I have 2 788's in 30-30 and shoot only cast in them. Reason for 2 of them is that the extractor is reputed to be somewhat fragile and difficult to obtain replacement parts. Also have a 788 in 44 mag and the extractor broke shortly after purchase. The lgs where I bought it replaced the extractor with the advice if I ever came across those parts buy them as Remington discontinued stocking them some time ago. I have been told that the rimmed 778's should be loaded only from the magazine and not single loaded from the breech. Seemed like good advice considering the fragility and scarcity of replacement extractors.
All 788's are great guns that are accurate and a good value for the price.
