Bar solder

I have 13 lbs of bar solder marked 5/95. According to Google, that is 5% tin 95% lead, that works out to a 19 to 1 alloy. I shoot 20 to 1, close enough for me. I also have several bars of SN1F marked solder. Google says that is 99% tin. Any thoughts or comments?
Mike

When I mix my 20-1 I cast bullets from my go to mould that should weigh around 208.8 to 209.2.  If they are out of that range I add tin or lead to get them there.   Cast some of the 19-1 and see what they weigh.  Who knows they may shoot bette than your 20-1

Why did I flash on an image of a Medieval alchemist hunched over a workbench littered with packets of frog teeth, saucers of bumblebee urine, and bowls of fair maiden's night soil? No wonder Jack keeps his bullet casting lair under tight lock-and-key.

I use bar solder in my alchemy efforts whenever I find it. Ditto old coils of resin/flux core solder - I figure there's built in flux for the lead pot. My Dad and Gramps (both prolific solderers/welders) probably spun multiple times in their graves when I gleefully turned their hoards of solder into bullets.

SN1 and SN1F are both 96.5% tin.
SN1 remaining % is silver
SN1F remaining % is silver, copper and sometimes antimony.

They are both 'Electrolytic' solders,,the highest purity classification.

The solders are used in electrical soldering in specialized/ expensive type electronics.
Defense, medical, etc.
Expensive stuff due to high purity of it.

The SN1F has a lightly different characteristic from SN1 when used.

Do you think the additives would make little or no difference if I used the SN1F as tin.
Thanks Mike

I have used that for my alloy of 20:1 and cannot see any difference in some store-bought alloy. It is only a tiny variation, and you may make as much or more error in the weighing of the parts to the mix anyhow. The traces of other metals seem to be of no consequence either and may make the whole easier to incorporate and cast.

The little percentage of silver will help with the werewolves, or at least the weresquirrels.
