Nothing wrong with #34 primers. I actually prefer them. They are a magnum primer, and their intended application is 7.62 NATO, which are loaded with WC846 (Hodgdon BLC2). Ball powders, like that, ignite more consistently with the magnum primer flash.
Standard primers, like #200, in your intended purpose (bolt gun stick powder loads), will ignite just fine with them. There is nothing wrong with using #34's for bolt gun loads, but it is possible they may develop higher pressures, and therefore, you need to re-work-up your load, starting lower than max.
