Reloading advice Please

Hey guys, i have a .223 CZ rifle with 1-9 twist and a 20" barrel.
Just wondering what is the best powder to use and how much??? Will be using a 55 grain projectile.
I use the rifle for foxes but also do some 400-600 yard target shooting and thats all. Cheers in advance!

A stick/extruded powder in the speed range of H322 would do well. Stay away from ball powder; its track record for best accuracy is not all that great. Best accuracy means no worse than about 3 inches at 600 yards or about .3 inches at 100 yards.

That 1:9 twist is best for bullet weights around 70 grains; may be too fast for 55 grain bullets. So I suggest staying away from max loads with 55's and use reduced ones.

I've owned 5 or 6 223's with a 1/9 twist all were the most accurate(@100 yards) with the sierra 52gr match.

H322-, 4895, h335, CFE223, Benchmark, all good powders, but at 100 yards
give the Sierra 52gr match a try beyond 200 yards the sierra 69gr match
will do the trick, I've never found a 55gr to give me the accuracy I try for.

I used a lot of 2208, its made down there so you should be able to get it.
With 55 grain bullet I would start around 22 grains and work up from there.
It was a powder that was used in the light bench rest matches here in the U.S. for a while. When I shot in the Perth Matches it was the rage.

For 55 grain bullets that are standard. (Note that lead free 55 grain bullets are like loading for 69 grain standard.) I use Hodgdon H-335. It works so well it is all I use in .223 for 55 grain bullets.

For 68 to 77 grain I go with either Reloader 15 or Varget. I prefer the RL15, though Varget gets close to what RL15 does as far as accuracy goes for me.

I shoot out of a bolt action Savage Model 12 Long Range FVSS, with a 1 in 9 twist.

Ok no worries, and how much of the 15 do you use personally? I take it you start low and find what suits your rifle? Mine to is a bolt action

I agree with the Sierra Match, 52 Gr. using H332 powder. Even shoots well from a friend's old Mini14. .............. 24grs.
