I think you did a great job on this. The firearm community is very warm and welcoming but not always forgiving of new writers. If you are looking to build your knowledge base I would be happy to recommend some sources to you. I like your honest style and I’d like to see you succeed.
Jill, the term ‘high velocity’ is relative like so many others in the firearm industry. If you can give an example with context I may be able to answer your questions or point you to someone smarter than myself. Otherwise, a mostly accurate rule of thumb is that speed rules. Even lightweight projectiles can deliver massive amounts of energy with enough velocity. Calibers, cartridges, projectiles and powder are all specifically designed to acheive a particular job. How much energy do you want / need at what distance? Should the projectile penetrate deeply through heavy muscle and bone against large game, should it disrupt violently and immediately to expend all of its energy on small bodied game or a mix so that it penetrates to the vitals of a two legged attacker without passing through him and endangering innocent people.

I have to say that this is a good, basic primer for beginners. A lot of shooters will nitpick and talk about possible / maybe and how this or that are wrong but this is a great article. Enough info to start conversations without overly technical detail. The only false bits are about shotguns. That is a weapon chock full ‘o smoke and myth and I’m sure that you’ll learn more before you do a write up on them. Keep the info coming and this site growing, I’ve really enjoyed the common sense approach y’all take.
Well reasoned and common sense based without being overly technical or dogmatic. Thank you for another great article.
