I have not found any loading data for the new 30-30 140 gr. GMX bullet for use in a 308 marlin express rifle. I know it is a 30-30 type bullet. But I use the 160 FTX 30-30 bullet in my 308 marlin with good success, before the FTX 308 Hornady bullet hit the market for the 308 Marlin Express.

Thanks for any help.

I haven't found any data for this 30-30 bullet in a 30-30. It amazes me how Hornady can announe a new bullet 8 months before its ready and still start shipping without any data.
I have a box but I'm not sure where to start. I think maybe I will start with data for the Barnes 150 FP.

I'd start by using data for the next-heaviest bullet you have data for, and work up from there. :)
