PaddyDaddyO,
FYI, "VPT"= Valtion Patruunatehdas, Lapua.
Lapua makes good ammo. Your translation of the ammo box is probably pretty accurate, as I can't read Finnish either
I can tell you with pretty good certainity that the last part of the label:
N:O 6 Sinoxid is going to be the type of primer. Sinoxid is a primer type developed by Dynamit Nobel of Germany. It's non-corrosive and mercury free.
I wouldn't worry about the fact that the Finnish ammo is steel jacketed. Steel bullet jackets are made with a mild steel alloy, not pure, hard steel. You would have to literally shoot tens of thousands of rounds to wear out the rifling of your pistol. I think this concern is more myth than truth. (Where's the "Mythbusters" when you need them?).
Regarding Winchester's WinClean 9mm ammo, Winchester's 2005 catalog shows the following stats:
WinClean 115BEB = 1190 fps MV.
WinClean 124BEB = 1130 fps MV.
WinClean 147BEB = 990 fps MV.
These velociites are in the same ballpark as the equivalent WWB FMJ loads. The WWB 115JHP load has a MV of 1225 fps.
Hope this helps ya.
Good Luck. ^c
