I wonder with ammo like this if there's any reason to own a revolver in a larger caliber other than competition shooting.
I mean, I love my .45 wheelguns, but it wouldn't be much fun hauling them around in the woods when a .357 that weighs half as much is available.
This is why I settled on 10mm as my ideal woods carry gun and 200 grains is the max that .357 can shoot, but 10mm can shoot a 10% heavier projectile and shoot 200 gr hollow points that will expand.
Anyway, I love my .45 Redhawk, but as a gun for carrying it's far from ideal, it's performance on a man tho is excellent and it can pretty much shoot about 6 different .45's (GAP, ACP, Super, Cowboy Special, S&W, Colt) plus the .45 Colt holds a fair amount of birdshot and two .454 round balls.
That's all a lot of fun to shoot at the range, I have no doubts about the .45 for self defense, I know it can do the job on a charging bear, but I'm not interested in carrying it. That doesn't mean a big revolver isn't worth owning, they are if you have a good reason for owning one.
The versatility of the .45 Redhawk as a large reason why I bought it, but a .44 Magnum... it doesn't have that versatility and is a reason I have never had an interest in owning one. I know the .44 fanboys will read this and say something like "it's great in a rifle!" and yeah, it's fine in a rifle, but it's not significantly better than Ruger only .45 Colt loads in a rifle, nor is it better than .45-70.
