I've ordered powders and bullets at least a dozen times. GTG.
Midwest Powders often have limited load data, but I've been able to work up loads and use many of them.
Be mindful that many bullets are pulled, so they may have minor (or significant) marks on them. Some offerings are new product (new as in not pulled, not just a new for them offering). The LOS bullets are virgin product. The TMJ are plated, the FMJ are jacketed.
One time I had some .45 bullets that were under-sized (about .450") and I called them on it. They credited my purchase price. I've since seen bullets that were listed as being under-sized.
