Load data for 44 mag, 300 gn. Lead flat point

[ke6igz]

I am looking for load data for 44 mag, 300 gn. hard cast lead flat points. I see a lot of data for jacketed bullets. I have googled around but I don't want to try someones load from a forum post.

I have Unique, AA#5, Bullseye and International Clays powder on the shelf. I also have H110 but I don't think thats suitable for lead bullets. I use that for hot loads using jacketed bullets.

Your 300's will probably run about 1100fps if they're hard cast you'll be alright. If not tone it down some. The slow powders are perfect, h110 ,296 2400ect. With jacketed bullets aren't as greasy & pressures will show up sooner. I reduce my load 1/2 gr in that case.
