Reloading

[CZ527 Guy]

I just got 300 - new 6mm ARC cases made by Star-Line Brass.

I ordered them from a place called "Druid Hill Armory". The price was $0.65 a case in that quantity. It would have been $0.75 a case for a bag of 100 cases.

I'm going to get started on them today, trimming to length & chamfering the inside and outside of the case mouth. I'll be reloading with Hornady 6mm 105 grain BTHP bullets and 26.8 grains of RL-15. I use CCI primers.

I found that after 5 reloads, my Hornady cases would no longer maintain adequate neck tension. I neck size only but do not anneal.

I hope the Star-Line brass will give me more reloads. Time will tell.

Neck size only? I have to ask what rifle are you working with & how is your bolt closing? Have to ask as Head space tends to grow with each firing. My understanding is most folks who neck size only, (A minority of us reloaders) find they need to full length resize by the 3rd firing in order to get the bolt to close. Feel free to correct me if needed.

I would expect similar performance from the starling brass VS the Hornady offering.
