D.I.Y. Bolt lapping for Accuracy

[@tomjoseph1444]

I have been doing it just like you show for 40+ years. It amazes me how people think they need to have all this specialty stuff when everyday items work just fine.

[@kurtnulf3362]

You need to use a shell case in the weapon to but pressure on the bolt face to properly lap that bolt

[@screwyu1329]

Flushing out the action with brake clean works very well and is easier to use.

Did this with my rem 700 rem mag really improved accuracy easy to do and did improve the gun now 1 hole at 100yards with 162g a max home loads

Nice video, simple to the point.

[@markchester7584]

Quality manufacturers have tested their products and given sub moa guarantees or better. What are people buying that requires this?

[@jonpaulison2283]

Thanks for the video

A Go-Gauge would be ideal. However, having a No-Go gauge handy would guarantee that you would not have overdone the lapping. If so, then head spacing must be done as well.

Thanks for this excellent explanation and it presents ideas for additional accuracy. I would imagine this is especially true for well broken-in rifles, magnum (hard-hitting) rifles, and for entry level rifles as well. I noticed that you were pointing to the rear lugs. Do you do this to those lugs and the front lugs, or just the rear lugs? On my Savage axis receiver, the locking (seating) lugs are the front ones?

Thanks

what about changing a headspace by doing this? Doesnt it present a bigger danger? Anyhow, how much in accuracy did you gain afterwards?

[@grouptherapy5983]

It would take some effort to lap the lugs so far that headspace is affected to the point that it becomes dangerous. If you use aquarium gravel to lap em, then maybe itll affect your HS. :) Lapping anymore isn't much more than a means to verify if you have lug contact on both sides.

[@partisan5695]

@@grouptherapy5983 Ok. Nonetheless, I would refrain myself from going that far. So can you report that doing this has actually improved the accuracy of your rifle? Tnx

nope.... kzbin.info/www/bejne/qmqzhXujg9CDnqc

[@sgtstedanko7186]

it can change the headspace. besides if the bolt is so far off that it needs to be lapped then that's an issue with the manufacture of the part. in my experience it's more about the accuracy and consistency with which you handload your ammunition. paying closer attention to sorting brass by weight and brand, turning case necks, trickle charging powder, using the right bullet for your twist rate, and seating/crimping with good concentricity.

@@sgtstedanko7186 it's not going to change headspace, this is been tested a dozen times. And you can take any factory gun off the shelf and do a bolt contact test on it pretty simply and you'll see 99% will have a contact issue.
