You can eliminate the dings in new brass mouths by running them thru an expander mandrel in a 7/8 x 14 body sold by Sinclair or K&M; about $30. Even if you don't turn necks, this will make them more consistent when passed thru the bushing.

The brass is brand new so I did not think to resize it.
Forgive my ignorance - I consider my knowledge just past beginner when it comes to reloading. Is that something that should be done automatically with new brass or just when there are issues.

i wouldnt consider loading them without sizing. some are pretty dinged up...

A lyman M die is alot cheaper than the k&M and works perfectly...I have both. Re the 77 grain load with the 180ttsx....I will be shocked if this winds up a "max" load.....he'll probably wind up at 80-81 grains as hodgdon lists 79 as max with a 200 grainer.

I encountered the same thing you did, and then I found the cause. Check this link, and you'll see how I discovered it. Bullet Shape When bullets are made on different machines, the ogive can be quite different, even when they appear identical. This is especially common when switching to a different box (or different lot) of bullets.
