loading 223 using cannelured bullets ??

[357shooter]

If I use bullets with a cannelure do I need to crimp them or can I load above
or below the cannelure. this would be a 62gn fmj. Thanks for any help.

You don't have to use the cannelure... I do just to make it easy, and lightly crimp just because.

I always crimp if I'm handloading for using my AR, when I use to have my bolt action I never crimp.

If loading for Semi Auto most people use the cannelure and a light crimp to keep the bullets from getting bumped deeper from the action.

If loading a semi auto one at a time or a bolt action most don't crimp.

There is no reason or need to seat at the cannelure unless you are crimping. If your not crimping, a bullet W/O a cannelure would probably be more accurate.

The cannelures are there to prevent setback in magazine fed semi-autos, since pushing the bullet back can cause an overpressure situation. A slight roll crimp into the cannelure is all it takes to get the case to dig into the knurls of the cannelure.
