I'm getting ready to buy some 400gr Crusher coated bullets in 500 S&W from MBC. I can't seem to find any load information on these. I have the Lyman Cast Bullet Handbook 4th edition, they show a 400gr bullet but it isn't from MBC. Just wondering if anyone here has any load info for this bullet.

If the profiles for the Crusher and the bullet in the published load are similar, I would not be afraid to use the published start loads to begin with and go from there. Kinda how it is with so many of the newer Boutique style bullets out there. Very few have actual tested and published loads for them.

More of how much bearing surface the bullet itself has. If both are RN/RNFPs, odds are you are good to go.

The overall length, bearing surface, and where the crimp groove is. If the weight is the same and the crimp groove is in the same spot then the pressure will be about the same. This is one of the reasons why you work up your load. Because no two firearms have the exact same ballistics picture, small differences in components are "close enough" to start a load work up. Lead/plated use one set of data and jacketed use another data type. If in doubt of data for a unknown bullet use the data from the next heavier bullet as the pressure and VEL will be less, and work up----is something all reloaders should know as well. OP as you gain more experience there will come a time when a good educated guess extrapolated from current data will yield a safe starting point with most any bullet. For now sticking to the published data (within reason) is a good bet as you gain experience.

Welcome to the forum.
It's impossible to test data for every bullet manufactured everywhere. This is why published load data is given in a range of starting load and max load. When one charge is given it's usually the max charge. Reduce it by 10% to find the starting charge. Use data for bullets of the same composition and profile, start at the low end and work up. When you find an accurate load stop and you're done. (below the max of course) Be safe and have fun.
