I use 4895 for my 150gr FMJ .308 and am going to use some 4064 on some 168gr BTHPs...
any input would be great...thanks.
Oh these will be surplus / ZOMBIE / plinking rounds....
IMR Powders for 223 with 55 grain bullets I would use 4198. I have had good luck with this powder with bullet weights from 40-60 grains. I'm sure IMR 4895 is excellent but I use H4895 instead(different charge weights not interchangeable) because I like the small extruded kernals. IMR 4064 is still a very good powder despite the fact that Varget and XBR 8208 are surpassing it ballistically and are better rated for extreme temperature swings. I have yet to use the XBR 8208 but if it's half as good as everyone raves about than it means only one thing- a single ragged hole in the target and the tighest groups so long as you do your part. BTW 3031 is excellent for heavier weight 223 bulets like the 75 grain OTB, even stabilizes 75 grain OTB's in a 1:9 Twist barrel.
