seb Posted February 21, 2011 Author Report Share Posted February 21, 2011 I will see if I can get hold of some antimony, what percentage are you adding to the lead? Seb Quote Link to comment Share on other sites More sharing options...
snarepeg Posted February 21, 2011 Report Share Posted February 21, 2011 Seb. Forget the dimmples, its only the starter for when you shoot the cartridge. Antinomy, about 4 percent but do you really need it?? its all in the mind, unless you are shooting Fitasc or ball trap and need that xtra tight pattern. Currently dropping into diesle, good shot but comes with the aftermath of degreasing etc, dont worry to much about cosmetics, live and clay pidgeons cannot tell the difference between soft and hard shot. john Quote Link to comment Share on other sites More sharing options...

Forget the dimples! I couldn't agree more! When perfect shot is driven up the barrel it is deformed like hell with dimples all round!! The ONLY reason lead shot is uniform and round is to facilitate uniform volumetric loading at the factory! The clays won't know the difference!

seb Posted February 21, 2011 Author Report Share Posted February 21, 2011 Someone gave me a brick of antinomy today. I already have my lead in ingots so I probably wont add any to the current batch but maybe next time I need to make some more ingots I will try it. Do you know how I can keep the drippers going without giving them a knock every 20 seconds? The one dripper keeps going all the time and I think it has a slightly bigger hole in it, I did clean them all before I started. I might make some stainless drippers, if I drill them 0.5mm do you think I will get no 6 to 7 shot from it? Seb Quote Link to comment Share on other sites More sharing options...
fruitloop Posted February 21, 2011 Report Share Posted February 21, 2011 is it pure atimony if so melt it outside as it gives off arsnic all i do is add a bit to my lead and then poor a ingot and see if it sinks if it does add a bit moor and repeat but as fc and snere says does it matter about the dimples i drilled my drippers .4mm and get 6/7 shotand have some at .6mm and get 5 shot but with the 5 shot it still needs a little tinkering as thay get little flat Quote Link to comment Share on other sites More sharing options...
snarepeg Posted February 22, 2011 Report Share Posted February 22, 2011 Seb. You will always get one or two that dont seem to run like the others. Are they the outer droppers?? as the heat to these is less than the middle ones. If you play a small gas flame on the offending drippers and they pick up speed, this could be your problem, also doing this will make your shot smaller as the flame cuts the tail quicker, a good way to get some nice 410 skeet 9s. The shot you photo/d is good anough for what you are shooting, probably bridge in anything below 20 gage, thats when you need quality/polished shot. Keep us updated. atb. john Quote Link to comment Share on other sites More sharing options...
seb Posted February 22, 2011 Author Report Share Posted February 22, 2011 It wasn't the outer drippers that keep stopping, the two outer holes have blanking bolts fitted. I have the thermocouple fitted to the ramp so I know its at the right temperature. I have a feeling I threw in some wheel weights when I cast the ingots, it is possible they were zinc, it was a long time ago and I cant remember. I will keep going with the ingots I already have and make a better batch when I run out. The antimony I have is commercial grade stuff that has been sitting around at work for years, I will melt it outside just in case there is anything nasty in it. I just need to make more shot now and get loading Seb Quote Link to comment Share on other sites More sharing options...
snarepeg Posted February 22, 2011 Report Share Posted February 22, 2011 Seb. If you have lead of an unknown pedigree?? put it to one side and use only when you havn/t a choice, have a ton of the same and it runs lousy. john Quote Link to comment Share on other sites More sharing options...

Antimony is an element, it contains nothing else; it is accumulative poison and melts at 904Kelvin. Quote Link to comment Share on other sites More sharing options...
seb Posted February 22, 2011 Author Report Share Posted February 22, 2011 I didn't measure the temperature when I cast the ingots but it was over a big gas burner outside and melted everything except the steel wheel clips so it is possible I got zinc in the mix. Are you sure antinomy doesn't contain anything else, I was told its impurities are arsenic and sulfide. Quote Link to comment Share on other sites More sharing options...

seb Posted February 23, 2011 Author Report Share Posted February 23, 2011 The antimony I have is commercial grade and still contains small amounts of impurities from the ore it came from. It still contains a small amount of arsenic, commercial grade antimony is listed to have 0.1 to 0.3% arsenic and a few other things but it is 99% antimony. It just depends how much refining it has had. http://onlinelibrary.wiley.com/doi/10.1002/14356007.a03_055.pub2/pdf Seb Quote Link to comment Share on other sites More sharing options...
