I should probably stop being so old school, im still hesitant to get into new calibers because and I'm sure I've said it here before, but a few years back I was always chasing bigger and bigger magnums, I spent thousands of dollars on weatherby magnums, ammo, range time and eventually started backing down back to more conventional calibers.
The issue is that aside from hunting, I do like taking my nice rifles to the range to shoot just for fun and practice, I even did a long distance race/target event with one of my hunting rifles and got 2nd out of like 25 people and they all trained specifically for the event.
The issue was that every time I'd take a 340wby mag to the range, isn't spend like 90 dollars on ammo, I do alright these days. It 90 bucks a weekend plus whatever other ammo I shoot in other rifles/pistols was adding up to like 6-700 dollars a month to shoot. I stopped shooting those specialty calibers and sold off most of them except for a few hat had sentimental value.
My dad goes and shoots weatherby stuff all the time but he's retired and financially set, I like the 06, 270 and 308 because I can actually get out and shoot a box or 2 on a Sunday afternoon and not feel bad about dumping a days salary down the range lol.
If I was going to get something new though, 300wsm would be a front runner. I'll check it out more and look at those tables, thanks for posting that.
