I'm told that my 317 Smith shoots poorly with the new lead free ammo because I haven't removed the lead left by the lead .22 Long Rifle ammo I've shot out of it. It's been a very long time since I've even paid attention to this issue. I seem to recall that Hoppe's No.9 did a good job removing leading. Is that still true with the new formula ? I have a new bottle of that stuff. If not, what would you recommend ? E
