Thread: Getting ES down with 223

Hmmm - I wonder if the 223 only runs sweet with certain powders. I can't provide any crony data but my heavy 223 I've used for F class and FTR (it'll shoot possibles with about 5X's to at least 600, I have the scores recorded to prove it). This is a good indicator of low ES.

This rifle came from Din Collings estate, with load data in Val's hand (bless them both) and I stuck with that load, 24.5 AR2208 behind Sierra 80's.

Now - the kicker, when powder got short I tried a couple of different ones, a cobber has used W748 in his 223 loads and they give excellent 100Y groups. My 223 would do the same, good groups at 100M with a couple of powders but not worth a damm further out - high ES.
