Misc Quick questions
A couple of random questions:
- if you buy a used gun that you can’t physically inspect how likely is it that the barrel has been “shot out” and is less accurate? Does the calibre affect this (is it more likely to happen with a .308 than a .223 because of the higher pressure - or does the added cost of .308 ammo mean it is less likely that a high shot count was run through the gun)?
- In terms of sheer numbers, what do you think are the most common types of centrefire ammo in circulation within Canada. I am thinking .223, then 7.62x39, then maybe.308…? Ultimately I’d like to get a reliable bolt in each of the most common calibres.

Ask for pictures of the rifling.
Unless the person was doing competition or you buying used old surplus firearms (excluding most Chinese SKS/French Tickler), chances of barrel being shot out is not high. Watch out for rust/pitting in the barrel.
Ammo is expensive to shoot. You won’t be sending thousands of 308s down the range, or even 223 (excluding 3-gun back when stuff weren’t banned)
Any modular platform like AR, you can swap out the barrel. Too bad ARs are banned.
Most common centre fire ammo: 9mm
