I'm fixen on ordering some 223 bullets from Widner. The ones I'm looking at give me a choose, with or without the cannalure. This load is for one of my AR15,s. I have been shooting the 62 grain military stuff (SS109 I think). It's shooting about 1moa with iron sights at 100 yards. The bullet in this military stuff is cannalured but thought if it would be needed for my handloads.

Another question.... Would the 1 in 9 twist in my AR work with the 55 grain bullet?

Thanks Guys

I don't use cannalured as a general rule .
They aren't as accurate as ones with out . HPBT 55-70 grains work very well in my BM . With 69 Sierra's being my particular cup of tea .

Shoot Straight Know Your Target . ...

My buddy and I have RRA 1in 8 varmint rifles. We have shot everything from 52 to 80 and got Moa or less. No need for a cannalure on a 223. Given a choice I'd opt for no cannalure.

I'm kinda new to be jumping in on this one....but if you are going to measure and set your own O.A.L. to fit that gun, the cannalure might not wind-up in the right spot anyway.

The 1-9 twist will work with almost any bullet providing velocities are kept reasonable. You'll run into trouble with the 40 & 45 grain pills because you can drive them fast enough that they'll be over stabilized (over rotated) and fly apart. I've seen it happen with the standard 1-14 twist too when maximum velocities are reached.

Without, definitely.

If you want to seat the bullets without a cannalure, and you are going to use the ammo in a semi auto, you will want to use a Factory Crimp Die to keep them in place.

As far as I know, only Lee sells any, but the ammo factories get them from somewhere, maybe they make their own.

no groove if your loads don't need it.

I don't crimp mine and run them through an AR15 and have never had an issue about the bullet moving.

I taper crimp my .223 as everything gets fired through AR type rifles. Never had a problem with holding the bullet in the neck of the case when there was no crimp groove.

BUT every rifle is different. Try it and see what happens.
