A reader posed this question and it is complicated enough to warrant a column, so here are the answers, and yes indeed, there is more than one answer.


Dear Sir,
In reloading .223 Remington I am using 24.5 grains of H-322 powder with a Remington 7-1/2 primer under a 55-grain FMJ bullet usually in a Federal case but occasionally in GI cases. I have been doing this for about 10 or so years. I am shooting them out of a Colt LE Carbine and a Ruger Mini-14. They have proven to be quite accurate.

Now it seems about every loading manual except the Speer No. 12 book rates that load as too hot or doesn’t list it at all. Speer No. 12 was the original source for that load.

I realize the components used by ammo manufacturers will obtain specific results and are not available to me. I was trying to get close to the 3,250 fps listed by Federal (ATK).

Why is that load suddenly unsafe? Should I change the load? I have about 1,100 or so of them loaded.
Respectfully,
Fred
