I was checking out the Starline site today, appears 375 and 348 Winchester brass is on the horizon. Pricing is a bit puzzling though, as the 375 starts a bit under 60 cents a round delivered, which seems good, but 348 was about 1.70 a case, seems a bit high, since it's a necked down 45-70 case they've been making for years.....silver lining is at least it's being made. Hope both are available soon. Bill in MA
