Hi, I have Hornady"s 300gr HP/XTP (.452") Bullets I'm getting ready to seat, when I found them to have two cannelures. I would assume that the first one, closest to the pointy end is the one to crimp into. But, I'm not sure. If the first is the one to use, whats the other one for?
OH, I almost forgot, I'm loading .454 Casull for a Ruger Redhawk, 7 1/2" barrel.
Thanks Bob

My guess, since the Casuall was developed in .45 Colt cases, and is the 1/8th inch longer... BS, you can crimp the Casually cases in one and the .45 Colt in the other... Many .38s used to have 2 grooves for use in either .38 Special or .357 Mag. Luck.

Just seat the bullet to recommended oal per the manual and crimp there.

iiranger: I was thinking about that myself, but, also thought it might be chambered in some rifle.
Thanks for the input


juggerenaut76: Nether cannelure gives me the COL that the Hornady book calls for. Close, but no banana. I could pick the one that comes the closest to the books COL,OR, maybe wait till Monday and call hornady.

Thanks for the reply

What the Hornady book calls for is unimportant. Measure the length of your cylinder. If the cartridge will chamber without affecting cylinder rotation, it is the right length, as long as the charge isn't heavily compressed.
