A little while back I bought a 454484 mould off of a friend here at CB and had Buckshot hollow point it:
My first results were dismal and I decided I needed to add a little tin.So my next batch,I added about 1% tin to my WW+range scrap alloy.I cast these up today"
The mould was throughly cleaned and up to temperature,but I was still having trouble getting "perfect" boolits.I varied my casting technique as far as speed of production & pin removal timing.
What do you find works best for your hollow point casting?
