What is your go to recipe for loading FMJ 55gr in .223/5.56 particularly for AR type weapons? I've loaded some but would like to tweak just a tad.
Pet load for 55gr .223/5.56 ?

1. 25 gr H335.
2. 24.5 gr SW Tactical Rifle
Both rounds at SAAMI max length. Armscor FMJ's, SB sized once fired R-P brass, Federal GM205MAR primers.
Both produce excellent results. The FPS difference between powders was inconsequential. RCBS 10-10 weighed. Tried and found SWTR to meter like a dream but the slightest breath of air will scatter the powder. We do 50 rounds at a time checking before we start and 60% complete using Frankford arsenal Platinum Series (check all screws at least every 400-500 rounds).
By excellent results I mean sub one inch using Savage Axis bolt gun.
There are other solutions of equal accuracy. Difference is that cost per round thing. Watch Grafs and MidSouth for SW powder.

26.0 gr Varget. YMMV, please work up from starting loads to your desired accuracy or velocity node.

Don't load any fmj's, but for 55 grain sp and both varmageddon hp and tipped, 24.8 gr imr 4895 gives under 3/4 inch groups @ 100 yards in a few different ar's I run them in.
And definitely agree with MUP on working up your loads.

25gr H4895, IIRC. Same as above on working up

Thanks, guys! I have all those powders. Now I just need AL deer season to be over so I can use my range. I don't hunt my property but let friends take their kids there to kill whatever they want so I won't go over there and shoot until end of season.
