I figured Ill post this in the revolver forum since these bullets are kinda revolver centric but if mods want to move it I understand.
After loading up a bunch of 125gr XTPs I recently found in stock I noticed how similarly they are to my 140gr bullets. I weighed a loaded comp 2 of each and they weighed the same...
Hmmm.... Powder is 9gr unique vs 9.1gr be-86.
Im going to take some apart tomorrow.
It should be pretty easy to tell by the length under the crimp... Hopefully
