I can't say Starline is better than Winchester but it is every bit as good. I have switched over to Starline for almost all of my handgun brass and use their rifle brass in 32-20 and 45-70. I have been very pleased with all the brass of theirs I've used. I haven't tried their 348 brass because I have an ample supply of Winchester brass. I certainly wouldn't be afraid of it. From what I've seen RCC is very expensive brass. Starline 348 isn't cheap but I doubt it's anywhere near what RCC will be.
