Bbassi: I am guessing (because you don't say) that you are reloading cartridges in your friends Rifle which is in 204 Ruger caliber?
I have been shooting and reloading Hornady brass in my 204 Ruger's since, literally, day one (2,004) - I have yet to suffer my first split neck with Hornady brass.
I have seven Varmint Rifles in caliber 204 Ruger and the only reason I use any brass other than Hornady is simply to help keep my brass segregated (dedicated) for a particular Rifle.
I very much enjoy Hornady brass in several calibers and actively seek out "deals" on them.
Which brings me to the only shortcoming I can see with Hornady brass - its expensive.
I am guessing you have a reloading problem either with your dies or with lubrication - it is a possibility that the chamber on your friends Rifle is flawed.
Hope you solve this situation!
My experience is the Hornady brass is good stuff and lives long.
