Just saying as I'm no expert BUT the original K98 Mauser military had a unique to Mauser set type trigger for safety/ consistency military application. If all the internals of original bolt and trigger are not worn out or rusted(corroded) to death this trigger really works sweet once you get used to it. I have two sporterized K98 8mm that I love. With Norma ammo or reloads you are 100% correct, there aint nothing on the n\North American continent stands a chance to a well placed appropriate bullet selection. I admire your devotion to maintain a family heirloom you can always buy more guns but there is something about a blood/personal relationship tie you can't buy. enjoy a lifetime of hunting and pass it on to a future generation. Yeah post war conversions were usually Weaver "K" scopes, or bargain copy knock-offs. Any vintage style new or old should fit the bases you describe.
