lapping compound

[tonyb]

What have you found that works best for lapping in bolt lugs. The last container I had lost its label, and I have no clue what grit it was.

Thanks,

Tony.

600 works for me....

I don't lap lugs as I see no benefit.

I use 500 grit silicon carbide paste from Brownell's.

If you are getting single lug engagement you need to true them in a lathe first. Being careful to not take your gun out of primary extraction. If required be prepared to move your bolt handle forward and retime it. Lapping an untrued bolt only makes the problem worse.
Just my opinion.

Not looking to "even up" the lugs per se, as I know to recut them if they are out. I simply like to give them a light lapping to take any minute galling or scratches out. It may only be for cosmetic reasons at best. I should have explained myself better.

tonyb,
I've posted this before. If you have a factory receiver, say like a Remington, your bolt has enough play that when the bolt is cocked the rear of the receiver is pushed up by the cocking piece when it rides over the sear. That in turn unloads the upper lug.
You see, you wasted time lapping. If you sleeved your bolt or bought a Kiff bolt that was fitted to your receiver, it will be closer to what most people lap a bolt for.

If you are loading with the bullet seated into the lands, or you are not full length sizing, and the rear of the cartridge is against the boltface firmly, does the top lug still lose contact?

Take it to my gunsmith!

 

[butchlambert]

Yes sir.

Take it to my gunsmith!

What will he do to it that myself and a couple hundred gunsmiths do?

nobody answered my last question... I know how to cut bolt lugs, I know how to cut integral lugs, I simply asked what was the most popular lapping compound grit size, if you don't use it, don't respond....

Thanks for those of you who are courteous enough to answer a simple question! (this is you Preacher, TRECustom, and Rustystud)

On to more important things....

Sorry, didn't understand it was for cosmetics. I would continue on through Jewel's Rouge. When you show your Buds your bolt lugs they will shine like a diamond in a goat's azz.http://forum.accurateshooter.com/Smileys/default/grin.gif

I came in too late and missed all of the pissin' match...rats. Grit wise, 600 will do you fine. You will find a very slow feed rate on your lathe, lapping becomes bling. Gun guys love bling. For a super shiny rear lug on the bolt, jewelers rouge (sp) works well.
