Brass Neck rubbing copper off the bullet when seating?

[BeagleBoy360]

I bought a pack of 500pc Hornady Z-Max 50gr bullets because the price, now from my understanding, these are just the V-Max, just with a yellow tip and a tad bit cheaper (makes no sense)

Anyways, i started loading up a bunch today, and it took me a while, but I started to see copper shavings on my press, and realzing that when i seat, the neck seems to rub some copper off.

The necks and bass have been fully resized by a RCBS die, Ive never had this happen before. Is this common, or did I get maybe a bad batch of projectiles that the copper is too thin/soft.

The picture of the bullet after being pulled, it was pulled with pliers so dont mind the deep marks on top.

You need to chamfer the inside of the neck ..

I thought I only need to do that if Ive trimmed the case down.

If there is a sharp edge around the case mouth that is shaving brass then you need to chamfer.

I chamfer every one of my cases as a standard case prep step.
It facilitates a smooth,consistant,straight seating of the bullet.

I once purchased 120 rounds of loaded ammo at a gunshow.
I bought it simply for components. When I pulled the bullets, none of the cases were properly chamfered. Every bullet was significantly damaged!

I got a great deal on the brass, but the bullets and powder went straight to the garbage! What a waste!

Yup chamfer the neck on new brass. Food for thought Lapua brass comes chamfered ready to load. Chamfering 100% improves seating.

This is all fired brass, which is why i was so confused about it being so sharp.

Good to know.

This situation should make more of us aware of how some manufactured ammunition is such poor quality! Its no wonder why "some"
Ammo shoots so poorly!

Get a VLD chamfer reamer. Lyman has hand held ones for like $15. Never look back.

I use the hornady case prep trio. Smll cheap and works
