44 Magnum/Special Loading Data Question
I'm going to be loading Hornaday 200gr HP/XTP .430 bullets using Hodgdon Universal Powder. The online Hodgdon 44 Magnum chart calls for either 10 or 11.1 grains, but only lists a .429 JHP 200 gr bullet and not a .430. The same thing applies (but in different grain numbers, of course) for the 44 Special chart loads. They only list the 200gr in a .429, and not a .430.
Does this matter? Can I still go with the grain numbers they're listing?
I don't want to use the wrong amount since I'm using .430, not .429.
Thanks. [:D]

My Hornaday book shows .430 across the board Mag/Spcl.? 0 -
You can ignore it - assuming you use normal workup methods, of course.
In practice, you might find bullets in a given box that range from .4285 to .4305 anyway, no matter what the label says.0 -
That's what I say- Now in BP cartridges and I am sure Rocky will agree
You have to watch the .45 cals. some are .454 and .458.0 -
I went to the Hodgdon website, and I think I see what you are talking about. In the 200gr jacketed bullet using Hodgdon Universal powder, the bullet Hodgdon uses for load data is a 200gr Nosler JHP bullet in .429 diameter. If you are using a 200gr Hornady XTP which is .430, this is why there is a difference in the diamter.
Agree with Rocky Rabb, since you will need to work the load up anyway this shouldn't be much of an issue.0 -
76k20, FrancF & Rocky- Thank You.
Now I can move forward and not worry about blowing my revolver to pieces, literally.0 -
As we always preach, "start 10% under the listed loads and work up, looking for signs of excessive pressure."
Be safe and have fun!0 -
