Back in the early 70's I loaded a lot of .357 ammo and Norma components were very inexpensive at that time. We had a big wholesale/retailer nearby who carried a lot of Norma components and he had very good prices. Norma components and ammo are top notch - at least the equal of anything made in the U.S. but their stuff is quite expensive now. The "carbine only" ammo was introduced by Norma specifically for the then-new Ruger .44 carbine.
