Anybody have 357GWM load data to share?

[komishe]

I'm trying to help my friend get some data for his LAR Grizzly and 357GizzlyWinMag data is pretty scarce on the enterweb.

He has 1 load for 2400 powder that came with the gun but I couldn't scour any up locally.
I have 140 and 158 grain bullets for him and h110,w296 and some blue dot. Not really a magnum handgun loader, just had these around for 300blk and 5.7x28
I do have some other powders around so any recipe is better than the one we have.

Thanks

What is your max bullet weight for 5.7x28? Having trouble like everyone else in finding components for my 57. But I have plenty 50 and 55 grain .224 bullets but no data on reloading over a 40 grain.
