Steve I did just such a conversion on my Wolverine a couple of years ago, simple 209 nipple no disc. My sweet lil gun is about 10 years old (was one of the guns still built with an adjustable Timney trigger

) and she has served me flawlessly. Even took a 367" bull in NM in 98 with it (still had #11s with the hot nipple then). I put the 209 kit in it and havent had to change anything but finetune the sight-in. My load is the same it was when I shot 11s. 2 50grn Pyro pellets, 200grn Red Hot bullets and it still prints 1.5" -2" groups at 100yds all day!
Sweet lil gun, but I' m through " washin n waxin" nextyear its a SMOKELESS Savage baby!!!

ps
I use the cheap lil T/C flashcover that velcros over the action and havent had any moisture problem plus it doesnt allow crap to get on the scope!
