First, I'm not a gunsmith, don't have the tools / calipers / reamers.
That said, has anyone noticed that the diameter of the same caliber bullets varies? Here's what I notice: I insert various bullets into the chamber throats of my Ruger Redhawk 41 mag.
All the Remington 210 JSP bullets enter all the throats easily. All the Winchester Platinum and Silver Tips enter all the throats easily. *Some* Spear Gold dot 210's fit into all of the throats, and some of these bullets are very tight on a few of the throats.
None of the Corbon 250 gr. hardcasts pass through the chamber throats.
How should I read this situation? Are some of the bullets out of spec or is the Ruger out of spec?
Thanks
