I already have and love a .264 win mag that does all my heavy lifting. I have kinda thought about a 6.5-300 Vanguard lately since they are so cheap but ammo is kinda spotty still so I will wait till they over produce and the price crashes. As for the question at hand I looked up some front runners heres what I found:
6.5-300 WBY: -3 from the barrel tip to 300
.220 Swift (40gr): -4.5 from barrel tip to 300
.257 WBY (87gr): -5 from barrel tip to 300
28 Nosler: -4.8 from barrel tip to 300
30-378 WBY (175gr): -6 from barrel tip to 300
240 WBY (85gr): -6.5 from barrel tip to 300
7mm Rem: -8.5 from barrel tip to 300
270 WIN (130sst): -9 from barrel tip to 300
260 REM: -10 from barrel tip to 300
I used gun data.org for all the data and this is actual drop from the barrel not the line of sight. As you can see the 6.5's have it to 300 yards. The big 300's will out run the smaller bullets further out but the speed/BC combo on the 6.5-300 is unbeatable at 300. My little .220 Swift held its own to 300 as well as I figured it would, still the best caliber ever invented. Thanks for the input.

taking out all the smart acs comments , what you really want is to adjust your scope to get point blank range to be close to 300 ... for example a 308 with 168 grain sighted in 2.5 high at 100 will still hit within a 5" vital zone at 290 .. so if you plan on hunting whatever , just estimate vital zone (5 to 6"???), adjust your 100 yard zero to hit that 5" target no matter what by just aim and shoot ... i think that's what you really want ... you'll hit a little high up close and a little low far .. but make a kill regardless without adjustments
after that, you can pick calibers that may have a little less deviation based on speed and bc ... but for the most part , just point and shoot ...
phone apps like ballistic AE have a point blank range target size that shows you the exact calculation to achieve just that.. then , just practice in the field and you should be golden...
hope that helps

Those Lazzeroni Calibers are impressive for sure. I did not include them since they are not very mainstream. No free lunch with any caliber though, burn more powder if you want to go straitter (For some reason my Spell check is not recognizing this clearly real word). The 6.5-300 is the winner for sure and probably would be for many yards more if I cared to look. Just for comparison sake I will expand my original list so guys can really see where the different calibers stack up:
6.5-300 WBY: -3 from the barrel tip to 300
.220 Swift (40gr): -4.5 from barrel tip to 300
.257 WBY (87gr): -5 from barrel tip to 300
28 Nosler: -4.8 from barrel tip to 300
30-378 WBY (175gr): -6 from barrel tip to 300
240 WBY (85gr): -6.5 from barrel tip to 300
25-06 (85gr): -6.5 from barrel tip to 300
.264 Win Mag (100gr): -7 from barrel tip to 300
7mm Rem: -8.5 from barrel tip to 300
270 WIN (130sst): -9 from barrel tip to 300
260 REM: -10 from barrel tip to 300
30-06 (165gr): -11 from barrel tip to 300
350 Rem Mag (220gr): -14 from barrel tip to 300
I was surprised to see how well the 25-06 did. It is a real flat shooter to be sure.
