WW alloy is always heavier but smaller in diameter. Lino is lighter but casts bigger bullets. You're on the right track with Unique powder; it's been around forever and is quite predictable. You should be able to load around 5.1 grains max with the bullets weighing what they are. Start low and work up is the best advice. Turn up the heat; your alloy isn't hot enough to fill out the mould cavities properly. 700 to 720 degrees should work nicely. CB.
If you want your children to follow in your footsteps, be careful where you walk.
Beware the man that only owns one gun; he probably knows how to use it.
I just hope my ship comes in before my dock rots.
