Question 1

What is the difference between .223 Remington and 5.56 NATO FMJ?

Accepted Answer

.223 Remington is loaded to lower chamber pressure than 5.56 NATO. Performance is similar in rifles with 5.56 or .223 Wylde chambers. True .223-only chambers should avoid 5.56 ammunition. Price is typically identical between the two.

Question 2

How much does .223 FMJ ammo cost?

Accepted Answer

.223 Remington FMJ runs $0.28–0.45/rd for brass-cased loads. Federal American Eagle, PMC Bronze, and Winchester White Box are common options. Pricing is essentially the same as 5.56 NATO FMJ from the same manufacturers.

Question 3

Is .223 FMJ good for varmint hunting?

Accepted Answer

FMJ .223 is not ideal for varmint hunting — the full metal jacket may not expand reliably on small targets. Dedicated varmint loads with V-MAX, Ballistic Tip, or hollow point bullets are more effective and produce rapid expansion at .223 velocities.
