Thanks for your detailed response
Your welcome. No big thing, just a copy and paste from the write up I did last year.
I don't mess much with 223 load development work any more but in the past have experimented to the tune of over 2500 rounds of handloads.
Of course they were for a specific rifle, but some general observations (and your results may differ) were that 335 and BLC-2 worked best near max pressures and with bullets of 50 gr or more. I got better results with the lighter bullets with H322 and 4895.
If I could have only one powder for the 223 it would be 4895. Works well across all bullet weights and delivers consistent results and good accuracy when the right combo is found.
Actually, If I was told that from here on out I could have only one powder for all my reloading (223, 270 Win, 7-08, 30/06, 7.62X54R, 7.5X55 Swiss, 303 Brit, 308 Win and 45-70) it would be H4895. The only caliber that it is not very well suited to is the 270 Win and it will work at least passably in it :grin:
