I have some Speer .223 brass that I want to use for 55 fmjs. The resized lenght varies between 1.740 to 1.759. I should mention this was fired out of LEOs M4s.
I'm thinking of just trimming long ones to 1.750 and leaving the shorter ones as is.
Now I want to get the best group I can using H335 out of a carbine but does a difference of .010 between 1.740 and 1.750 gonna make a much of a difference accuracy wise? Yeah it's just plinking ammo but I'd like to get as good a group as I can to 200 yards.
My other option is to separate cases according to lenght but I got over 1000 cases and don't look forward to checking each one.
Ideas? Thanks for looking.
