Minor/Major Power Factor & Accuracy?


Recommended Posts

My caliber conversion for .45 ACP will be here in a few days (yea!). Not having loaded .45 ACP previously I would appreciate advice from the reloading Sages on here...

 

I understand each gun will be different however I'm wondering what a good rule of thumb over the minimum would be knowing just loading the the very minimum PF likely won't be the most accurate?

 

125 minimum to 130?

170 minimum to 175?

 

Thank you in advance for your thoughts!

I've posted extensively about that. Do a search on Reloading to Meet Power Factor or similar and articles should pop up. 

 

BLUF: add 2 to 3 times your measured STD to the velocity needed to make PF for your bullet weight.  Adjust as needed for accuracy/preference but don't go below 2xSTD.
