I have an opportunity to purchase a pre-war Heym combo gun with 16ga over 7.8x57 (stamped on the barrel). It has what appears to be Deluxe grade engraving, good wood - has not been a safe queen and has some handling/use marks. He's asking $1500.00 USD

Questions:
1. I have looked through my reloading books and have done an Internet search to try to find out if 7.8x57 is actually the same as "standard" 8x57 Mauser without much in the way of 100% conclusive answers. I don�t want a �show gun� I want �a shooter� and want to be able to find reloading components without having to purchase custom dies and brass.

2. I know the Heym name is excellent and is his price "reasonable"? (if I can find reloading supplies).
