MPA PMR Pro Action Break-in

[Packfan]

Hey Guys:

Is there anything special I can do to help break-in my new MPA PMR Pro left hand action?

I understand the action is a Curtis Axiom that is re-branded by MPA. It is finished in raw stainless and the bolt is black nitrided with fluting.

To be honest, the action in my Bergara B-14 HMR is a little smoother. Love the 60 degree throw and the bolt lift is good. I have a old Browning A bolt hunting rifle that is also a 60. I know it will improve with time.

Thanks.

What are you trying to smooth out? Bolt open? Bolt close? Or in and out?

 

[Packfan]

In and out. Open and close are fine. If I really work it hard and fast, it isn't as smooth as I would like.

Shoot it!

 

[Packfan]

Always the best advice!

You could try to LIGHTLY polish the raceways, but the best way is to just use it like cgobeli said. Plus it's funner to shoot than polish.

Clean it
Spray bolt and inside of action with one shot gun lube.
shoot it.

I also like the Hornady One shot spray for cleaning/lube.

Also, I have been using the Swanny's Bolt Action Oil, a little bit on the raceways makes the in/out nice and smooth.

I have some One Shot in my reloading gear and will give it a shot. I hope to get the scope mounted and out to the range before week's end.

I like Gun Butter and Lucas oil on the bolt.
