I've purchased a few rounds from commercial reloaders with established business at gun shows but otherwise, no. I pick up reloads at estate sales and garage sales. I've pulled a few loads and weighed the powder and bullet weight.....more powder than any published source, any powder type for that bullet weight. Cannot trust handwritten label info on reload boxes. Perhaps ammo was moved from box to box. Maybe the reloader was distracted or had dementia.
Regardless, reloads by other people are pulled for the metal components and the powder fertilizes the garden.
