Absolutely not.
You should own several. Shorty for home or breach, stsndard for everyday, and heavy bull for long distance calls. At a minimum.
Ammo? Take your Costco forklift down to Cabelas. Duh.
From 300$ home build from cheapest parts I could find to 4000$ dollar elitist snob jobs like LaRue’s PredatOBR in 7.62 and Nemon Omen in 300 win mag that are scary accurate tools.
Great utility tools that are the all terrain vehicles of the firearms world IMO.
Were I chief cook and bottle washer of defense for this nation it would be quasi-mandatory for every adult 18 and older to OWN an maintain safely a minimum set of tools to include a AR in 5.56, a sidearm in 45 or 9mm, a shotgun in 12 or 20 gauge and a .22 caliber rifle or handgun with ammo for each as basics for defense and harvesting wild game for the freezer.
Just sayin ..... stay safe !
