At a gun show a week ago and was lucky enough to come across a few boxes of .45cal 300gr FNPB bullets at a real cheap price. I was thinking of using them in my .460. Now, the powder I have to work with is AA5744. No listing in any book beyond 270gr. What do you guys think? Go with 270gr data but reduce by 10%?

There is data for a 325 gr cast bullet.

Yes I did see this on the Accurate website. Normally I load for bullets that are listed but this one isn’t. If it’s feasible to use the 300gr (which actually weigh 307gr) following Accurates data, how much should be reduced to start?

Dumb question - What diameter are they?

If it were me. You need to decide for yourself if this is safe. I would start 10% below starting charge for same weight jacketed bullet.
