Brushed Firing Pin

Yep, been there done that. One model 12FV in 223 I bought when Savage was dumping stock had a very poor fit to the bolt face. It would blank primers of factory ammo and very mild hand loads. I measured the pin to hole fit and it had like .004 clearance. I was able to order firing pins from Savage back then, now you have to have a FFL, and cherry picked one of the 6 I bought. That fixed the problem. Later I did have a couple of my Savage Bolt heads BUSHED. What a difference!
 
Google the word "bushing". You are not "brushing" the bolt your are normaly turning the firing pin down in size and then adding a bushing to the bolt body where the firing pin protudes.

Multiple reasons, one is to reduce the diamter of the firing pin, reduce the clearance between the firing pin and the hole in the bolt and last some bolt allow the pin to travel un-guided as in not supported for it's full length of travel through the bolt body before it hits the primer this fixes that as well!

I am only 52 but it seems like what what once common knowledge decades ago has been total lost on the masses. The internet has made things worse not better!

You want to know why? Guys like but not limited to likes of "Name Redacted" national and world champion and member of this sight and other competitors profit off of secrets and lies and half truths. The real truth is only shared within a tight knit circle of insiders.

It is sad but as you climb to the top things get cut throat and very catty like pre-teen school girls in the bathroom! PEople want to win at all cost and often spend insane amounts of money to attempt to gain a competitive edge. This means they burn th bridge behind them for 90% that might try to follow them!

Same thing happens when you mention sleeving a bolt or Borden bumps or blue printing a bolt.
 
Nothing against bushing a bolt.

If one thinks looking at fired primers is a way to judge pressure, I don’t see it being repeatable.
Pretty easy now days to watch your chrono, speed = pressure, hard to get around it.

As far as successful competition shooters are concerned, my experiences have been very different from what you claim. To a man they have all been gracious and helpful. The NBRSA has a mentor program. Individuals have offered the use of equipment so that new shooters can gain the experience of shooting a match virtually without any equipment investment. In some cases match directors have waived match fees for first time shooters. If you look on You Tube, Jack Neary and Bart Sauter have videos that provide a ton of useful information. Several top shooters have published bucks that are full of tips. Generally I do not mind people posting under screen names, but when things get strongly negative, it makes me think that they are "keyboard brave" (made less cautious by their anonymity).
