상품설명
Sold by the Ingot ~ i.e. 1 Pound This ratio of~ 87.25% Bismuth, 0.75% Antimony and 12% Tin is the best ratio we have come up with as a substitute for lead. This alloy melts at about 395 F and is best cast or poured at about 500F. Testing the hardness with a Lee Hardness Testing Kit, we came up with an average of 19.3 on the Brinnell Hardness Scale, although there was a range during the testing. The bismuth gives you the weight (as close to lead as possible) and the tin helps holds it together and makes it less brittle. This is an alloy we have been asked to make a few times so we decided to make a larger batch and have it easily available to everyone. As we are still testing this alloy, we are offering it at a lower cost and asking customers for feedback and their thoughts on how it works. Yes, we know it costs way more then a lead version, but hopefully with more volume, we can offer better prices in the future. One item of feedback we got from our customer follows: I have some results from shooting this alloy over the weekend, very favorable in the limited testing I did. Accuracy and high velocity is not a problem if the bullet fit to the rifle's throat is right. No bore fouling, no problems at all. I even cleanly killed a small whitetail spike buck with my .223 Saturday using the alloy you sent. I documented the entire work here on this bullet-casting forum, Load information, approximate velocity, and target ranges are in the text with the appropriate photos.
