X2 on the .300 Savage then. Ammo available at Canadian Tire, 5 loads still made, chambered in COOOOL rifles. Classic pumps, autos, levers, bolts....

7x57 may not be "nearly as popular" but it has a loyal following among those "in the know": experienced and informed hunters and collectors. It has survived 100 years, unchanged, for a reason. I love my 30-06 Sako and my 308 Savage, but overall, the 7x57 gets the nod in almost all cases.
The guy asked about getting something comparable to .303 brit. The only answer that fits is 308 win. It is nearly identical balistically to .303, Is probably one of the cheapest calibers going, and will fit the needs of 99% of all hunting scenarios. Seriously, debating about a few inches here or there and a hundred or two lbs of energy at 500m... C'mon guys. Splitting hairs. And can we PLEASE stop calling bullets pills?... Sorry ID, Its a big time pet peeve.
Btw, im not knocking the 30-06, it is a great cartridge also... but it is not the right answer to the OP's question in my opinion.

Nothing wrong with open sights (or scopes), depends on personal preference and type of hunting. Personaly, I prefer aperature sights.
Both the .308 and the 30/06 are good hunting rounds, but the .308 is closer to the .303 in recoil and report and so may suit the OP better.
There are some people that seem to have a minimal grasp of what sectional density and ballistic coefficient really are.
SD is simply a measure of bullet weight / bullet diameter. Since we are looking at all .308" bullets, the heaviest one will have the highest SD. 200gr will have a higher SD than 180gr, etc.
BC is simply SD multiplied by a shape factor that accounts for the aero efficiency of the bullet shape. If we are talking the same brand / type of bullet, then the shape factor will be very close to constant through the various weights. For example, Nosler Accubonds will have a very similar shape coefficient between the 150gr, 165gr and 180gr versions. Thus, the 180gr will have the highest BC among that group of bullets because it is the heaviest.
To say that 180gr bullets have the best SD and BC is far too general. It depends completely on your uses for that bullet. Yes, they have the highest SD and BC, but that is not all of the comparison because they also have the lowest muzzle velocity.
The lighter bullets will offer a flatter trajectory in close, but will lose out at longer ranges (say beyond 300yds). The heavier bullets shoot flatter at longer ranges and hold their energy better, but have a shorter maximum point blank range. The heavier bullets also offer better penetration thanks to the higher SD. If you are shooting at bigger, tougher animals like elk that may matter to you. If you are hunting whitetail deer, the flatter initial trajectory of the 150gr bullet may be more important than extra penetration.

Put a 220gr partition @ 2500fps in the 308 for moose.............Oh wait, that's a 30-06. 
A 308 is NOT a 30-06 IMO. (not that there's anything wrong with them other than I didn't like the one I had and an '06 is better. )

I will say I think 30-40 is about equal in power. With the added advantage of many more bullets to choose from, for the handloader. The 300 Savage has been mentioned already along with the Winchester cartridge that surpassed it. If you don't mind looking for brass and dies, 307 would be about equal too. (maybe a bit more energy, but I bet the dead deer would not notice the difference)
Edit: I often have felt an optically sighted Ruger #3 in 30-40 was something about perfect for a long day of deer hunting.
I beg to differ on that one. With the 308 and a 150 grain bullet, it travels at what...about 2,700 to 2,800 fps, something like that? In 30-06 it travels about 2,800 to 2,900. It is flatter. In 150 grain, I typically use 308 for deer sized animals.
The 30-06 with a 165 grain is superior and with a 180 gr...will be good for just about anything in N America.
There is a difference!
However, that being said, the original question was the caliber MOST comparable to the .303 and in my opinion, that would undoubtedly be the .308 Win - in terms of common, find ammo anywhere, any place remote.
Sweet mother of god, what the hell did I start lol. Not to 
but the .308 far as I know the .308 is 7.62x51 and the 30-06 is 7.62 x 63...if I'm not mistaken 308 short action caliber, 30-06 has more bang for the caliber. 30-06 springfield was replace by the 7.62x51 because military personal could carry lighter rifles and more ammo. As for trajectory I'm not too concerned, anything over 300 yards for me is not a shot I can make confidently.
I already own a .308 BLR sweet gun, but there's a large of sentimental value in it. It was my grandfathers so I try to keep in the best condition as possible. Those kolpin boots and the dirt roads has taken a toll on the bluing. Grandpa would have wanted me to retire it so I hunt with it only in the best conditions. But I wanted a rifle I can use for any condition new or old a rifle is meant to be used, if that takes a few scuffs, or a nick from slipping out of the treestand...it's happened, then so be it.
As for killing power it's just as important to pick the caliber as it is to pick the bullet type and grain. I shot a large doe roughly 100yards lung shot. she ran about 50 yards and lay down. I shot her in the neck when I found her. .308 180 powershok soft point. I seen my hunting partner knock down a calf moose 200+ yards lung shot. One shot and dead. .308 180 vitalshok noslerpartitionMy bullet didn't make a large hole in the lungs, his did. Also shot placement is critical, preferably close to the trail. lol
So I do agree the .308 is similar, guess I just didn't want to admit it. What's the recoil on a 270 like i comparison to a 30-06 and 308? As for the rifle I'd like an A bolt or a Tikka.

glad you asked.
Most common bullet weights used:
270: 16.5lbs recoil (130gr)
308: 18.1lbs recoil (165gr)
30'06 20.3lbs recoil (180gr)
Note that although the 308 actually has greater recoil than the 270, it actually underperforms in the 270 in terms of speed, downrange energy, and bullet drop.
308 loses to the 270 while providing heavier recoil and it also loses to the 30'06 while only providing 1lb less recoil. It's a loser cartridge.

Lighter? And? It still provides more energy to the target. I can provide pictures of what a good premium bullet in 270 can do to an animal. It's equally suited to moose and elk as the 308. Actually more so even though people often don't want To admit it.
