    Soldered a .020" shim to the trigger of my 340 Savage to cut down on sear engagement using this method, worked great!. First tinned a .020 feeler gage and the face of the trigger hook. With tin snips cut off a thin strip of .020 gauge and placed it on the trigger. Heated the two together and voila success. Went from a 4+ lb creepy trigger to a nice 2.5 lb trigger. The steel wool trick with Nokorode worked great. The downside to this trigger mod is that it negates the safety as the trigger does not go back far enough to engage it. This is only a range toy so the lack of a safety is not a problem for me. The upside is when I get ready to sell this gun some heat removes the shim and it's back to factory specs. BTW I found small amounts of 95/5 tin/silver solder at Home Depot reasonably priced. Thanks Goodsteel for the knowledge.

    Fair warning, Home depot lead free solder is 95/5 tin/antimony, no silver. If labeled silver bearing, then the msds says (i think, bad memory) between .1-.5% silver. Come to think of it, i think the msds said 3-5% antimony too.

    if you want an even better price for what appears to be the same stuff, Harbor Freight sells lead free solder too, and cheap.

    WR--The tube I bought said Fine electrical rosin core solder and stated contents as 96% tin and 4% silver. It was .5 oz and a couple bucks as I remember. As fas as what I was using it for it wouldn't matter if it was 50/50 lead/tin.

    Melt temp is 460 deg and tensile strength is 14000 psi

    The main thing is that it has the tin content in it. Seems the tin is absolutely essential to getting it to wet to steel. I have lots of 63/37 solder here (63% tin) and you can't get that stuff to stick to steel to save your life. I think the silver adds tensile strength to the stuff, but the tin is what does the "bonding" (it's not really bonding. I just don't know what you call it when two dissimilar metals share atoms on a molecular level.)

    I thought the same thing too. Package said one thing. MSDS said another. the Home Depot sales literature was based on the package. It's all good if it works for you. I buy it too for non-critical applications.

    I'm just suggesting to take care with respect to the material itself. It may not be what is on the package label.
