Do I need to use only bullets with a cannelure for my AR-15 (M-4) ammo or can I use plain bullets? I recently bought 660+ Nosler 55gr tipped Varmagedon bullets. If they don't shoot well in my two 22-250s I'm hoping they will work without problems in my AR.

Never shot a cannelured bullet in an AR in my life.

Never crimped any AR round in my life. Granted I go for 100% case full of powder and I know what neck tension means, how to get it and how to use it.

YMMV.

My BCM loves 53gr V-Max and 77gr TMK's.

Thanks for the replies. Dave
