55gr CamPro .223 OAL?

[ReloaderRick]

Just wondering what the OAL should be? My first AR15 is in the mail, and just wanna have some ammo loaded, so I'm ready when it arrives. It's a Colt 6920.

It should tell you that in the reloading book. Or try hodgdons reloading.

Cam Pro doesn't have a book. That's why I'm asking.

I'm loading Cam Pro 55g for my AR/Tavor.
Load as long as can fit in the mags.
2.245" to 2.25" COAL to fit all my mags.
Some mags can load a little longer. I have 1 mag that will run 2.265"

 

[j_06]

same as any other 55 grain fmj, max mag length for an ar-15 In every reloading manual I own is 2.260.

Ok thanks, I don't have the mags yet, they are in the mail too, so I wasn't sure.

Or if it has a cannelure groove load so that it is centered on the case neck. Lots of factory 55gr is way shorter than the max length for .223rem.

That said lots of factory 55gr also groups rather poorly.

I would also just use the cannelure as a guide. Seating 55 grain FMJ bullets to full magazine length may not leave much of the bearing surface inside the case neck.

Most other bullet types I would seat to magazine length.

I would seat to crimp groove just like the hornadys.

+1 for centered on the cannelure.

I keep the case lengths the same or very close, and then load the projectile to the center of the groove.

I also use a Lee factory crimp die. My thoughts are that there is no way I can reliably load a 55grain slug to be close enough to the lands, so I may as well make them have nearly identical pressures when the bullet leaves the case.
