Load data for .45 colt 255gr FP - The Firearms Forum

midlifevette · 01-10-2011, 04:40 PM

I can't seem to find load data for a 255gr FP plated bullet for my .45 colt. There's plenty of 250gr and 260gr data but can't find 255gr. Is there a safe way to extrapolate between the two? I have Hodgdon Titegroup powder. Ken

Ken. I get in trouble from some other forum members every time I suggest going out side of the loading manuals so today is not going to be any different. Pick a load you like for either one, the 250 or the 260 and load it with you 255 and go enjoy it. All of the loading manuals of today are so conservative that you have plenty of margin. Another thing think for a moment what is the difference in percentage between 5 grains and 250 grains is just 2% which is not much.

Ill agree with dobber, I would err on the safe side and use the data for the 260 gr bullet. Make sure its lead data, the plated bullets work best with lead data in my experience...

(yes I am aware that berrys recommends low-mid range jacketed data with their bullets)

I found 255gr load data in the Lyman's manual but it's for "alloy" bullets. How much difference should there be between "alloy" and "plated" bullet charges? Ken

alloy is cast lead, that data will work perfectly... Plated bullets are merely swaged lead cores with a 'candy' shell on them... the plating is there to prevent leading
