I bought a passel of those W/W "8mm Special" 170 gr. ctgs. from a sporting goods store/gunshop (still there in 2010!) in Lewiston ID when I lived out there in the 1970s. They had picked them up "second hand" someplace and sold me 8 boxes cheap.
I had a 1917 Erfurt-made Kar98 "sporter" from a garage sale (Thanx, Bubba, I think!). Killed a meat deer every year with that until I could afford better. We chronied the shells and from that carbine they had almost identical ballistics to the .32 Win. Spl. Very soft, any way you figure it. Probably fine in an '88 of any bore.
