Not quite. With a coyote license, the maximum is .225, but you can use any other smaller centrefire, including, .17 Remington or .204 Ruger for example. And with shotguns, the shot size has to be No.2 or larger.
We (the Newfoundland & Labrador Wildlife Federation) have been lobbying for more latitude in the calibers permitted, so that we are more like most of the other provinces, but its an uphill battle. Especially as some folks had (and continue to have, I expect) the rather flawed logic that if larger calibers were allowed, people would use them to poach big game. (Never mind that anyone inclined to poach will use whatever they have at hand).
As for the 'bounty', the $25 carcass reward is not technically a bounty, as the carcasses are being collected for science. There is a fair bit of resistance to increasing the reward, and I am doubtful that it would serve any real value in ultimately curtailing coyote populations in any event.
