I wish I could tell you, but I'm still experimenting myself. So far I've tried IMI 62 gr FMJ and American Eagle 55 gr FMJ.  Neither was very impressive. :down: I've got about 6 or 7 brands and weights on the shelf to try. But the weather and other things just aren't co-operating for a range day. :shake:  I'm thinking the heavier 75-77 gr bullets might be the answer. But can't prove it just yet. 

I'm open to suggestions same as you. :shrug:

Hi all,

I have shot mine very little, but need to buy some ammo.

Is there a particular off the shelf .223/.556 that seems to be more accurate?

Thanks

AJ

I don't know the twist rate of your barrel my friend but I'll try and include a diagram that may help somewhat. Twist rates matter.

My ancient 16" Bushmaster Dissipator (from the days before RDS) has a 1:9 twist and definitely favors 55 gr bullets. I get stupid good results with 55 gr handloads using H335 powder.

I get reasonable and affordable accuracy from Wolf Gold 55 gr rounds. I'd be happy to give you a few boxes to try before you buy if you'd like AJ.

I've run a metric buttload of Wolf, Tula, Barnul, etc through it in classes and training.... while the accuracy is satisfactory for practice those steel cased rounds are still quite mediocre.
