I have 4 traditional rifles that I wouldn't be afraid of using at 200 yards on elk.
A 451 English sporting rifle 1:20 twist with a Soule sight, a hawken 50 cal 1:24 twist with a 6x Malcolm tube scope , my GPH 54 cal with 1:32 twist and a 451 Gibbs with a 1:18 twist with a creedmore sight. Anything along those lines will serve you well for what you want to do . Heavy lead to sabots adds lots of options. I will leave it at that so as not to get into info overload for you
