Bore Lapping

Post by Vafrum » 25 Mar 2010, 16:33

*Not running past male hogs in a race.

I wonder if anyone has spent any time and energy looking into bore lapping. There are a few products out there. All claim to smooth out the bore or chamber.
Is this nonsense? Has anyone tried this?

If so please support by listing your findings.

Thanks,
JBL

Can you tell what products in particular?
I could guide you through it, depending on what is available to you.

Ok, I'm looking at a "Wheeler" bore lapping kit. In Midway's most recent catalogue. Costs $32.99.

Tubb makes lapping ammo, but not in 5.7x28.

Looks like Tapatalk is bypassing the server config to not allow attachments. Please do NOT try to upload things to the server. Please use something like photobucket or imageshack.

The range of the 5.7 pistol is amazing considering how short the barrel is.

I have used the Tubbs final finish bullets in 4 different rifles with great success,the really made a improvent in accuracy. I dont think you could load the 77gr bullets in the 5.7,I dought the results in 4.5" barrel would be worth the effort.

Can you put that into MOA terms?

my savage MK 2 shoots 3/8" ata 50yds with fedral gold medal match, and just as well with remington 36gr subsonic. ( a squirrels worst nightmare) my 300win was 1-1.5moa and now 3/4 MOA with same load...... you can feel the diff. when you push a jag through the bore. I think its worth while. proper barrel break in and time would do the same but this is faster and cheaper than several hundred rounds of centerfire ammo. :D

No it just smooth the machining marks on top of your rifling lands.
