No it was not soft at all. Also it's not the only time we've seen it happen.

We've been lucky a few times where we gave the barrel a light finish lap and was able to stop the fouling and the barrels would then hold accuracy with no issues. I'll tell you though we have a 50/50 chance in saving one. It's not a guarantee.

Maybe that one barrel was just bad and super soft. Was that the only time he had ever cleaned a barrel in that manner?
I do understand a smoother surface resulting in more friction.

How many primers have you popped?

By popped, do you mean pierced/blown?

If it is a new action with only 3 range trips and barely getting ignition, I'm betting he comes back with a "zero" answer .

What brand/model of action is this firing pin out of?

It looks like shit.
Somebody molested the hell out of it at some point after manufacturing (. . . .unless Tactical Rifles.net started back up and is making actions now.)

After looking at this altered part, I would question any of the other work to the point I would double check everything else about the barreled action.

This. I would check the headspace (maybe just a bit too much?) and replace that firing pin and the spring.

Complete package SPF.

I'll take this.

Hi guys, I'm looking for some opinions on this firing pin. Without going into too much detail I just want to know if you think that the obvious asymmetry (zoom in) is something that could cause issues with light strikes. I feel like it's dragging and binding on the bolt body. I'm getting way too many clicks and with 3 different primers.

The color variance makes me think it has been heated. Like really hot for some reason.

It was so hot that they actually experienced some of the material being ablated away from the torch blast (see inside yellow box above). Even more importantly, I would bet money that the composition of the remaining material in that area is altered. I would guess it is now brittle and prone to a stress crack/failure.

It also looks like it has been unevenly ground or aggressively wire brushed. I say unevenly because it appears to have some really distorted geometry to the point I would predict a failure somewhere down the road.

All that being said, the tip of the pin looks to be in good shape.

Even though the firing pin looks like it was made from scratch in some cave in Pakistan, that may not be the source of your ignition problem.

Come on guys! There’s got to be one of you close enough to drive that want to test your skills in the buttes of Colorado!!!

Thanks for "breaking trail" on this appliance.

So, what am I doing right that this barrel has survived 10-12 cleanings with Thorroclean? Not only survived, but still shooting bug holes. That is what I'd like to identify and possibly separate from the one & done toast jobs.

That's the million dollar question I cannot answer.

Why does one guy not have a problem but the next guy does?

Are you using a bronze brush or a nylon brush?



A ammo maker called me last year some time.... and his exact words were...."Hey we are trying to cut down on scrubbing time (cleaning)." What do you think about using a stainless steel brush and even an abrasive. I said.... Don't do it. Your asking for it! Then I said... on 2nd thought... knock yourself out. You will be buying double the amount of barrels!

Another bullet maker told me.. if they feel the need to clean a barrel with an abrasive (think they use JB if I recall correctly) only one guy... again only one guy is allowed to clean the barrel with the compound. All the other guys in the ballistic lab are not allowed to touch the stuff.

Two form 4’s certified Saturday 3/29. Approved Tuesday 4/1. Individual.

I copper-hammer tested one of mine. All I did was get a sore arm and bend the base.
