I was also going to use my grandfather's rifle to hunt deer with in the 1980s. It was an 1873 trapdoor Springfield that he acquired in the early 1900s. I did not take it though, I decided not to. But in my neck of the woods, it was not all uncommon to see an original trapdoor Springfield on the rack of a gun store in the early 1980s. So my point being, is firearm usability was always determined by the owner, not by style. Your points are well taken sir, I enjoyed the exchange of thoughts.I think going by that logic, you wouldn't be wrong to take an 1895 Chilean Mauser, but a modern bolt action rifle popular in 2000-2025 would be more appropriate for someone "reenacting" the first quarter of the 21st century as those would be what are more commonly seen in use in the period. For example, some of use are still out there shooting traditional muzzleloaders, including antiques from over a century and a half ago, but we are oddities, not the norm of our era.
