varmint loads in a 6mm rem Ackley Improved I had.

my .243 love the imr 4064

36.5gr of imr 4064 with a berger bt 90gr , primer cci br2 and lapua case

or

36.5gr of Varget with a hornady v-max 87gr , primer cci br2/#200 hornady/lapua case

but i don't have a chrony , i don't know their real velocity but those load are near .5 moa group
 
never used it, im into the varget for my 70 grn match and some 85grn im using H4895 and im trying out some H4350 atm, all my sierra bullets can go through the same hole, my gun chronys slower then book at 3300 down to 3108fps
 
Had good results in my browning with 100gr sierras and around 37 gr of 4064. If I recall it was around 2950 on the chrony. I had better luck with IMR 4831 but 4064 is a close second. Sierra guys told me it is their go to powder when ever someone asks about a .243 load.
