Load Data, using FMJ's instead of JHP's

[twolf]

Ok,
Maybe I am missing something here but I have a question.

If you find a load for a 115gr JHP round, could you not also load a 115gr FMJ round using the same brand of powder, primer and grain load of powder?

I mean I know you do not want to go with a heavier load becuase it creates extra pressure and could destroy your weapon but if one uses the same grain, it shouldn't matter whether one is a hollow point and the other is a full metal jacket.

What say you all?

I'd figure that they could be loaded with the same data, and I'd look for data in all my sources. Then after I found a load "range" I'd go back to the light loads and work up. That way even though we're "probably right" you'll know for sure and be safe about it.

Really bad form to change bullets based soley on weight.
There a are other variables involved that can raise pressures.

1. Amount of bearing surface
2. Jacket thickness/hardness
3. Core hardness

You would need to rework the load.

I would not switch bullets without droppind down the powder charge and working up again, just seems to be the safe way to do things.

OAL would definitely be longer for FMJ's too...
