OK, seems like what I'm hearing is that if I switch to pc bullets -

1- bullet sizing isn't as critical to bore deposits as using traditional cast/lubed, BUT if you want the best accuracy, then having the right sizing is still important.

2 - bullet hardness is still a factor in getting the best performance from pc bullets, and may need to be changed based on the application.

3 - Based on information here, it would indicate that if proper care is taken to selecting all components, including bullet sizing and hardness, then great accuracy approaching jacketed rounds can be obtained.

4 - If the above is followed, bore cleanup is easy and there's no indication of excessive bore wear.

5 - they come in pretty colours.

This still sounds better than what the typical plated bullet can do today(in terms of accuracy at least), at least AFAIC. So it comes down to production time and cost. How does this process compare to cast lead/lubed bullets? Is this something a private caster can do or does it require special equipment to process the coating?
