Bigbully

I used 2.5 inch lag bolts in the front, and nut/bolt combo with lock washer in the back. Seems to be working just fine.

New to reloading. After looking through numerous manuals and on line load data, I cant find any concrete answers. Example: The Sierra manual shows the load data for my bullet weight, cal, and powder (180gr, .40, WST). However that data is for a JHP bullet. I intend to load the Hornady 180gr FMJ-FP, do I have to adjust the load at all? Is bullet weight the only concern, and the shape is not a factor? Thanks in advance! Tom
