I now reload all my calibers (.380 ACP, 9mm, .45 ACP, 30/06, 350 Legend, 450 BM, .50 BEO, 7.62 x 39, 7.62 x54 R, .300 BLK, 5.56, .224 Valkyrie, 6.5 Grendel, 7.65 X 53 Argentine, 6.5 Carcano, 11mm GRAS and probably a few more forgot). I generally try not to reload 9mm because the cost of the primers. Primers cost the same. One primer one boom I would rather use them on rifle I do however reload all .380 and .45)
I do it all on a single stage rock chucker. I use it amongst other things such as 3 scales (2 beam, 1 digital), primer pocket swagers, brass trimmer, calipers, The FART Franklyn arsenal rotary tumbler etc.. A lot of equipment is needed to produce good custom ammo properly In my opinion.
Snapbang a well known member here initially helped me in that journey. With his help I was able to get the primers I needed to reload my first round. It was for my 30/06. 150 grain fmj bt propelled by h380.
I think of it this way if I purchase a rifle or pistol I also must factor in the cost of a new set of dies and see how available the brass is and the cost of that. Finally what powders are used in that cartridge. The cross caliber use of powders is important to me because of cost.
I find it enjoyable customizing cartridges for each rifle. It is very rewarding; I know my ammo is carefully checked good ammo to use. Not to mention the cost saving on some but not all calibers. The 11m Gras is sold for about 7 dollars a cartridge I believe. Time well spent if you ask me.
