If you want to shoot your gun and have a it in very useful calibre, there is no gun IMHO that has optimum balance of power, recoil and gun weight as 41 Magnum in Blackhawk or S&W 57/657 without underlug. I personaly have Bisley with 7,5 barrel and like it more than 357, 44 or 45. If you are silhouette shooter, 41 Magnum is the top choice. Excluding 4 inch and shorter 38/357 as predominantly self defence revolvers, any sturdy 357 revolver with 6 inch barrel is basically the same weight as 6-6,5 inch Blackhawk or 57/657. As an outdoor gun, 357 is the best when loaded with 180 gr bullet and full load using slow burning powder. This is formidable combination, but where 357-180 stops, similar bullet weight and velocity in 41 is just a fairly moderate load. When I go on the range, I like to have the load that is powerful enough, yet not punishing for hands, and found that 200-220 gr at 1100-1200 fps is just that. And as a result, I can shoot all day long without fatigue. I tried 250 gr from 44 at same velocity, and found that after less than 100 rounds I feel bit tired with tingling in my hands.
Somebody might point to plinking loads from 41 Magnum? Not my cup of tea, for plinking I use to shoot 22LR. On top of that, loads at about 800-900 fps are not enough flat shooting on distances beyond 50 meters. Heck, if I want such loads I will just go with 40 S&W.
Now, if you want top load, take 260 gr or heavier slug with large meplat, use full load of slow burning powder and such load will kill cleanly anything smaller than grizzly. If I want more than 41, I will skip even 44 and 45, and get 480/475, or even better, one of those 500 revolvers. Nothing wrong with 44 and 45, but those larger bores could lunch heavier bullet with even larger meplat. Recently, I found information that Linebaugh is now making almost all his big bore in 500, just few 475.
Back to 41; yes, factory ammo is pricey. However, if you want to shoot, you have to reload. If you reload, you need reloading components, and in that respect loaded round is just cent or two more expensive than 357.
BTW, if you are looking for quality 41 mould, here is the post about group buy (GB) for H&G #258
