Custom action

[IrkedCitizen]

No plans on a big boomer, just a moderate boomer.
That's a pretty slick action, price super competitive

I'm ignorant about this little bit-

"All Pierce actions feature the Pierce enhanced Firing-Pin Assembly (FPA). Faster lock time (2.3 milliseconds) and lighter strike (4.3 in/lbs) results in easier bolt lift and reduced disruption when the pin hits the primer."

Is a lighter strike a good thing?

I don't know if it is a good or bad thing. I'm sure they wouldn't mention it if it were bad though? Ryan is very responsive to Private messages on FB so you can always ask him.

I'm not on fb
I'll give them a call after work.

ARC Mausingfield is another option. 83 degree bolt lift and interchangeable bold heads offer flexibility. Not cheap but I really like mine.

Interesting topic that i'm surprised never gets brought up.

Just dry firing my tikkas compared to m700 customs, it is pretty easy to notice that i'm more likely to see the crosshairs move when the tikka firing pin drops and it seems to strike quite a bit harder. I also seemingly need to be on my game with tikkas more to shoot similar groups. The flip side is it's probably not great for reliability but hell if I know where the line should be drawn. Seems reasonable to assume that if the firing pin disturbs the sights on a dry fire it would do the same before the bullet is out of the barrel.

I notice the same comparing my defiance to my tikkas. Almost makes me want to build off another action for another match gun. Tikkas slap pretty hard, If I’m not on it my site picture moves a bit

This is a rabbit hole that comes up about every decade or so in different circles. The short answer is that it is caused by the firing pin bottoming out/not meeting resistance. It has no effect on the shot. You can take a primed, empty case and fire it and not see the reticle jump.

I just tried this. Your right

As in, previously primed and fired, so now dead primer? Don't tell me that ive been chasing a rabbit with my jumps on dry fire.

Yes you have been. Prime a case with no powder or bullet. Fire it. The reticle doesn’t jump.

Good grief...

Ok, riddle me this. When I get a "good" dry fire with no reticle jump, what made the difference? Can you point me to a deeper understanding of whats happening mechanically in the gun vs. mechanically with me?

I think the old snipershide had a thread on it. Long story short, with an empty chamber you are getting a mechanical bounce on the FP when dry firing. With proper body position you don’t get the bounce. With a primed case you don’t get the bounce regardless. You can go down the rabbit hole and drive your self max, or you can use it ad a training aid to correct body position, or you can ignore it.

I’ll take the second option. Thank you, Form.

I just got the Defiance anti gravity in 6.5 PRC. I have it in a chassis with a NX8 scope (Big) and the bolt throw is not an issue. These come standard with a pretty small bolt knob. I could see if a guy was upgrading to bigger knobs, and wearing gloves, this would be closer to an issue, but still doable

Tough to pick a "bad" action nowandays; top products all around.

My current stable has Kelbly's, Defiance, Stiller, good ole' fashioned M70.

Never noticed throw angle etc, grip it and rip it!

Somewhere in the back of the safe there may be a M700 or three...LOL!
