I ordered some brass cases from Starline the other day,and then received a call from them saying they didnt have any 9 largo brass in stock and wouldnt have any for approximately 6 weeks,however they did have some nickeled cases.I took half my order in the nickeled and told them I'd take the rest when they had it.I dont have a ton of reloading experience,mostly.45 auto and.38 special.What I am wondering is if there is any big difference between brass and the nickeled stuff.I looked on Starline's website and they dont advertise any nickeled cases that I could find.I know plenty of factory ammo is loaded in nickeled cases and alot of the .38's I've reloaded are also ,as well as some .45. Is there any differece between the two?? Joby
