I ordered two different orders of 1000 124 gr. 9mm from Dillon. It took about 30 days per order. Then I was cleaning up a box from the move 5 years ago and found several thousand cast bullets I made to sell in the mid 90's. For 45's and 38's I've been using patriot bullets/patriot casting in Columbus, Ohio. (I Bought about 25k 200gr RNFP 45 and 4k 200 RNFP 44-40 several years ago) but I talked to Mike, 2 weeks ago, he is having no problems keeping up with orders.
People always like to "Borrow" but never return to my stash, so I just give them Patriot's name now!
I always had great service from Bear Creek, in Northern California, but someone I recommended them to, said the were basically worthless now.
I try to keep a thousand or 2 of the jacketed bullets I use on the shelf, and pick them up on sale (I just opened my last 1000 Win FMJ from the 25k I bought in 1984, so I'll be keeping my eyes open for a sale!) I do powder and primers the same. (now is too late to stock up!)
