Um...methinks you miss the point, which had nothing to do with reloading nor accuracy.
A 5.7mm round vs. grizzly will do little more than give him a very good reason to kill you.
Oh, and you’re not going to get enough rounds off to worry about reloading.
A 5n7 round is going to hurt arguably worse than the bite from a badger yet a badger can defend itself against a grizzly.
Never mentioned one round, you did. I stated the full clip. Go shot one. You’ll realize you can get a lot more rounds off than just one. It’s loud, but the recoil is almost zilch. GO SHOT IT, you’ll want to own it.
