Never seen it before. I have .327 fed in both sp101 and lcr.
I would not have a problem trying it if I ever ran across it.
I have taught several mature (40s & up) to shoot. I start them with a 22 then move to the sp101 using .32 S&W, step up .32 long,, .32 H&R mag.
Gives most of them a good understanding of the recoil factor. I also then try the lcr to understand what difference the weight of gun makes.
Has worked pretty good in most cases.
Edit to add: Just looked at the website for this ammo. At close to $50 a box for .32s I won't be buying any, Just keep reloading my own.
