Results from Test Casting of new alloy

[Mike W1]

I didn't need the bullets yet but couldn't stand it anylonger to see how the alloy cast. Then got around to what I had. Cleaned the mould with Winchester Powder Blast and used NEI Mould Prep and made a few. No sorting when I cast them, the first bullets are included in that 117 though there must be one laying on the shelf with that odd number. I have found in the past if I want REAL accurate weights to use my beam scale and this kind of confirms that experience.

Weighed w/PACT BBK (I don't find this
scale to be repeatable to 0.1 grs
after extensive testing and those
differences in the 122.0-122.4 concur
with those prior tests.

If you did not have the mold adequately pre-heated I would expect your light boolits came from there. With most of your boolits from 121.9-122.4 you ain't doing too bad!

I must have missed a post about a new alloy.

Is it something other than the lead,tin,arsenic alloys that we know and love so much?

Nope. Basically just some observations about results I got and culling techniques.

Yup, dump the first 5 drops back into the pot, no matter what.
