I've been reloading about a year, but am still figuring this out.

I need some advice.

I want to load some Hi-tek coated .44 180gr LRNFP up to moderate magnum velocities to mirror my defensive load. Because they are coated, I'm not worried about leading. The issue is you're supposed to use lead data with coated bullets and most modern reloading guides cut off reloading data for lead bullets at around 1100 fps, I'm assuming because they are worried about leading at higher velocities.

So, for example, my Hornady 9th says:

180gr JHP XTP - max loading is 11.8gr Universal @ 1400fps
180gr LSWC Cowboy - max is 8.7gr Universal @ 1100 fps

My notion is to use 9.5gr of Universal under a hi-tek coated 180gr LRNFP to approximate a 10gr load under a 180gr JHP XTP. I know the difference between lead and jacketed loads isn't huge, but the fact that I'm starting with a load 0.8gr above 'max' makes me nervous. I figure I'll look for leading to be sure the coating works as advertised, but otherwise I should be ok.

Does this make sense?

If I was so inclined, could I take the coated bullet up to 11.8gr but I'd just have to watch closely for leading?
