Factory pipe? I'm waiting on a CTR from Euro Optics and hope the throat and magazine will allow me to shoot these 88's in it.

My CTR 223 had a very short throat. It’s a few years old, so maybe they’ve made some changes, but you may need to extend the throat a bit yourself for the 88s to fit and not eat a ton of case capacity.

I’m curious what kampfeld charged to add freebore if you don’t mind sharing? I have a 6.5 prc with short freebore. Factory ammo is into the lands.
Thanks
