Ok have a pretty simple question. I completely understand the difference between a LRN and a FMJ-RN.

My question is when looking at manuals if they say LRN and there is no FMJ-RN in the manual, can you use the data for the LRN for the FMJ-RN, and assume the same powder charges and OAL? Assume everything is the same (ie powder to be used, weight of bullet).

I will be loading 9mm 115gr FMJ-RN. I ordered the Winchester, mainly because that's what I'm used to shooting off the shelf.
