Gents,
Not to be argumentive, but the plain facts are that in todays world, the 357 magnum and 44 magnum both can readily be reloaded to almost (but not quite) duplicate 30-30 ballistics. IMO, the 30-30 has become as obsolete as the typewriter.
Now, in a couple of months, I'll be 70 years old and have spent a lifetime in the outdoors. I still have my first deer rifle in the safe. It's Model 94 Winchester I got for my birthday in 1959. It's seen more than its share of time in the woods and harvested a lot of game. But, as Star Trek's Dr, McCoy would have said, "It's dead, Jim."
Distance? Lemme tellya, Pards, I have a 1000 yard range on my ranch. I can ring the bell on an 18 inch gong at 225 yards with regularity with any of my lever rifles and iron sights.
If you look closely you can see the plates set out on this day (I was chronographing loads this day).
Anyway, the simple facts are that i can do with a 357 magnum or 44 magnum just about anything I could ever do with my old Winchester... and in most cases do it with greater authority. My old 94 Winchester has been a safe queen for many years now (and no, its not for sale).
