Crosman 1377 & 1322

The current rule is <500fps AND less than 5.7joules muzzle energy. If the 9gr pellet is coming out of there fast enough to go above the Joules limit, then you have a problem, but check with a chrony and run the numbers before you panic and detune. Usually the lightweight silly pellets (which no serious shooter would use anyway because they're awful for accuracy) stay below the muzzle energy requirement. This calculator helps for plugging in your numbers:

Your wording is confusing.

from the RCMP website , to be consider a firearm you need both a high muzzle velocity (greater than 152.4 metres or 500 feet per second) and a high muzzle energy (greater than 5.7 joules or 4.2 foot-pounds) .

So you can't exeed both limits.

EX: 800fps and 3joules = non firearm
440fps and 18joules = non firearm
520fps and 6joules = firearm / non restricted rifle / restricted handgun !!!!

thanks for the calculator
 
Not sure what part of my wording is confusing... You've restated what I wrote, but using 'higher than' to be considered equivalent to a firearm, where I posted 'lower than' numbers for staying below the level which is considered a firearm. Two ways of saying the same thing.

Your examples go on to illustrate three possible sets of numbers with classifications resulting, and I believe this is where things become confusing for a lot of people. Not because of the explanations attempted in forums. Rather it's because the rules themselves are puzzling. For example, so far as I understand the rules as they stand now, example #2 is correct, and could result from shooting a 30gr projectile at 440fps, such as could be the case with a lightweight .30" pellet out of an air pistol with relatively low pressure. That's a fair bit of energy, certainly a LOT more than a sub-PAL Canadian Tire air rifle delivers, more than triple in fact, and yet this strangely constructed rule seems to allow it. That's the confusing part, as far as I'm concerned. There is no magical property of big bore airguns which makes them somehow less dangerous than .177" or .22", but the RCMP 'experts' seem to think there is. It's strange that they don't simply use muzzle energy as they do in Germany or England.
 
Yes the rules are confusing a bit but extremely stupid.

The most lethal and concellable "non firearm" airgun would be a stubby handgun in a large bore caliber. ( under 500 and lots of energy ) The opposite is just silly and non lethal....

....... And I wonder where the 5.7 joules come from !!!!!!

you could build a non firearm .45cal pistol shooting 180g bullet @ 400 fps !!! considered non firearm
 
Ive had a few but not in 10 years. I would rather just work the lever once on my 22 HW45 then pump a bunch or buy co2 for that matter. If you go for one .22 for sure, it rocks the cans a lot more than 177. They are nice little guns for the money though, especially with the shoulder stock they make for a handy little carbine.

P1377 with steel breech, backpacker stock, reworked trigger 2.5#, shoe, mirror polished hammer,
18" barrel and a Bushnell 3-9x32 AO scope.
1377 for critters smaller than squirrels....
1322 for squirrels and rabbits etc....

For those shooting grouse with them, is it head shots only? Also when you pump it ten times how long is it ok to leave like that and still have acceptable velocity? I have 2 1377's and thinking about taking one moose hunting this fall for chickens.

The Crosman barrels are all 7/16" what fits the pumpers fits the 2240.A flat top piston and or a longer barrel will boost velocities you can cap at just under 500 fps. I'm having a 2289 14" barrel done and have a custom 2240 with 10 " barrel that is lights out on chickens at 20 yards head shots are easy.Shoulder stocked into a carbine 495 fps with a 14.3gr pellet.Steel breech added to both for strength and scope mounting topped with a 4x Banner 1" Lothar Walther makes a match .177 barrel in 10" length if accuracy is paramount.D+L airgun in BC has barrels.

Well you just cost me $100. Bought a steel breach and a butt stock for the 1377.

make sure you can hunt with a pistol in SK
in BC we're not allowed to (1377/1322 are pistols regardless of the bbl length)
as such I rebuilt a 2289 which was sold as a rifle and I'm good to go.
for some reason the chrony won't register the crosman 14.3 pellets reliably but I assume it is under 500fps. Even if they're not, I have a licence.
just don't know what the transportation regs are (I can't easily pull an unused pellet out of the breech)

as for grouse, go for head shots if you can
I used my 2289 on crows and at 10yds one died before it touched the ground while 2 others needed the use of the backup shotgun. The pellet didn't go in very far.
 
I am having a 2289 done up with a new steel breach, Blue Fork barrel band,custom brass flat top piston and a switched out 2240 hammer spring.From what others that have done to this the gun will not excede 500fps no matter how many times it's pumped.The idea of the pump is it will not be effected with cold like the C02. I have a custom 2240/10" steel breach,shoulder stocked with a velocity adjuster set ,4x Banner and locked at 495 fps with 14.3gr Crosman domes.Head shot quite a few grouse.The 2289 may be considered a pistol as the stock is easily removable and can be fired with one hand.Stupid I know but so are the gun laws.

Got the P1322 last year on amazon for around 110 to my door. Kit included the pistol with peepsight, 175 pack of Crossman pellets, black carbine stock and an unmentioned tactical pellet holder pouch ;) bought a steel breach which costed me almost as much as the gun itself. Threw on an old Crapco 4x scope I had laying around. Thing shoots fantastic groups at 15m. Ran it through a chronograph, averaged around 480fps with Crosman Domes. I love it and have plans to tinker with the trigger and put on a slightly longer barrel. But every time I think of working on it I end up going out and shooting it instead. They're a tinkeres dream. If you don't want to turn one into a project is suggest biting the bullet and putting on the steel breach, I've been thrilled with mine since.
 
Old thread but if you want to build a legal (non-restricted) rifle based on the 2240 you can do so using the main tube from a 2260 which is available as a sperate part. No more 2240 main tube means no more pistol classification, it is now a rifle.
 
I have an old 2260 I converted for high pressure air instead of CO2 bulbs. Put in an aluminum pass-through block and drilled/threaded a taper thread for a pressure gauge. Made an SSG (externally adjustable hammer striker) and carved away a lot of hammer weight, tuned the valve, eventually arriving at a very consistent 25 shots at 13.8fpe with JSB 18gr pellets, max fill pressure of 1200psi and dropping to 500psi when velocity starts to drop rapidly. Efficiency with this tune is 1.94fpe/ci, so efficient that it sounds like 2 pumps of a 1377. Amazing gun to mod if you do your research and do good work on the parts. Bob Sterne is the master in this regard and his posts are on many forums, as he understands forums come and go, and wants his contributions to remain online somewhere for the longer term.

Nice custom 2260! I might end up there but I'm only just starting to mess with these and I'm still on 12g CO2 for now.

Probably a safer bet if you don't have some decent machining skills. Leaks are the bane of the Crosman modder. So easy to have just about anything leak. At least with CO2 you're limiting the number of locations where that can happen. But for me it was totally worth the effort as that gun gets so many shots downrange with decent accuracy with so little pumping effort. Getting it up to 1200psi seems almost like cheating, just so easy compared to my Brocock Atomic for instance, which functions best when pumped to about 2,700psi, or my HPA-converted, regulated bottle fed Industry Brand QB78D, which needs about 250 pumps from the FX pump to bring the 213cc bottle to 3,000psi. Of course that gun puts out about 130 shots at 21fpe for the effort... but still, it's a lot harder than using the 2260. And the 2260 is a heck of a lot cheaper to operate than with CO2, as well as delivering a very much flatter shot string than CO2 beginning to end of the 25 shots. CO2 is much more of a peak, meaning accuracy beyond 10 yards becomes a matter of guessing where I'm shooting in a CO2 bulb's short lifespan.
