Brass uniformity affects a few things – but how much of a difference can you expect from brand to brand? If you have highly consistent brass you’ll notice similar life spans across your reloads, as they stretch at the same rate. You’ll have near identical case capacities, the result of uniform wall thicknesses. There’s a whole lot more to case uniformity, but what I want to focus on is the amazing difference from brand to brand.
The SKS is one of very few semi-automatic centrefire rifles that allow for cheap and cheerful shooting in New Zealand. The rifles themselves are amongst the cheapest autoloaders around and the steel-cased ammo is a bargain compared to other centrefire rounds, as detailed in a previous post on the venerable 7.62×39.
