I’m a big fan of the m1917 Enfield. It has a smooth action, I like the cock-on-close, and the fact you can sneak a 7th round in it by pressing it into the magazine a little is unique to that era of bolt actions. It might not be the most aesthetically pleasing because it has a little bit of a belly compared to other Mauser style rifles is a quirk that makes me like it even more. It has a long sight picture and good iron sights especially compared to other WWI bolt guns, and the increased weight makes it nicer to shoot even if it would be more of a pain to carry compared to other rifles. It’s not as fast as the Lee-Enfield but still pretty quick too, and dogleg bolt handle does mean you can shoot it similar even if it is a little different.
I haven’t shot many bolt guns outside of WWI+II milsurps, but that one is my personal favorite.
