Gents:
If someone can l email me and let me know how to post photos on this site, I will be pleased to show you detailed photos of my Barnes Banded Solids I shot through my .600 Wilkes. The rifling cut the bands but did not contact the body of the bullet. I think this is the answer to OSR--bands and a bullet .002 undersize. I saw a mild case of OSR at SCI Reno and seeing made a believer out of me.
Cheers, all.
