Rifle Bullet Seating Question

[cwbys4evr]

Hey all,
I'm trying to load my first rounds of 223 and having a problem getting the bullets to stay on the case for seating die processing. Are these case mouths supposed to be flared? Do I need to adjust the sizing die (RCBS FL Sizer)? Charging die? I'm clueless

Bullet Seating..

Most .223 bullets are Boat Tail. They have a taper at the base of the bullet. You just guide the bullet into the case as you raise the ram of the press into the seating die.

If your bullets are Flat Base, it does help to chamfer the inside mouth of the case with a deburr tool...Bill.

did you slightly chamfer the case mouth?

flat base bullets I take it, you may have to guide the projectile into the die with your other hand while working the press...at least on a single stage...once it's in the die it will center itself if all is right....

I give mine a little tap in the die lower the ram a hair then seat. Doing let it max out the powder die ether or it will crimp the case mouth closed.

Billybob44 says it well. Just chamfer the inside of the mouth evenly and then guide the brass and bullet into the seating die, just make sure you get your fingers out of the way. Decades back I got my finders pinched pretty good on more than a couple of occasions, ouch! I chamfer all my mouths a bit just to make seating go a little smoother.

Like they said, on a single stage it is pretty easy to get your fingers out of the way, I will let you know how it works once I get my conversion kit for the 650.

Most .224 bullets are not boat tails... in fact a good many of my loads for 5.56 and .22-250 are flat based bullets. I've found flat based bullets to be more accurate out to about 200 yards in 4 separate ARs. Just sayin'.

Yes, there are a lot of boat tails too, and they are easier to load for sure. For flat based bullets I just give it a little extra on the chamfer. It also helps if you're loading with something like the Hornady New Dimension dies that have a moving guide for the bullet that holds it perfectly straight.

I use Lee dies for everything on my 223 except for bullet seating where I use the new Hornady die that has the collar that the bullet enters that keeps it aligned with the case. Very easy regardless of boattail or not.
