The best bullet weight for 5.7×28 depends on your goal. Lighter bullets give flatter, faster shooting for target and varmint work, while heavier bullets carry more energy for larger game and wind. Match the bullet to the job and your barrel twist.
This guide covers how bullet weight and type change the way 5.7×28 performs, and how to choose for target, hunting or defense.
How bullet weight changes 5.7×28 performance
Within a caliber, lighter bullets generally leave the barrel faster and shoot flatter up close, while heavier bullets resist wind and retain energy downrange. Your barrel twist rate also decides which weights stabilize, so heavy for caliber bullets need a faster twist.
Bullet type matters as much as weight
Full metal jacket bullets are economical for target practice. Hollow points and soft points expand for defense and hunting. Bonded and controlled expansion bullets hold together on larger game. Pick the construction that fits the target.
Picking a 5.7×28 bullet for your use
For paper and plinking, a quality FMJ or plated bullet is hard to beat on cost. For deer sized game, a soft point or bonded bullet in a mid to heavy weight is a safe choice. Always build your loads from current published load data supplied by the powder and bullet makers, start at the low end, and work up while watching for pressure signs.

So what is the best bullet weight for 5.7×28?
There is no single answer, only the right weight for your purpose and barrel. Lighter for speed and target, heavier for energy and game, always within what your twist rate stabilizes.
The reloading process in plain steps
If you are new to this, the order of operations is simple once you see it. Inspect and clean your brass, resize each case and remove the spent primer, seat a fresh primer, drop a measured powder charge, seat the new bullet to the correct depth, and apply a crimp if your load calls for one. Each step has its own tool, and after a few sessions the rhythm becomes second nature. The single most important habit is to measure every powder charge and never rush.
What to watch out for
Watch for split necks, loose primer pockets, and any charge that does not match your data. Keep your work area clear, label everything, and never let a distraction interrupt the powder step. The reloaders who get the best results are simply the ones who are the most consistent.
