We do live in the golden age of handgun ammo & that is some serious looking stuff! As far as cost goes it really not as bad as you think. Just shoot enough until you're dialed in then practice with a similar load for recoil management, etc. so you stay tuned up, much like Rey is doing for his upcoming bear hunt & you'll be on top of your game when the chips are down.
When you're actually hunting you can only hope to shoot a bunch of them on a good hunt.
Another thing you can do when testing new ammo if you want to see bullet results & you're limited on shooting distance is, figure what your velocity is going to be at 100 yds then download your ammo to that velocity & shoot it at 25 yds & check your results & see how your new bullets perform. Sometimes it's an eye opener.
