Depends on what your firearm "likes", In this instance (pug), it probably doesnt matter, as the barrel is so short, and the distances you would be trying to use it is not feasibly very far... so the "hottest" round would be my personal choice here...
However, my Marlin 22 Mag rifle HATES the Winchester ammo, wont shoot anything smaller than 10 inch groups with it at 100 yds, but ALL other ammo I have tried in it shoots no larger than 1 inch groups at 100 yds.... (when I do my part)
Leave me alone... and I will leave you alone....
Don't poke a wolverine with a sharp stick unless you want your balls ripped off.
Don't start nuthin, wont be nuthin.....
