"I just read that eley has a patent on it (glass in the primer mix). "

Got my doubts about that. Its a common practice in that industry.

I would be happy with 100,000 if it's still accurate that'd be awesome. Thankyou all

It's really not something I would be worried about - I have an old Brno Model 1 that my Dad bought in 1947 - it can still shoot groups at 25m that can be covered by a man's shirt button - edge to edge (I'm guessing 7mm, maybe). It has had every form of ammunition known to man fired through it.

A quick search shows that glass has been in primers for many, many years, so I am personally not worried.

eg https://www.bevfitchett.us/chemical-ana ... tions.html

Anyway, you COULD buy a CZ 455 with 3 or 4 spare barrels and swap them out every 100,000 rounds or so - your kids may still inherit 2 or 3 of them :D

Just buy and shoot it. If you wear out the barrel you have done you fair share of supporting the ammunition manufactures and I am sure have a good time doing it. Bigger fish to fry like, rust, government and the wife wanting more than you.
