Ruger M77
Until recently, I was using my Browning A-bolt .25/06 at work ('yotes&pigs) but my co-workers were giving me grief about the noise. Nowadays I carry my Ruger M77 .243. One thing I noticed right off was how rough the bolt is on the Ruger. I've given it a good cleaning, but she's still not as smooth as I'd like. Any suggestions on what I can do to smooth up the action? Thanks in advance.

Hi Steve, I am not a riflemexpertmby any means, but there is a video online by iraqveteran8888 where he smooths the boost and receiver of a mosin negant to help it not stick and be smoother. Perhaps the same techniques an be used for the ruger, same problem it may just work. He's a gunsmith and knows his stuff, there's a recent video update on YouTube now.

Cool, I'll have to check it out. From the comments, it appears he did a heck of a job. Thanks.

Repeatedly work the action, it will break in. The inside of Rugers are rough from the investment casting. Or take it to a qualified gunsmith and he can inspect the bolt raceway for any burs or see where it's dragging.

Inspect the bolt for any wear marks and if it's stainless use a black sharpie to blacken the contact areas. After cycling the bolt several times see if you can tell where it is rubbing internally. Use a fine grit aluminum oxide sandpaper to polish the bolt or use a jewelers file or ceramic stone to clean up any sharp edges. Just be very careful not to make another problem for yourself by being too aggressive. If in doubt, take it to a professional!

Sorry for the delay, been rather busy. I've got some AO up to 2000 grit, that shouldn't take enough off to cause problems. Might even try a very soft felt bob or soft cotton wheel (2'') with some emory compund. As long as I keep the speed down, it shouldn't be too aggressive. Thanks for the tips.

I've smoothed up a couple of Ruger M77 bolts (.243 and .30-06) by coating them in a fine polishing compound and cycling them a few hundred times.

my personal preference for this procedure is to remove the action from the stock annd remove all the parts from it and mount it in a padded vice. coat the bolt with very fine valve lapping compound and work the bolt several times and clean very well and then oil the surfaces and see if the action smooths up. repeat as necessary. i like to use a brake cleaner to flush all the compound out, as this is very important.
