A couple of thoughts- first, a rimless cartridge may not be the best choice, these were really designed for rims- just an extra measure of reliability. Chapuis is good, Merkel and Kreighoff can be had in the next cost level up. Also, a real honest classic double in the original chambering is a possibility, in the same price range sometimes, which I feel will up the satisfaction level a bit, and sure will do the job! Also, an "original" will likely have a greater resale value- they are going up in value instead of the other way if you buy new- when the time comes. Of course, condition is everything, and there may be some load development involved- drat!
