the mauser makes for a good hunting action.
but not a combat weapon especially against the lee enfield
10 round mag vs 5
much faster to shoot and easier to load.
was winning battles and wars before the m1 and m14 existed and was still on issue when those two had faded away.
The Enfield had much better sights too.
I actually think the K98 Mauser was a pretty poor battle rifle. It had bad sights, a slow action and a low capacity. The only reason I'd rank it ahead of the Mosin Nagant would be the better craftsmanship and safety.
