100 Rounds of 40 Cal (S&W) For Sale

100 rounds of 40 S&W is the practical entry-level case quantity for the cartridge - enough for a focused range session or a couple of qualification drills without committing to bulk pricing. For 40 Cal shooters running a duty pistol or a personal carry gun, 100-round packs are the natural quantity for testing loads, topping off ready ammo, or stocking practice rounds alongside dedicated defensive loads.

40 S&W was born from the FBI's search for a service-pistol round that split the difference between 9mm capacity and .45 ACP terminal effect, and the cartridge still rides that compromise. 100-round packs from major manufacturers focus on FMJ training loads in 165 and 180 grain weights - the two factory standards that dominate the .40 ammo market.

Why buy 100 rounds of 40 S&W

• Single range day: covers a focused practice or qualification session.
• Per-round savings: better cost than 50-round retail boxes.
• Load testing: enough rounds to confirm a load runs reliably in your pistol.
• Storage-friendly: compact quantity that fits any range bag.
