I don't know too many people that practice/plink with their "Hot" stuff. That's like plinking or practicing with Remington Golden Sabers. What a waste of money/ammo. If you're a reloader, you can load up cheap light plinking ammo for your pistols and the rifle. There is absolutely no reason to be plinking with hot 180 round ammo.
As for the 44 mag, sorry, but my personal opinion is that it is about the most useless caliber. Again; this is just my personal opinion. If I need that much power in a handgun, then I've been watching too many Dirty Harry movies. If I need that power in a rifle, I should buy a 30-30. The 357/38 has the advantage of being on the low end of what a 30-30 can do; yet not being to overpowering for a handgun. Plus, the ammo can be cheap. The 44 mag ammo is way too expensive. You can get 30-30 ammo cheaper. You can reload 30-30 for about the same cost, and have a much more productive round than a 44 mag. Sorry, there isn't one thing about a 44 mag that I find impressive. Then again, I don't believe in having only one weapon/caliber to try and do everything with. I have a 357/38 and a 30-30. (i actually have a shiite load more, but for this conversation, these too are being discussed). Between the 30-30 and the 357/38, there is absolutely NOTHING that they can't do that the 44mag/spl can do.
