pushing a little flare for the neck of the 223 round for bullet to seat a little? I am having a lot of problem with my 55 gr bullet. But I had no problem with the 62 gr ones.
No, I use the Speer reloading manual to put the depriming die on. It sized the neck fine for the 62 gr bullets. But too tight for the 55 gr. Not sure why it's that way. I hope the Forrest brand can work like the Dillion one. I am not going with the RBCS one anymore, the depriming pin kept breaking off.
So---both of your bullets are .224 in diameter and I assume they both are boattails so shouldn't make a difference. If you chamfer the casemouth both will seat better.
Forrester sizing die will not flare the casmouth either---broken depriming pins sound like you are depriming military brass or are not getting the cases aligned properly in the shellholder.
.223 bullets are actually .224 diameter.... i think your bullet design changed and thats they problem.... you went from a 62 grn with a boat tail, to a 55 grain with a flat base didnt you?
cham that case mouth and hold the bullet as its goin into the die...once again i love lee dies i havent had one problem with them.......ive had more problems with that rcbs crap.
As others have said, you should put enough chamfer on the inside of the case mouth that the bullet will just barel sit on it. Use your fingers to guide it up into the die and use a slow, smooth motion. You shouldn't have any problems.
I too went through this when I switched from 52gr. match HPBT's to 55gr. Hndy SP's w/ a flat base for plinking.

no cham dies its a little cutting tool that puts just a tiny bevel on the inside of the case mouth allowing the bullet to......kind of rest on that surface......go out and but a different reloading book.....layman 49th eddition....IMO best book out there. worth the 22$ i paid for it
I don't want to offend you, but if you don't know what chamfering and de-burring is, you should stop reloading and put some more knowledge under your belt before continuing.
i agree with sam i dont wanna offend you but....do more research google is your friend knowledge will save you from injury in this case. Reloading isnt a joke you can really hurt yourself loose an eye etc.......
I use the speer manual and it explains chamfering the i.d. and deburring the o.d. just like any reloading manual. Also make sure ur cases are lubed good when resizing and depriming. I use all rcbs equipment and never had any kind of problem.
Over-lubing OR getting lube on the case shoulder will cause this. It's not fundamentally bad, as it will 'pop' out when you fire, but is hard on brass and could slightly up pressures.
