Among those who've tried it, Magtech brand ammunition is often reported to have split cases.

Magtech does load one of the few JHP loadings for the .32 SW Long. Some countries, such as India, have handgun laws that make the .32 SW Long the most potent of the calibers that can be legally owned. (They turn out crude Webley copies for the local market in India, well not really copies, since they bought the original machinery...) In India the Magtech offerings are regarded as the fancy imported stuff. That tells you a little something about the quality of domestic sporting ammunition there.

Anyway, the official firearms safety rule is to fire any firearm only with the ammunition for which it designed and stamped. I also suggest that you might have to delete the part in the first post that was copyrighted?

The Nagants were popular for a long time in Russia. Supposedly you could fire them out the slits in a tank without the worry of it jamming, unlike a Toke. I remember a filmed interview with an old Cossack officer who claimed that Nagants were wonderful because one could repair them with a hammer...
