Seems I've stumbled into a discussion of my favorite subject--200 grain .38 loads!
Landric, I need to touch base with you on how you're loading to obtain those velocities. Those will hit with authority! Maybe I'll dust off my Forster hollow-pointer after all & use it on some of my Mt. Baldy 200g LSWC-Ks. Also, I need to try that 30-1 mix to cast softer bullets more likely to expand, then drill the noses of some of my 358430s. I think my eventual SD/HD selection will be SAECO #351, a 200g FNPB, cast soft, hollow-pointed. Best combo of weight, shape, sotness, and expansion. Thoughts?
When I recently tested a few factory W-W 200g loads provided by another shooter, they chrono'ed 605fps from my 2" snubbie. One round was 681fps from a 4" revolver. A round from the snubbie penetrated 5 gallon milk jugs at 10', then veered off to miss jug #6, dent a 2x12, and carom away.
When I tested 200g LSWC-K at 718fps from 2" bbl., it bored straight thru 6 jugs, drove into the 2x12 up to the driving band--knocking down the board--then fell out. As someone noted, penetration in different media can be tricky; I suspect that the 200g lead .38 is good on soft stuff, not hard stuff.
My current defense load for standard pressure .38s and snubbies is the LSWC-K load at 750fps from a 4" bbl. I'll see what hollowpointing in soft lead will do, as soon as I get my hands on some pure lead. (I have only WW at this time.)
As another poster mentioned, the Brits put stock in the wounding properties of soft lead bullets, both in .455 and the subsequent .380/200. More modern studies often indicate the same thing. Notably, Buffalo Bore touts the softness of some of its defense loads. . .and I imagine it's because he buys some of the same logic.
