First let me say, I’m not trying to take business away from the guys who are busting their ass making a living as gunsmiths; I’m not looking for any trade secrets; I have no special tools.

I have a Mark X Whitworth, 375 H&H that I bought at a general store for what I thought would be a “one time†use (got drawn for a bison hunt) but I have fallen in love with the gun & caliber.

It is plenty accurate with anything I load, wondering if there is anything I can do at home to make the action smother.

Is polishing the bolt something I can do or should I take it to a gunsmith?

Work the bolt a couple thousand times. Speed it up with a little polishing compound. I sit and do mine watching TV

Thanks Ramrod, is there no end to your knowledge, keep schooling us pups

what grit would you recommend for the polishing compound

Oh there is definitely an end. I just try and remember most of my own screw ups and try not to repeat them. YOu are not paying attention if you don't see me asking for advice.

I use simple valve lapping compound picked up from the auto parts store. I'm not sure of the grit. I also have Wheelers 600grit. I have not used it much.

Remember a little goes a VERY long way if you get it on the back of the lugs. Along the slide rails and the cocking piece will smooth it up quickly.

i use "mother's nano polish" ... you can't feel the grit...

Anything else I should do beyond polishing the action?

Adjust the trigger and safety. I glass bed mine.

You probably can't do this at home but the addition of a three position safety is a real positive addition to the MarkX....I heartily recommend it.

The bases were not a very close fit on top of my Mark X, so I epoxy bedded them to match the receiver. Used my Dremel to cut some grooves in the bottom of each mount to hold the epoxy.

I would strongly recommend this on such a heavy kicker as yours (mine's only a 243). Your scope mounts will stay tight longer and can't rock or otherwise shift around.
