Generally you are correct, especially for soft steel jacket that sticks to magnet, and for performance of spce.
I will just add that the latest lot of S&B in 9.3x62 did not cycle the bolt in my semi auto rifle, while other cartridges tested did cycle. (sako Hamerhead, and geco).
Another point - they do have wide variety of ammo, classic and premium bullets as you have noted. And they are very attractive in price.
However biggest lack in their production is actually lack of 375 H&H, or 458 win mag which are most common DG calibers, and have their own piece of market and consumers.
