Garand barrel recrown/touch up crown against JCG "as issued" rules?

[lemmonhead]

Watch the Garand Collectors Association video with Gus Fisher. He said they would clean up the crown of their NM rifles around every 500 rounds. He said there was a noticeable difference in accuracy when they did this. In the video, he takes an example rifle and uses his crowning tool by hand and works the crown by hand until every land and groove have an new cut edge. I have tried to find the same Severance crowning tool he uses in the video but can't find it.

Sounds like they ought to let the carbon build up, tweak the load, and be good for life. I've yet to see mention of bolt and AR guys doing this.
