Dimpling of plated bullets (NOW WITH PICTURES!)

Different amounts of case mouth flare can result from slightly different cartridge case lengths. Longer cases are flared more; shorter cases are flared less. Slightly different case lengths in a batch often result from mixing different headstamps (manufacturing variance).
And under-flaring the case mouth will often cause bullet shearing. The flare can be increased by turning the expander die stem down in small increments until the desired flare is obtained.
BerrysBulllets usually have enough of a rounded base to seat without flaring the case, which is a very tedious operation in a single-stage press. (Not an issue in a progressive). However, every so often (say 1/100), a "fatter" BerrysBullet caused by a bit heavier plating may be encountered. Those bullets often shear when being seated.
Like most other folks have said here, those dimpled bullets will probably shoot OK within standard handgun hole-punching range, say less than 20 yards.

Poor Man:
To solve your primer problem, acquire a set of RCBS swageing dies to remove the crimp.
This is as fast as sizing the cases and will totally eliminate any primer seating problems. A slight more flaring will solve your scrapeing problem. At the seating operation shut the flare just enough to make the case straight since all these cartridges head space on the mouth of the case. You will be able to produce very fine ammunition this way :)

Thanks Shooter, SFG and Poor Man! I will take some measurements tomorrow and increase my flare a bit when I run my next batch. I need to get moving need to have a couple hundred ready to go for the DC Shootout at the end of the month. I also have several hundred 223 extreme bullets to get loaded.
FLY sorry to jack you thread! Glad I wasn't the only one having some issues today! :)

I know right?! I'm glad tstuart34 is getting HIS reloading problems solved. :laugh:

I will check the die. If the dimpling doesn't happen with other cases, could it be that these military surplus cases are a bit more stout and it requires more force to seat them? This combined with minimal flaring?

The Dillon dies come with both a round nose and a semi-wad cutter into the bullet seating die stem.

--- Quote ---We've incorporated a "flip-flop" seating stem and a clip that enables you to remove the die insert and change the seating stem from round nose to semi-wadcutter without unscrewing a seating stem out of the die body. We've always included both types of seating stems, but the new double-ended design makes it a simple matter to remove a pin,
