243 vs 270 for hunting

I have heard from more than one source that both these cartridges are excellent choices for wolves. Especially at medium or long range encounters. Two full time trappers in Inuvik used the 243 for about everything, but hides are thier primary cash concern.
These days you can locate 55-60 grain bullets for that 243. However 270 bullets even 90 grain have been known to almost blow a coyote in half.

If you are buying a new rifle go with the 6 Creedmore as it is 'twisted' for 105-110 grain class bullets, The 243 win is generally a 1:10 twist.

Or a rebarrel, a fast twist 243 Win, mine is 7.7 twist and will cover off bullets to ~115 grains.

So more options going the above route.
 
I have both. The .270 is WAY too much gun for coyotes unless you’re just into exploding them, which is a waste. It’s honesty off the table as a legitimate combo gun if coyotes are a significant part of the equation.
 
You mention "Southern Ontario". Note that some municipalities have their own rules on calibers. For example, Kingsville ON (near Windsor) has a maximum rifle caliber of 243 (see By-Law 10-2004 where it states you can't discharge "... any rifle greater than 6 millimetres (.243) in diameter carrying a varmint style projectile of more than 75 grains in weight"

So, no 270 in Kingsville. I have not checked other municipalities.

Then we can debate the whole diameter issue. Quoting the Ontario hunting regulations "A person hunting small game may not carry or use a rifle of greater calibre than a .275-calibre rifle, except a muzzleloading gun, in the geographic areas of Brant, Chatham-Kent, Durham, Elgin, Essex, Haldimand, Halton, Hamilton, Huron, Lambton, Middlesex, Niagara, Norfolk, Northumberland, Oxford, Peel, Perth, Toronto, Waterloo, Wellington or York."

Wikipedia claims that the 270 Winchester has a bullet diameter of 0.277" (7.0 mm). IANAL, but is a 270 Winchester projectile a greater calibre than .275?

So, IMHO, 243 is "better" than a 270 in Southern Ontario. I know you can buy (or reload) projectiles from 50-ish grain up to 100gr. All major ammo manufacturers sell ammo that they claim is good for deer.
 
I’m in sw Ontario also and depending upon your municipality, there may be further restrictions than .270 for hunting. Where I’m at it’s 243 or smaller, so 6.5 is a no go also

I'll stick with the classics proven rounds. These new rounds are expensive and hard to find bullets!

I can go Walmart in North bay and buy 243/270 rounds.

Thanks for the information very informative I'll go with the 243 . I have a 300 win mag bar for big game if needed.

Doing some more research there are a lot of rounds designed for deer if need be. I think a 243 will be fine for small to medium game. Besides read its one of the most accurate rounds.

I think it'd be nice in a browning bar mark 3 walnut stock. In a semi I can get rounds off quick if I needed.

243 isn't any more or less accurate than all of its contemporaries, including the 308, 3006, 300 win mag, or 270. The accuracy depends on the rifle and the quality of the ammo far more than what specific cartridge is being used. And the shooter of course.

Also, 6.5manbun (creedmoor) is getting very common, I've seen ammo for it at my local Walmart and Crappy Tire. Probably not long before you can get that in North Bay easily.

Can't really go wrong with the 243 for your purposes though! Have fun!
 
.243 is heavy for coyotes and light side for deer(still adequate no doubt)

.270 is heavy on coyotes but perfect for deer IMO.

Go .270 and dont look back. Id even suggest 25.06-.260 range instead of .243.

Or better yet, Buy a .22 250 and .270 and have two sweet dedicated rifles for each, ha

Problem I'm having is to much. I'm going to go with a few I really like and use them often.

.270 is not allwed in southern ontario as its .277 diameter thats why the 6.5s and 6mms are so popular . some places even 6.5 sarnt allowed hence the new 6mm creedmoore
so i use 223 in areas and move up to 6.5s for deer and my 416 rigby just for #### and gigles.. show up at deer camp with anything 416 and bigger and everybody hunts well away from me.

The regs are based on bore diameter which is .270 not projectile diameter which is .277 the MNR will confirm this.

Shooting the .275 Rigby is where things get interesting ...

I disagree... the bullet is the key... my buddy uses a .270 with monometals and it does surprisingly little damage, zips right through without really expanding.

270 is perfectly legal in SW Ontario, COs don't care about the .277 diameter.
 
depends on co.. theres a new one in southern ontario you would not like to run into.. hes very keen on giving fines and laying charges..."A person hunting small game shall not carry or use a rifle of greater calibre than the rifle known as a .275-calibre rifle, except a muzzle-loading rifle, in the geographic areas described in Schedule 4 to Part 8 of Ontario Regulation 663/98 (Area Descriptions) made under the Act." so 270 (.277 caliber)i dont think so....ive got two friends going through this right now...they were hunting coyotes.Check the townships you intend to hunt is the safest bet and try to get names or in writing of who you spoke to..
