Does anyone have a really great load for target accuracy in terms of brand of bullet, type of powder and grains and type of primers? I would truly appreciate some guidence for reloding the 5.56/223. I have reloaded thousand of rounds of pistol but never reloaded any type of rifle ammo. A little help please.
BTW, it is a 1:8 twist, true 16" barrel.

My favorite load is 26.2 grains of Win 748. It produces good velocity and outstanding accuracy with a vast array of bullets. I use it predominantly with 55 gr FMJ's, 55 gr Rem PHP, Nosler 55 gr BT, and my all time favorite, the 60 gr Nosler BT. I typically use the Rem 7 1/2 small rifle BR primer, but also use the Winchester WSP's when I can get them. This load generally produces sub-MOA in all of its iterations, through just about ant rifle I've used it in.

Hope this helps.

Winchester cases
Remington 7 1/2 primers
27.0 to 27.4 grains of Reloder 15
52 grain MatchKing's

This cartridge will pretty well measure the potential accuracy of your rifle. (Well really, you and your rifle.) 27.0 grains fills the case to the bottom of the case neck, 27.4 grains fills it to the top and it's too easy to spill at that level. 26.8 grains doesn't generate enough pressure to seal the case in the chamber well, the case body will have soot. Speed from my 24 inch rifle is a little over 3200 fps.

Reloder 15 is slow for this weight bullet, right on the ragged edge of usefulness, hence the full case. It shoots great.

77 Sierra Match King

24grn RL-15 or 24grn Varget or 23.2grn XBR-8208

LC case at 1.750

Wolf SRM primer or Remington 7.5

2.245 COAL


Typical Civilian Marksmanship Program / NRA Hipower competition load


eta: the course of fire is 200, 300 and 600 yards. About half the shooters do 77 for all stages (like me) and some do 80SMK for the 600 portion
