My math is different.
3.59$ per hundred of primers
1.25$ per 100 rds of 3.7 grains of bullseye
2.50$ for 2lbs store bought lead for 124 grain TC
Comes up to 7.34$ per 100 or 3.67$ per 50. Please let me know where I can buy factory at that price and I'll go cash I'm my savings bonds to stock up. ( just knocked out 530 rds of 9mm in about 1 1/2 hours on a Dillion 650 taking my time)
