I know full length resizing of belted cases ruins the case after one or two reloadings. my brothers #1 Ruger 375 did anyway. they would seperate about 1/3rd of the way past the belt. Neck sizing cured the problem, I wonder if this could be related since they both headspace at the rear of the case.

Could. Shoulder locations on belted magnums are all over the place since headspace is measured off the belt. The best way to size belted magnums is with the cartridge headspace gage found in this article:

I think 30-30 Winchester is more standardized.
