Hello,

I'm fairly new to squeezing accuracy out of bolt actions and I have a few questions regarding the bolt face. I assume the primary accuracy-affecting factor is whether the bolt head is square so as to hold the cartridge straight in the chamber before and during ignition. I'm also wondering:
1. How clean do you need to keep them? When dirty, do they affect accuracy? (reference photo below)
2. Why is the PTG bolt head better than the stock one? Is it worth the $50 bucks?

Here's the bolt face on my 308 prior to cleaning. Other than giving it a good scrub and trying to get that carbon ring off, is there anything in particular I need to pay attention to?



As always, thanks for your input!
