I recently purchased some 185gr JHP bullets and decided to load them with 2 different powders to see how they differed. The first powder was W231, the load data called for a COAL of 1.200", I loaded them that way and the case mouth was just below where the ogive starts,,,all is good.
Then I loaded some with Universal and the load data called for a COAL of 1.135", I loaded them to that COAL but it caused the point where the ogive starts to be a good bit below the mouth of the case. I did cycle them through my pistol (not firing) and the whole magazine cycled through with out issue. I do not think these rounds will miss feed or give any problems, it just looks strange to me,,,is it???
I got to thinking if I could make the COAL 1.200"? Would I need to adjust the powder charge? If so what is the formula to make this calculation?
I would think that making the COAL longer than what is specified in the load data would reduce internal pressure,,,but by how much? would I just work up a ladder test to get to the same velocity as the original load?
While I am at it,,,I have some 255gr LSWC bullets that I want to load for my .45 Colt. I want to use Universal powder but I am unable to find load data for that powder with a lead bullet. I have found data for lighter and heavier bullets,,,so,,,how would I go about working up a safe load for the 255gr LSWC???
Please do not just throw load data my way,,,I really want to learn how to do this work.
Thanks
