Med-size game 270wsm large game 300wsm the only two i need !!!
No argument here, but it occurred to me after reading your post. Can’t the same be said for any .308 diameter round from about .30-06 up to .300 RUM?I’ll jump on the .300wm band wagon. Depending on the game you can load up anything from a screaming fast 125gr to a heavy hitting 220gr so you have pretty much all the game in North America bigger than a fox covered.

Not quite. I don’t think the 06 pushes a 128gr out to 3400fps or delivers a 220gr with 5100j of energy.No argument here, but it occurred to me after reading your post. Can’t the same be said for any .308 diameter round from about .30-06 up to .300 RUM?
And using your logic there are a plethora of diameters that the same can be said.
True however it’s close enough on game that it doesn’t matter. A quality 220 Gr bullet from an 06 will penetrate a big bear length wise, and 130 Gr .30 cal bullet at 3100 FPS will do anything one at 3400 will.Not quite.

Agreed. I remember decades ago the same being said about 30-06. The old timers said if you could only have one that was the choice because of the variety of (then) available factory ammo.True however it’s close enough on game that it doesn’t matter. A quality 220 Gr bullet from an 06 will penetrate a big bear length wise, and 130 Gr .30 cal bullet at 3100 FPS will do anything one at 3400 will.
While there is a difference on paper, in the field on game it simply doesn’t matter that much.
My point being the old saw about loading a .300 WM up or down to suit your needs can be said about multiple callers and rounds. The key is to be a hand loader.

I'd think the flatter trajectory would make making the hit easier...

While I hear and agree to a point with what you're saying, when it comes to trajectory...velocity still counts. In your example with the .308 220 grain, 30-06 vs .300WM there's just about a 200FPS difference between the two.
I was just having this discussion/argument with my son. In our case comparing his load for 300 WM vs. my "worthless" 30-06. Let's assume that at 6 inches of drop you should probably start compensating for your drop, either by scope adjustment or holdover. When you compare the ballistics tables for our loads the 30-06 hits that threshold at about 285 yards while his 300 does at about 300 yards so the window of advantage is only around 15 yards. Over 300 yards, BOTH of us are making adjustments. In addition, trajectory adjustments have never been easier with today's rangefinders and systems such as Leupold's CDS dial. Considering all of that, the advantage of a fast round comes much more down to energy than trajectory.
That would be a slight theoretical advantage past about 300 yards. However with modern optics and stadia lines and dials the velocity for flatter trajectory schtick has kind of become obsolete. It has in my world anyway. I can bang steel at 600 yards just as easy with a .308 as I can with .300 Dak with a dial installed.
Not to mention the critters and the style of hunting I’d be doing with a 220 Gr round out of an 06 or a .300 WM would not require long range shots. If I was using 220 Gr bullets in a .30 cal it’d be for back up shooting on North American DG or possibly for hunting big critters in thick cover where the shots are close. With premium controlled expansion bullets there is not really any reason to use anything heavier than a 180 Gr bullet in a .30 cal unless you’re pushing the performance limits like a least one professional AK brown bear guide does using his .30-06 as a back up gun on the Alaskan Peninsula he shoots 220 Gr partitions I think.
The other reason to go heavier than 180 gr is to shoot optimized heavy and long bullets for extreme range and in a .30 cal and for that you’ll need a 1 in 9 twist rate like is done on the .300 PRC. Most factory 06 and .300 WM use a 1 in 11 twist which will not stabilize most bullets heavier than 200 gr bullets anyway.

(Eagle103 and I were posting at the same time, so there is a lot of overlap in our posts.)
I agree, but while I'm a huge fan of Strelok, CDS and mil reticles, I believe there are situations when there's not enough time to make the calculations and the flatter trajectory or the old MPBR style of sighting in pays off. For instance my recent antelope hunt in WY, there was no time to dial as he was moving. I went with an initial lazed distance than an "guestimate" of a holdover based on the distanced he'd covered angling away. The buck managed to cover about 75 yds between initial spotting and when I made the shot.
I'd run the tables myself, but this should suffice for a theoretical discussion. Chuck Hawks for instance calculates MPBR of both as for a 6" kill zone (3" of drop, the most I've ever used personally was an 8" zone for elk, giving 4" of drop):
Cartridge (Wb@MV) Bullet BC 100 yds. 200 yds. MRT@yds. MPBR (yds.)
30-06 (180 Sp at 2700) .483 +2.7" +1.5" 3"@125 269
.300 WM. (180 Sp at 3070) .483 +2.5" +2.3" 3"@150 303
So at least by his tables a 34yd delta.

So IF I had a .300WM and subscribed to the MPBR way of doing things, no hold over or dialing in for me at 300yds.
Again I agree that the modern reticles, ballistic software etc. have negated the need for the flatter shooting cartridges (somewhat), there's still times when a tighter trajectory does have an advantage.

Welcome to THR!!!Ok, here goes my old school list:
Of course, any of these will work on just about anything in North America.
- Timber hunting elk: Open sight .45-70 govt, Hornady 325 grn
- Open country elk: .300 Weatherby, 180 Nosler AB
- Antelope: .257 Weatherby, 110 grain AB
- Mule Deer: .270 Win, 145 Hornady ELD-X
- Mountain Goat: 7mm Rem Mag, 175 Nosler Partition
Fun to have options to try, right?
