I make a list and make the drive to Williams. I have never had a problem getting reloading powder there orhand gun bullets, For both hand gun and muzzle loader. I did at one time have trouble buying the same brand and type of sabot from them every year. MMP bulk solved that problem. I have no trouble with any type of primers or caps either.
Rifle bullets are usally in stock an on a shelf too. Not unusal to walk out of there with a couple hundred dollars worth of primers, caps, bullets and powder. It is normally a twice a year trip though at most.
T 7 I buy at Wally world at the end of the season usally 6 to 7 pounds at a time. I have 11 pounds on hand now.
