We aren't referring to the OP's original question. We are referring to your question "So will you adapt when somebody decides 5 is too many?"
Just to clarify.
Ok, I was probably too short on my posts, let me explain a bit.
When bill C-68 came out, the Liberals saw a need for competitors to be allowed higher capacity magazines. At that time, they even told us, "don't worry guys, this isn't about you." So, the exemption was put in the bill so competitors (mostly IPSC at that time) would still be able to keep and use whatever magazines they needed.
At the same time, IPSC shooters began pinning their mags to 10. Even though the exemption was there, to my knowledge, they never issued any permits. IPSC Canada actually put a rule in place saying that anyone using a magazine with over 10 shots would be disqualified from the match. Now this is probably 20 years ago so I don't remember exactly, but I think Kim Campbell became PM and too the exemption out because there was no need for is since IPSC already had a 10 shot rule. Feel free to correct me if this isn't accurate.
So, for shooting a club match with 15 or 20 guys, you can use single shots if you have to but if you want to compete on a world stage, forget it. With an IPSC gun, there is a big weight difference between 10 shots and 30 shots, the gun recoils different. Reloading a 23 shot mag into the gun is different that reloading a 10 shot mag. Stage strategy is not the same either and you can't practice this stuff without the same equipment.
3 gun shooting is even worse. AR mags would have the same issues as above, but then we have shotguns. You can use 8 shot speed loaders because your tube only holds 5. Sure you can change tubes when you go to the US, but again, the gun feels different and your speed loaders are different lengths. That's why I don't shoot international 3 gun events, there is no way to properly train for them.
Now I'm not saying you can't still have fun going to big matches, maybe you can win a high C class trophy or something, but there is no way you will ever win the match.
When you guys say you can adapt whatever they throw at you, that's fine for a club shooter. But if you want to shoot world class events, you won't be able to compete with the guys that shoot this equipment every week or every day. That's why the message to the government should be, "you are killing our shooting sports in Canada and embarrassing our international competitors."
