[QUOTE="ejg, post: 2346674, member: 12381"] I do not buy into the gritty bullets. I have however done a lot of precision lapping in general Engineering as well as advanced ceramics. Most of my factory barrels I hand polish/lapp. I use Peek a very fine (aluminiumoxide I presume) paste or liquid. Wrap cloth or paper very tight around a brush, add peek and give a few strokes before repeating. Stop about 2" before the muzzle. On the last stroke it goes out the muzzle. Once the barrel feels smooth, clean and shoot it. My new Rem 300wm long range was spewing around 2-3" at 200yds and after the treatment my first group was well under 1/2" at 105m. I have been doing this since about 15 years now on new rifles or those that seem to go off badly for whatever reason, if that doesn't work the barrel goes in the bin. The rem 300, we don't have any ranges near us so I mostly check/zero off the hood of the Landy.

She was also polished/lapped in the same manner. [img]https://i.imgur.com/96HVFcp.jpg[/img] edi [/QUOTE]
