Been reading this thread because I bought a X5 Legion last month and had two case ruptures, extractor disappearance in slightly less than 200 rounds. Yes they were reloads, 4.5 grains of Titegroup with the 115 Hornady HAPs which Hodgden lists as the starting load. Son bought one also and had a rupture and blown extractor in about 200 rounds of the same ammo. Lots of case exposed by the breach like some of the pics on here. Haven’t made it all the way through a match yet
