Do all hunting caliber under .275

This issue of the ".275" calibre comes up periodically. the Ontario Hunting Regulations make this statement
A person hunting small game may not carry or use a rifle of greater calibre than a .275-calibre rifle,

etc etc etc NOTE that it says RIFLE of a greater calibre etc ... it does NOT say a BULLET of a greater calibre.... Since there are two ways in which a 'calibre' of a firearm may be measured: either land to land OR groove to groove ... the RIFLE that we know as a .270W calibre measures .270 from 'land to land' therefore a rifle marked as .270W is a RIFLE that is NOT "of greater calibre than a .275-calibre rifle.

(important to remember the old adage: 'RTFT'! ... read the f'ing thing)

Some people will call the bore diameter the calibre .... maybe....as long as you accept (in the case of the .270W) that the bore diameter is the diameter of the barrel BEFORE the rifling is cut into the surface of the bore. In this case we can see why the 30/06 was considered a '.30 calibre' rifle ... not a 308/06

how many different reloaded ammunitions are you guys using in yer magazine for the said "oddity" rifles... ???

the cost of said factory would sway the usage of that chambering...... an with a month long deer season, 40 rounds would be plenty id have thought.

I shot my 275 over 150 times this summer doing load dev. Only fired it once in the field this fall.
 
This is my 22" factory tapered/fluted Rem 700 LTR in 6.8SPC (270 cal) that I mentioned earlier I load this one with 110gr Accubonds @ 2750fps the shot at the pumpkin was yesterday morning at 360 yards leaning on the roof/side of my SUV.

The scope is a Leupold VX3 4.5-14x40mm Varmint reticle I have this combo zeroed at 200 yards I held the first Varmint reticle line down on the top and the second line down was on the bottom of the pumpkin the stock is a Magpul Hunter 700.

This is the first time I shot this rifle this far usually only ever shot it out to 250 yards as you can see the shot hit 3" low this is the same rifle that I had to shoot the wounded blacktail buck two Sundays ago some neck shooting genius was off his mark by only an inch resulted in blowing the deer's lower jaw off.



I went back this morning I had left the pumpkin where it was yesterday took a few more shots at 360 yards again but this time I put the second reticle line dead on the center of the pumpkin.

Oh yeah I'm liking this combo...

Not bad for using the edge/roof of my SUV as a rest...

I dont know if 2506 counts as an oddity but im in need of my 3rd barrel. About 1800 rnds for the first and im pushing 2100 or so on the barrel i have now. Right now its about a 90 yard shooter for coyotes the way its patterning. 125 yards for deer

What's your vote?

I'd like to have a rifle that can hunt almost anything in Canada, but most likely deer and varmint in the short/medium term with some target shooting <300y. I know 6.5 creedmoor gets a lot of votes but I'm definitely not an expert.

Apologies in advance if this has all been discussed before.

Thanks for asking it again, I'm in the same boat looking for my first rifle - it's a common question! I'm gonna go with a 7mm-08 Rem or .270 Win depending if I can get a good deal on a rifle I like in either caliber.
BTW, GunBlue490 released a great video on the .270 Win recently:

He's also a fan of the 7mm-08. I'm in Southern Ontario too but I can see myself going after elk and or moose sooner than I can see myself chasing small game so not too worried by that .275 inch rule.

I wonder how many people understand the difference between cartridge and caliber; "cartridge" refers to name, "caliber" refers to measurement. A rifle chambered for the .270 Winchester cartridge requires a .277" caliber bullet in order to seal the gases behind it, thus the rifle's caliber is greater than .275". Since there is not now, any commercial .275 cartridge, the legislation must refer to measurement. The .275 Rigby, the Brit name for the 7X57, actually fires a .284" bullet, so could it be argued that the legislation was meant to allow the use of 7mm rifles?

The wording, and subsequent interpretation by the fish cops around that legislation is muddy enough that I think I'd avoid the chance of having an expensive rifle seized, and the possibility of facing sanctions under the wildlife act, by simply choosing some flavor of 6.5. While I'm sure a judge would consider the cartridge designation printed on a box of ammunition, the head stamp on a cartridge, or the cartridge designation on the rifle, as the basis for his decision, rather than a physical measure of the bore, but you can't be sure. It is also possible that the COs down there understand that .270 rifles would be commonly used for things like shooting coyotes, and wouldn't even consider charging someone for doing so with a .270, but its a gamble.

In my area wmu 95 thru 92 itswell understood a 270 is legal as they go by the barrelstamp. If the rollmark is 275 or smaller youre legal. If it starts with a 7 or any number greater than 275 youre in trouble. Alot of coyote hunters here use 270 rifles. The smart ones use varmint bullets but there's always idiots firing 150gr bullets across open frozen fields with no regard to where the bullet will stop
 
Actually Boomer caliber is bore diameter thus the 270 is 270 caliber. the 30 caliber rifles use .308" diameter bullets.

Can't you guys change that stupid .275 law?

A .270 is good but a levergun in .357mag is not? Someone needs to give thier heads a shake.

This ^^^ in regards to caliber. All about the barrel stamp.
 
Been living abroad for many decades
I have used 6.5 swede on literally everything if placed correctly.
Of course not as popular here but really try it and hope it will educate young shooters
Very very few occasions it has let me down

You think legislators and bureaucrats actually listen to logic or their constituents?

Ontario is full of rules/regulations that make no sense whatsoever.
 
This rule was bought out for a reason. As explained to me in the heavily populated counties in southern Ontario there were issues with ricochets Usually mil surplus shooting surplus ammunition. 303 was the main problem. The ban over 275 caliber was it included the full metal jacket slurplus rifles with ammunition readily available. From the 7mm up to 8mm. I don't know why they excluded 6.5 but the 6.5 x 55 was very uncommon at that point I guess. It was a safety concern at the time that has not been reviewed since.

So .275 Rigby is fine? A name is only a name, not a measurement. But if .275 is the measurement they intend to go by, that would be the unrifled bore diameter of a 7mm, which then makes the 7mm legal.

Thats correct , if stopped and your gun says .275 on the barrel you are ok, law says you can use .275 cal or under.
7mm they would convert and you would be over, 7mm converts to .276

Nah.


It’s still perfectly legal to hunt with Full Metal Jacket ammo in Ontario. If that were the concern, then that would have been banned as well.

And when it comes to ricochets, a 270 carries much more energy and lethal range than a 45/70 or a 9mm carbine.
 
If you are happy to shoot 7mm then hard to beat a 7x64

You can loaded projectiles for long range, you can load heavy blunt ones for in the bush and you can load a 120 or 130gr for fast, flat varmint shooting.

For truly under .275" a 6.5x55 Swede is very useful and my personal favourite a 257 Roberts as does just that bit more than a .243W
