I currently have two L.H. Browning Abolts (270 WSM and 300 WSM) but looking for something to varmint hunt and plink with in Southern Ontario. Can not use the 270 as bullet diameter has to be .270 or smaller. Would you chose a .223 or .243 considering my current guns.
 
Your .270WSM is legal in S.Ont. The law states:
You may not use a rifle of greater caliber than .275, except a flintlock or percussion cap muzzleloading gun... Bullet diameter has nothing to do with it, so have at it.
Regards
 
I'm sorry, thought caliber was determined by bullet diameter and although the common name is 270 the bullet diameter is actually .277 in diameter. Please correct me if I am wrong.
 
You will never go wrong with a 223 and light bullets. Barrels last forever. 243's are barrel eaters, 270's are slightly better, but it isn't a great varmint choice.
 
X2 on the 223 and they are such a hoot to shoot never mind cheap. Love mine and just upgraded to a CZ527 mini Mauser. Brass is so plentiful and seriously cheap to reload. I collect the brass for a range here to recycle for the club and 223 is by a very long shot the most common brass I see in rifle cals. 22-250 and 243 are scarce and have to go thru several collections just to get enough for a bag of 100. By that time I have already sold 1000 plus 223s easy and consistantly.

for a hunting rifle, barrel life is usually not much of a concern. Im sure a 243 will last a few thousand rounds before accuracy degrades to the point where hitting a distant varmint could be blamed on the rifle. :) Not many guys shoot more than 400 rounds a year through a hunting rifle so the gun should give good results for a number of years

I'd drop a zero off that 400, and maybe even a zero off the 40.
 
Good thread interesting re barrel life. I agree with the 223 re use. What is the opinion on 30 cal Winchester model 70 barrel's life. in 30-06.
 
270's

The rules read exactly as I had them in my post and it states caliber with nothing about bullet diameter. I have used a .270win in S.Ontario for years and I know other guys who use various 7mm's because bore dia is .275 which makes them fair game.

P.S. You should definately buy another rifle just so you have a back-up.;)

is the bore dia .284 on a 7 mm??
 
I own a .243, that I use for chuck hunting. I have had buddies that use the .223 and they always have a hard time bucking any kind of wind for a long shot. My .243 shoots straight and drops less when I use it with 75 grain vmax bullets.

243 destroys chucks as well, turns them inside out.
 
I asked MNR about this 275 thing. Rules were made by someone not techically competant. They were ttrying to block the use of surplus 30 cal at the time, as there was a lot of plinking going on with ammo that would bounce arond pretty badly.

They said '275" so as to make room for 270 Win.

But 7mm is 284, anyway youy slice it, so it does not meet the rules.

Buy a heavy barrel 223 with a 1:9 twist and you will have lots of options and ground hogs as far as you can see them. I have used one at 400 yards in the Orangeville area. great fun.
 
i think i would get a 223 as you already have a 270 which could be used on long shots or windy days.a bolt action for accuracy would be the way to go.270 is legal in ontario so your good to go .30. 30 . in our area of southern ontario is not allowed .the stupidity of our gun laws amazes me .
 
I see some people here do not understand the difference between bore diameter and groove diameter. A 7mm has a groove diameter of .284 but the bore diameter is .275, if caliber was a groove diameter measurement a .270win would not be legal either as the groove diameter is .277.

So any way you slice it 7mm/ 25.4=.2755" which is right on the caliber limitation making a 7mm legal in S.Ontario. So next time you get stopped by a C.O ask him like I already have.

"...Can not use the 270 as bullet diameter has to be .270 or smaller..." As daft as it is, it goes by the name of the cartridge, not the bullet diameter. It's not all of Southern Ontario either. Some municipalities state .270 calibre though. Nothing about the bullet diameter.
After all that, go with the .243. More versatile than the .223.
"...243's are barrel eaters..." Nonsense.
 
Well, I decided on a new Savage 10FLP .223. Picked it for $550.00 at Goble's, which I think was a really good price. Looking forward to the next weekend with some nice weather to try it out.
 
If any round stirs debate its the .243.....ok for varmint and ok for deer. Good short range sniper tool for the p[olice though...............
