AA2520

[Alaska]

Does anyone use AA2520 with 69gr MK in their M4?

What load do you suggest?

Thanks

I use 2520 with surplus 62gr green tips with great result, and used to use it with 80gr Matchkings. I had better luck with 2460 when I shot a few 69s, sorry I'm away from my notebook right now so I'll have to look up the specifics later. As a general rule 2460 has been more comsistent for me that 2520 as far as 223 is concerned.
