Misc What’s the largest caliber rifle that’s available in the open market?
I was scrolling through Reddit earlier and came across a historical post featuring a Boys anti-tank rifle. It got me wondering:
What's the largest caliber rifle you personally own?
And out of curiosity, what's the largest caliber rifle that's currently available on the market?
Looking forward to seeing everyone's answers and maybe a few pictures too.
Cheers

It's going to be some Mauser pattern bolt action chambered in an obscure magnum caliber that's less than 9000 joules.

10,000J and under and still good. A few skirt the limit.

Safari rounds under 10,000 joules are the biggest legally allowed ones. For example
375 H&H
500 nitro express
There are a bunch at 450 and 460 but I’m not a safari dude.
More common “big” rounds are 45-70 for hunting and 338LM for long distance shooting (though folks favour smaller rounds these days like 7mm PRC.
My biggest is a 325wsm lever

500 Jeffery and 375 Enablr come closest to the limit.
577 Nitro Express falls under the limit.

Ngl something called a Jeffery doesn’t sound scary, but it would probably separate my spine

I know 338 lapua is still allowed. All the big calibers got banned as falsely being interpreted as ‘anti-material’

I mean….the 50bmgs kinda were….(not that I agree with any of the bans)

Damn… I never got to fire the one at silverdales

I really wanted a GM6 Lynx or Cadex Tremor

I wanted the lynx for years. Then I saw a YouTube review (I think Brandon Herrera) who showed the gun was sub standard. Poor accuracy and feed issues. Kinda glad I didn't sink those massive dollars on a mediocre gun that is a paperweight now

I got a chance to fire one on Canada Day at my local range before the ban. I was grinning like a fool

Largest caliber or energy?

Get a .577 Nitro Express. They’re still legal, apparently.

I saw a video of some dude in the states with a P40, with all 6 .50cals in service.
What a life that would be!
Honestly, I probably couldn’t even afford the ammo

u/hafetysazard Aug 01 '26
I think .577 ammo in Canada would push $400/ a box

Hell new Federal 470NE and 500NE already pushes $400 per box.

I looked up a .500 Jeffery I saw used the other day and that’s getting over 9000 joules if you load it up.
Why wouldn’t you?
Also, possibly why it was available used. Someone probably took it out one time or on safari or something and said never again.

u/ShadowcastZ Aug 01 '26
375 enabelr, it's 9600 joules. Anybody that says otherwise doesn't know what they're talking about.

I think technically you could still but a 50BMG. Aslong as the barrel was short enough to he under the Joule limit?

u/GodsGiftToWrenching Aug 01 '26
Biggest caliber? Probably .577 enfield or something else in .577, there may be something with an even bigger bore, which if you recall from the CFSP that caliber is indeed the size of the projectile not the power related to the round

u/_Pray_To_RNGesus_ Aug 02 '26
Technically, there isn't a limit as long as it's an antique. Someone posted about getting an antique 4 bore a while ago.

I have (had) a WB Mk 5 safari Classic...in 460 WM. I contacted them ( Weatherby) and bought a new barrel in .378, so i get to keep my rifle now as its no longer " Above 10k joules" .

.577 Nitro Express. 49 grams of lead, 9500 Joules of energy. Immeasurable awesomeness.
Isn't she beautiful? I am even getting turned on by its shape.

378 Weatherby brings you up there as well as the cartridges based on it. 338-378 and 300-378. The 378 necked up to the .460 Weatherby it becomes illegal over 10k joules.
It's freaking silly tho never heard of a crime committed with a Weatherby super magnum.
Oh if it's ignited by flint or match it qualifies as antique and there's no limit. Pirate cannons are a-ok.
