Need recipe For Missouri Cast 245 Gr. In 300 Blackout

[UtopiaTexasG19]

I've ordered some of the bullets pictured below from Missouri Cast Bullets to try in my 300 Blackout but I have yet to find a powder range in anything this heavy. I have been using H110 for loads up to 150 gr. so far with great success. Since Missouri Cast Bullets is selling this bullet I assume someone out there has a recipe but for the likes of me I cannot find one. Can anyone help please? These are .309 diameter.

No need for additional help. I started re-loading last night and tested this morning. Found the perfect combination for my particular gun with the cast 245 grain 300 Blackout round with correct OAL at subsonic speeds where everything cycled just great. Pictured below a .223 reload at 65 grains next to the 245 grain Blackout loads. A happy camper here! :)

So what was your perfect combination?

Yes please share some info , I'm looking at building a 300 AR but am not sure. I wish to cast and load my own 300BO but so far I've stuck to handgun <1000 ft per sec loads. I want to minimize leading and try not to use gas checks. Has anyone successfully cast and loaded non gas checked 300BO with frequency and little-no leading?

I have loaded 230gr and 245gr with no gaschecks and they work with no leading. My current favorite load however is a 155gr with a gas check.
