I came across a box of Winchester .224 , 64 grain SP bullets I want to load up for my AR, 1/9 twist
I also have a 20 inch 1/7 twist I'd like to run these in.
I would like to use IMR 8208 XBR powder if possible.
none of my 4 manuals list a 64 grain bullet for 223 Remington
IMR's data base only shows some 63 grain loads starting at 21 grains
