.458 bulging Starline

[laowho]

Thanks Kurt. Seems the bulge was the flare carried all the way down the length of the seat in the bullet. I took a new case, took out the flare (resizing die), dry loaded a bullet and it seated all the way down w/o a bulge. Had to seat it to an OAL of 2 15/16" to have it fully chamber. Does this seem short to you? Whatever the case, glad that I can load the .458 bullet w/o flaring the case, and that I can use the brass I have. The BACO ammo I got also uses S'line brass and the front driving band on the bullet is at least as large a dia. as are the Chey Bullet .458s I got. And know these are true cuz I ran 'em thru the bullet re-sizer (.458).

One thing tho...if I'm limited to 2 15/16" OAL, how in the world do I get 70 gr powder in for a 500 gr bullet?

Just read yer 1st post--no, compressed .15" after drop tubed. Not a special PP chamber. Seating die is properly set. Also, am tryin to load w/o crimp, but the taper die does work.
