Description

Sierra 30cal 110gr Round Nose Carbine #2100

These rifle bullets were developed specifically for use in the 30 M1 Carbine. The 110 grain Roundnose #2100 bullet has a soft point that expands consistently at carbine velocities. For small game, this bullet can be used in all 30 caliber cartridges (at reduced velocities). These bullets are best suited for close-range varmints or informal target shooting in handguns of 30 caliber.

Best Suited For

This projectile is ideal for:

  • .30 Carbine shooters (especially M1 Carbine platforms)
  • Small game and pest control
  • Reloaders wanting reliable feeding in semi-auto rifles
  • Reduced-load shooting in .308 Win / .30-06 (light loads only)

When To Use It

Use the #2100 when:

  • Loading for .30 Carbine rifles (primary use case)
  • You need smooth feeding from magazines (round nose design)
  • Shooting at short to moderate ranges (~0–150m)
  • Developing low recoil / reduced velocity loads in larger .30 cal cartridges

This bullet is not intended for high-velocity magnum use—it performs best at moderate speeds where expansion is reliable.

FAQs

Q: What is this bullet designed for?
Primarily the .30 M1 Carbine, where round nose bullets ensure reliable cycling and feeding.

Q: Can it be used in .308 or .30-06?
Yes, but typically for reduced loads or small game—not ideal for full-power hunting loads.

Q: Why round nose instead of spitzer?
Round nose bullets feed better in semi-auto carbines and are optimized for shorter ranges.

Q: Is it good for hunting?
Yes, for small game and varmints. It is not intended for large game.

Q: Real-world feeding reliability?
Community experience consistently notes that round nose bullets feed best in M1 Carbines, with other shapes sometimes causing issues:

“Anything but a round nose… will rarely feed reliably”
