Ive been trying to decide on new molds for several calibers i shoot and a few that i may begin shooting soon.
Of most concern to me are 357, 30-30, and 30-06. Lesser but still relevant are 45 colt and 44 mag.
I did some searching about this ageless debate, and found a few consistencies in peoples attitudes toward the different lube groove styles. Let's leave out lee tumble groove designs please.
General consensus i found was that:
-square lube groove molds dont drop boolits as readily as round
-square lube groove boolits hold lube better than round
-square lube groove boolits may shoot with better accuracy (debatable, or minimal)
While accuracy is always a goal of mine, i also appreciate ease of production and lube application. In fact until i get another 10-20k rounds under my belt i bet that i would not see the minor differences in accuracy between the two designs. I realize that it takes diligence and patience to become expert.
So that leaves my concern in the realm of ease of boolit production and ease of lube application.
I would be tumble, pan, dip, or hand lubing these boolits as i dont yet have a lubrisizer.
It seems to me that like so many questions people post here, it is largely a matter of personal preference. But i would appreciate some feedback on WHY individuals have tended toward one design over the other, and the differences they have seen while casting, and applying lube. Lube retention during handling is also important to me.
While you're at it, what lube is being used for the design you prefer?
Thanks, good shootin to you
