reloading 223 ackley improved

I just reamed my savage to a 223 Ackley Improved. Anyone load this round? Got any interesting recipes?

My rifle tends to like heavy bullets, from 64 to 75 grains. Before the reaming I was normally running 25 grains of W748 behind a Sierra 69gr MatchKing as my accuracy load.

Two loads to try one is XXXX of IMR 3031 is has worked well for me in both 223 Rem. and 223 AI when fired from a 14 in. contender. Another powder well worth trying especially for your heavier bullets is H335 start around XX grs. and work up from there. Hope this helps. Enjoy Your Shooting Time, Tom ( TGC)

I hope you didn't find you had a headspace problem...

You didn't mention setting the barrel back 0.004" to get the correct AI headspace. May I ask how you headspaced it?

Thanks,

Tom

Swifter, I dropped the reamer and rifle off with a competent gunsmith.

It seems to shoot just as accurate as before. I worked up a new load for it for my 1-9" twist barrel. I don't have velocity numbers yet, I need to take my chrono out to the range.

Before and after loads are using Remington brass, Remington 7 1/2 primers, and win 748 powder with a berger 64grain MEF bullet.

my "pre-improved" load was 25.0 grains
my improved load is 27.5 grains.

I ran tests up to 28.0, no signs of ill pressure, but accuracy dropped off. At 27.0 and 27.5 I got five-shot groups of .4" at 100 yards.

Latest test, I now have a load for the Hornady 60 grain V-max. I'm using 27.0 grains of Win748 powder and got a .25" group 5 shots at 100 yards.
