45 ACP COL

I've been reloading 45's for a while now for my Taurus PT145. I just bought a new XD-45 and pulled the barrel out to check the cartridge overall length in it. All my reloads and WWB factory ammo have the bullets contacting the rifling. Won't this cause excess pressure? I can reseat the bullets on my relaods deeper, but it surprised me the the factory WWB was too long. Any opinions?

My reloads are an overall length of 1.250" with a Hornady 230 gr. FMJ-RN. The WWB has an overall length of 1.265"

Hello IMHO in the 1911 type pistols if you drop a loaded cartridge in the clean chamber of a barrel it should under it's own weight drop so that the head of the case is flush or slightly deeper to the end of the hood of the barrel . It sounds like you are a step up on most pistol owners in checking out your new pistol and if the XD-45 has a normal 1911 type barrel then it seems like you have a slightly short chamber I don't think the pressure will be raised to an unsafe point but if this is your CARRY GUN then I would only carry it with the brand of ammo that fits your chamber.

Visually inspect fired primers for signs of being over pressure. Compare the radius of the primer cup to an unfired round. Look for excessive flattening and stop immediately if you see a primer that has been pierced by the firing pin.

The bullet may not be touching the rifling, sometimes the extractor
claw holds back the catridge.
