Varminator I agree with you as you go up in caliber you get a better hunting round but some people like me just like to play with all of them. Like that 25 wsm ol' mike mentioned, that would be a fun one. You didn't go up high enough in caliber for the best hunting round off the 8mm rem mag case though. Necked to 338 it is the best long range killing machine of the bunch. About the time the 8mm rem mag came out sierra came out with the 250 gameking in 338. The highest bc hunting bullet ever made and was for years to come. I necked it up to 338 and also built a 340 wby for this bullet to hunt long range. They were awesome. Then I decided to open the bolt face on one of my mk 5's, got a 378 mag box from wby, necked the 378 case to 338 and man it was a new long range world for that time period. Then as long range bullets progressed into the nineties a lot of good stuff started becoming available to the average guy. But typically as the caliber went up so did the BC until you get to 338 where you reach the top, then it starts falling off beyond that. This is changing some now for example with people like Kirby developing calibers like 375 off the chey-tac case pushing companies to develop long range bullets for them.
For years the best killing long range rounds have been the 338's because of this. Yes, I can take my little 220 weatherby rocket and kill about anything I want with a well placed shot. But when I have pounded hills for a lifetime looking for that 40" mulie or 400" elk you can bet I will have my 338 with me. There is no comparison to a big caliber, heavy round hitting an animal. Shock effect and huge entry and exit wounds for trailing an animal anywhere so it can't get away. If you misjudge the distance or wind a little and hit a bit high, low or to far back in field conditions you have a much higher chance of recovering your animal with the 338. So why in the world would a hunter limit himself with a smaller caliber? I have seen hundreds of animals for many years from little whitetails to big grizzlies, elk and moose shot with all kinds of rounds and I shoot a 338 for long range when I am after serious trophy animals.
A guy can build a 340 wby or 338-8mm rem mag and not shoot the barrel out in a lifetime. Even up to the ultramag case it would last the average guy a lifetime. So why in the world would anybody shoot anything other than a 338? Why do they even build rifles in anything else? With the light kicking 338 winny you don't even need a muzzle brake
and it will easily take out large game at a half mile and is super accurate. Just line my cabinets with all the 338's.
With all that said I own over a hundred centerfire rifles in all calibers in who knows how many wildcat configurations and I love to shoot every one of them because they are all fun to shoot. Yes, I might could have made better choices with some of them but they all killed most everything I ever shot at so I really can't complain. I wish I had a dollar for every campfire argument from the 60's to the 80's about how much better and how much more power either the 270 or 30-06 was or had. Get the best equipment you can afford, load it responsibly, learn how to shoot it well and you will probably be happy. No, I take that back, you will probably still be like me looking for that perfect gun as you build number who knows how many.
Varminator thank you for that post and believe me I am not attacking you. I guess it just tripped a switch. Everyone is right in this argument. I enjoy taking a deer or antelope just as much with my little 243 AI as I do with my big 338-378. They are all just fun to shoot so I guess that is why they make all kinds.
