Found some of this 55 grain FMJ 5.56 mm recently, supposed to be M193 spec. Advertised velocity is 3300 fps from a 23.5 inch barrel, so it might make spec out of a 20" barrel. Have any of you shot this stuff, or seen accuracy or SD figures on it?
Only thing I've shot it out of is my AK's and SKS's ghostrider. They make 7.62x39 and 5.45x39 (hard to find those but they did). Like the quality of their ammo way and above Wolf ammo for shooting myself. Can't tell you anything else about them though since I've never seen any statistics.
I shoot a bunch out of my .45s and have found it to cycle well and reliably but isn't ballistically very secure
I have shoot a bunch of their buckshot testing a Moss 9200M. I had no problems. The shells were a little smokey compared to fed. but fuctioned 100%.
The great thing about S&B is it's good quality brass cased boxer primed but cheaper than commercial ammo. I use there 303 brit and 7.62x25 with great results and the cases are great for reloading. In fact the cost of ammo isn't much more than the cost of new brass plus you get to shoot it first.
