45ACP to 10mm dimension comparison (length wise) - XDTalk Forums - Your HS2000/SA-XD Information Source!

rbyrd · 03-13-2006, 08:46 AM

I have a question. I know of the excellent ballistics and how impressive the 10mm round is, but I have never had the pleasure of shooting one nor have I ever compared one side by side to a 45ACP round. I have seen quite a few requests for 10mm conversions for the XD45ACP so here are the questions I have.

Dimension wise, I know the diameter is larger for the 45ACP compared to the 10mm (.451" to .40"), but what is the difference in the length of the 2 bullets?

O.A.L. is the same. Case length is longer on the 10mm.

10mm is 1.260" Max OAL (Over All Length)

45acp is 1.275" Max OAL

10mm SAAMI max pressure is 37,500 PSI

45acp max pressure is 21,000 psi standard or 23,000 psi +p spec

Well, they're ALMOST the same o.a.l.

I load my 10s and .45ACPs to the same o.a.l.
