I wouldn't think you could even get .357's to go off the a gun chambered for 45 Colt...is this....gasp....a shenanigans call?and after 500rds (approx 200 shot shells and 300 .357's)
Lead cannot hurt steel rifling...just don't expect much accuracy.

I will also say I have seen 4 of these at our range...none made it completely through a box of either 45's or 420 shells without the cylinder locking up and having to go back to Taurus.
Is the shot in plastic wadding like many shotshells? The plastic would help protect the rifling.
