Yes, they're all Woodleighs of course.
Geoff MacDonald specifically designed the bonded-core Woodleigh 'Weldcore' RNSN bullets to perfectly duplicate the Kynoch pattern softs and solids for ease of regulation in British double rifles. 'Nuff said. They just WORK!

I'll leave it up to others to toss around all that stuff about homogenous bullets in DRs (with or without bands!).
