Hey all. Wondering if anyone can drop a quick note about the differences in these muzzle velocities. I know there is a bit of difference but is it negligable or significant. My intended use would be range time, personal defense and poss hunting (at some point in the distant future). Thanks

Depends on the ammo but 100 to 150 fps difference on average
