Nosler does make a lot of bullets for other people.....but you will not get them to admit it!! I have a couple of friends that work there and when you ask what they are running it is always...."bullets". Finally confirm they are working on a contract but it is still just......"bullets".
Remington makes bullets for others as does Speer. Pretty good trades going on between the industry leaders. Winchester used to provide a lot of the "generic" bullets to some of the retailers. I am not sure who is making them now. I hear that the Varmint Nightmare and the Dogtown bullets are the same...I don't have any so cannot confirm.
My post above about the Outlaw bullets was in good fun. Joe is a friend of mine and we shoot together a couple of times a year. He has stuff to make those 41 bullets but I haven't seen him shoot them in competition yet. My shooting buddy and I went together and bought dies and press. We make 7mm, 6.5mm, and .22 bullets. We shoot all of the ones we make in competition. New 6mm dies are on the way. For revolvers, we only shoot cast. We have a load with an LBT bullet that shoots pretty darn well out of a revolver.
Glad you didn't ask for cast bullet makers........
