I actually favour S&B ammo for most of my surplus rifles. My Nagants, Kar98ks, my Ljungmann and M96. Havn't had any problems with any of them.
Accuracy isn't quite up to snuff with some handloads, back when I was able to handload, but it's definatly better, or at least on par with the vast majority of surplus and other factory ammos out there.
And yes. It's loaded a lot hotter than 90% of North American factory loads, but still well within safety margins, and under each cartridges respective military loads.
