mcwoodduck: I'm not speaking for the gunnut69 here but I have changed out the front sights on Mausers before, cheaply and easily and have gotten a much better sight picture in return. SARCO or SAMCO usually sell front sight kits or packs of target blades (square tall front sight blades) for Mausers that can be worked down to give you poa impact at 100m, seeing as how most Mauser rifles I have ever shot have the lower inverted V front blade designed to shoot high at 100 but be on target at 300m.
The sight blades are for the Swedish Mauser but I believe all Mausers, save the FR models, have the same size dovetail sight base. I used the Swedish Mauser blades on my Yugo M48A and what a difference. To enhance the overall sight picture I used a small Swiss file to 'square out' the rear V sight for a much cleaner overall sight picture. I think the entire pack of 3 or 4 sight blades might cost about $10 or so.
I know the 8mm Mauser 98s shot high at 100m and I think the 7's were probably the same but even if not, a nice square front sight blade really helps. Also, I believe that Brownells carries replacement front sight blades (some with a white stripe, too) for Mausers. You can also check with MidSouth and some of our other sponsors. Good Lcuk. I'm hoping the gunnut69 may have some better suggestions that I can put to use next time I too decide to fiddle with a Mauser front sight...
