In life, some things are inexpensive, some things are cheap, and some things are worth more than they command. An inexperienced eye cannot tell the difference betwixt the three and so defers to present and individual value.
I’ll save you the trouble and say that good cartridge brass lasts and is worth it to pay some small premium for reliability. Simply, upon detonation, it obturates, seals and is ejected in fractions of a second should everything operate as it should and sometimes…it doesn’t do any of that.
A rimless cartridge can shear at its rim, and let me warn that should you not have a plan nor a prayer in that moment, you are simply dead in the water.
It’s easy enough to remedy, if you know what you are doing, but slender cylindrical rods are not often found by happenstance in nature and if it’s dark and you need a second shot, it’s not going to happen.
Buy good brass. A lot of it. Because the sun is setting and one might not shoot enough to understand the necessity, but it is wise to acknowledge the present and individual value of appearing prepared.
