Mar 30, 2018 · For the average shooter, reading the description on a box of ammo can make it feel like you’re deciphering a secret message. Ammo comes in many different flavors and between the terminology, abbreviations, and numbers, it can be overwhelming to figure out what it all means and bullet weight is just part of that formula.
I can't comment on jigs…for bullets you need to know the weight and with impurities in the lead it's tough to get consistent weight and soft or hardness of the lead. Wheel weights work too as Wayne mentioned. Again don't be doing this in your basement/garage. Might not bother you today… but old age points out younger mistakes.
