The 'how to' learning curve can look steep. For AG use, it seems a maximum hardness offered by 5% Tin to 95% lead, and at least 2% Tin is a good place to start. The sorting should be carefully done, and attention paid to the tail of the bullet; the release from the barrel is critical. For example, a boolit with a gas check shank is more likely to have the last drive band completely filled, and a rounded edge at the base has no effect on the release...cut off the gas check( for lightening, or shortening ), leaves the base forming a critical part again.

If the mold is pre-heated, the casting defects are much less likely. With .22's it is hard to get the mold up to temperature. Larger boolits warm the mold more quickly. Make sure the stream goes right in the center of the sprue hole. If it runs across the sprue plate the stream cools and defects become more likely. Careful positioning of the mold on a bottom pour pot will take care of this issue.
cheers,
Douglas
