I am loading a few thousand .223 . I was planning on keeping them in an ammo can and just taking the whole can to the range when I go . I am loading a 55 gr fmj bt bullet . The bullet has no cannelure . Should I be crimping thes bullets or not ?

I never crimp .223, but I only load match grade bullets without a groove. Others will say differenty;)

You don't have to crimp them. I like to crimp my blasting/plinking/must work ammo, so I would use a taper crimp on those bullets with no cannelure if I was to crimp them.

No need to crimp .223 for use in an AR-15 unless your gun or magazines have a feed problem that drives bullets into the cases.

If you have proper neck tension it will take 60+ pounds of force to move the bullets.

If you feel you must crimp, get a Lee Factory Crimp Die and you can crimp them without harming the bullets or buckling the cases like your seater die will do.

I'm curious though, were you found 55 grain FMJ-BT .224 bullets without a cannelure?

I got them on graf and sons . They are a priva brand bullet and they were the only ones who had them in stock so thats what I bought . I think they were around 85.00 per thousand .

Will the bullet sating die on my RCBS dies work for taper crimping ?

Not really.
Rifle caliber dies roll-crimp into the cannulure more so then taper crimp.
The seating die crimp is totally dependent on exact same case length to work.
If the bullet has no cannulure for the roll-crimp to go in, the case shoulders will buckle and the ammo won't chamber.

As I said earlier, if you want to crimp smooth bullets, get a Lee .223 FCD.

No cannelure, no crimp.

Taper crimp will work if you want to crimp them. ;)
