My point is simple: as tools for hunting medium or even large non-dangerous game, the medium bores offer less effective range and inferior bullet performance with more recoil (or rifle weight to compensate). They are inferior across the board. Some of this is inherent in the bore diameter, some is due to the best bullets not being available. Of course that doesn't prevent anyone from shooting a medium bore because that's what they've got or nostalgia or giggles.
That is the answer to the question posed in the thread title - "Medium bore for light game?".
You keep saying they are inferior because they lack good bullets or bullet performance. How does a bullet that will kill an elk with an end to end shot at almost any ethical range lack performance? Or is this just more hyperbole?
As to recoil, every, and I mean every, 7mm mag and light 30-06 I have shot has higher perceived recoil than my 375. Yes, perceived is different than actual and is much more subjective. But I'd rather shoot my 375 all day than a 7mag.
Less effective range? How far would you like to shoot. I've made witnessed hits at 600y with my 375. Wasn't going for group, just for hits, but I hit my target, more than once. That's further than I'd ever shoot while hunting. So for me the range argument is moot. All I lose in hunting is a little speed and trajectory. Meh.
Rifle wright. Hit the gym. At 40, being of average out of shapeness, and having asthma, if I can carry my rifle in the mountains for days on end I'm not seeing a problem. I'm ok with it.
My point is, you come into the thread, post all manner of hyperbole, outright uninformed information, and when presented with counter argument and facts as to why you are incorrect, shift the goal posts, change the argument, and continue to harp on how 7 mag is the uber hunting round. We get it. You don't like medium bores. That's fine. Let us enjoy our backward, unenlightened, nostalgic ways.
Anyway, I've got a hunting trip to prepare for this coming week. Have fun with your tables and charts. I'll be I field hopefully killing a few deer with my 375. I've had my say, as have others far more knowledge than me. You win.
