I give up....why can't you? Seems plausible.......but practical, not so much. I've hunted deer with both a .357 revolver and a .357 lever. Both using a 158gr bullet over the top of a full charge of W296/H110. Killed deer with both. Shots were under 35 yards tho and waited for a perfect shot. Deer still went a good 40 yards before they dropped.
Again, referencing my experience with full blown .357, I have to say, I think you're embellishing the terminal performance of the XTP from a .38 special, even if it is indeed +p. Out of my carbines with .357, I prefer the XTP-FP, because the standard XTPs are a tad fragile when pushed to carbine velocities. Mine were a titch over 1650fps. The XTP-FP gives better odds of a pass thru than the standard XTPs and I've found that having two holes for blood to leak out onto the ground is better than one, when using a .357. Again........I'm using legitimate .357 loads.
While I like me some IMR4227 in .44 mag carbines, in .357 I could not get more than a tad over 1500 fps outta my 20" model 92. I have doubts if one could get 1400 using a legitimate .38 special load. Problem is, it's hard to get enough of 4227 in a .38 case to get those velocities with a jacketed bullet....maybe with cast lead.
Now this I believe. Save it for the woodchucks.
