Pistol caliber Question

So a 9 mm, 40 s w and 45 acp is between the caliber specifications of .243 and .275?

I signed the petition, but not sure what good it will do.

If you're up north the regs allow you to use calibers over .275 for small game. In that case I go back to saying .40 s&w, .45 acp or 10 mm. I personally prefer a cast bullet for small game and a jsp or jhp for big game. The caliber restriction only applies in that area if you're hunting small game during a big game season and don't have a big game licence for that season. Even a 9mm with the right bullet is good enough for deer, and if you don't reload it's cheaper than the others. I hope that helps.

9 mm, .40 s&w and .45 acp are all appropriate and legal cartridges for small game and deer in the area of Ontario you are talking about, and they are all available in a JR Carbine. There is no pistol caliber "in between .243 and .275" in any practical sense. If that doesn't answer your question, then I'm sorry.

There are no big game cartridge length restrictions in Ontario?

It does help! I'm gonna research more Of these calibers and I to wonder if there is cartridge length restrictions for hunting in Ontario
 
Well obviously I'd do my own research after gaining advice from others but ur saying a 9mm handgun caliber is bigger then a .308 win ? :s

This must be the new math they were talking about, where 9mm (.355") is somehow between .243" and .275". I guess society needs garbage men and ditch diggers too.
 
.308 as in 7.62 mm

New math or old 7.62 <9mm

TJ you need to bone up on your basic ammo terminology.

Caliber refers to the diameter of a rifle or pistol barrels bore and the corresponding bullet. It can be expressed in fractions of an inch or mm.

Yea true, I didn't think that one thru lol I guess I assumed rifle calibers would be generally a larger diameter when compared to a hand gun caliber because hand guns are smaller. Well I'm back to being sorta confused...but I started off there so at least I'm not behind

You have to be a product of the public educational system?

9mm = .355" Is that bigger or smaller than .308"?

Understatement of the year!

I'm not to sure what the hunting regulations are in Ontario.
Where did you take your hunting course?
 
Well to be fair to TJ, the media constantly using terms like "high caliber" when referring to AR's doesn't really help.
 
You are going to make mistakes when learning something new. Now I know.
Ur insults don't phase me. I didn't convert 9mm and realize what you guys pointed out.

I took the hunter course in Barrie .
I looked at the Ontario regs and it doesn't specify caliber restrictions , just says must be centerfire for big game, unless I missed the specifics.
 
When I was just getting into shooting and hunting, I bought the book "Cartridges of the World". I found It helps put the somewhat complicated world of ammunition in perspective for the uninitiated, and can assist in choosing a caliber that is well suited for the job or jobs at hand. I'd suggest reading through at least the sections on shotgun shells, common rifle and pistol cartridges.

Too bad the education system didn't teach you empathy, respect and common courtesy. Those are qualities I hold higher then being able to covert measurements.
Maybe you were to busy making fun of someone else during tht lesson in grade school? I recommend u go back and complete grade school again, because those qualities I listed will be needed more frequently in life then measurement conversion.
 
TJ, you are getting pretty good responses considering how strange your question was.
It's hard to believe that people can pass the CFC gun courses without understanding some of the common terminology around ammo.
 
Hey TJ. There's a few on here that are being unnecessarily rude, but for the most part, you gotta take your licks where licks are due. The caliber differences that confounded you are clearly covered in the PAL course book, so I can understand some folks SMH response.

Anyway, moving forward, here's a few resources for your future use:


Here's a link to a variety of common pistol and rifle cartridges, and their respective diameter in inches:

Here's a pic of some of those for comparison's sake:


Hope it's not too blurry :-/

Alternatively, you can also just take any caliber in "mm" and multiply it by .03937 to get the caliber in inches. Conversely, you can take any caliber in inches, and divide by .03937 to get the caliber in mm. I should note though, that these are approximates. Cartridge calibers are names, not diameters. Yes, they'll be close, but bullet diameters don't always line up with their cartridge names. For instance, your .308, if measured, will actually be closer to .311 (if I'm wrong, the reloaded a will be by shortly to correct me). It's not a big difference, but something to be aware of anyway.

Lastly, here's a (very) simplified chart of what cartridges suit which game. I post this at my own peril as there are thousands of threads on here arguing about the suitability of caliber X for game X. It's a loose guideline at best, but a place to start nonetheless.



I hope that helps a bit.

Ps. A lot of folks (myself included) set a "kinetic energy delivered at range" threshold for themselves. That is, they pick a number of foot pounds or joules as their ethical limit for for a certain type of game. For instance, my self-imposed limitation is 1000ftlbs for all large game (save grizzly). Kinetic energy depletes rapidly as a bullet travels down range, so I set my maximum range limit at the point my bullet's kinetic energy drops below 1000ftlbs (or where my accuracy drops off, whichever's shorter). So with something like an SKS, I wouldn't shoot game past 125 yards. With something like a .300 mag, it's kinetic range far out reaches my accuracy range so it's my own competence with the rifle that sets the range limit. When it comes to handgun calibers, there's not much that meets my limits. Not to say that a 10mm carbine like this beauty wouldn't fit the bill http://www.canadiangunnutz.com/forum/showthread.php/1375502-10mm-Takedown-Carbines! but that's up to each individual Hunter.

Pps. Spend a little extra time in the hunting regs if you're looking to get a pistol cal carbine. Many come with 10 round pistol mags (legal) but if you province's hunting regs specifically limit "centrefire rifles" to 5 round magazines, then you'd need to abide by that when hunting to keep yourself out of hot water.

Cheers.
 
Do it right or not at all ... I wouldn't hunt yotes with 9mm, I would buy the proper caliber for it.

Honestly I wouldn't worry about buying another gun when you got a 308 that you don't use. Sorry if you going to keep on asking questions and not use what you got or shoot, your going to get the negative that you are getting.
 
I have friends in the US that use their .357Mag lever guns on deer with good results. Inside of 100 yards the cartridge has enough power to deal with both deer and coyotes at that range. The 44 mag in a lever gun would certainly be enough.

Take Care

I do like the action of a lever gun as well! They are one of my
Favorite to use . Hmm..

First time I go up the cottage I'm going to bring my 308 and try it out. I'm itching to try it.

I just want an affordable* AR style rifle and I'm trying to figure out if the JR carbine, which only comes in handgun calibers, is what I should focus on..
