New Bullets from Sierra in 2026

1

For the TMK crowd:

  • 22 cal 88gr - 100 pack (SKU 7188), 500 pack (SKU 7188C)

  • 6MM 107gr - 100 pack (SKU 7207), 500 pack (SKU 7207C)

  • 6MM 115-117gr* - 100 pack (SKU 7216), 500 pack (SKU 7216C)

  • 25 cal 133-135gr* - 100 pack (SKU 7334), 500 pack (SKU 7334C)

  • 6.5MM 153gr - 100 pack (SKU 7450), 500 pack (SKU 7450C)

  • 7MM 185gr - 100 pack (SKU 7685), 500 pack (SKU 7685C)

  • 30 cal 220gr - 100 pack (SKU 7720), 500 pack (SKU 7720C)

I can’t even imagine what a 220gr 30 cal TMK would do to an animal…excited for the 22, 6MM, and 25 offerings though!

Thanks for posting this. Hadn’t seen the announcement.

I was trying to hold off on a 25CM, but all of these new 25 cal bullet offerings may change my mind.

I’ve also heard there’s a new 25 cal chambering coming out soon.

Right!? I completely brushed off the 25 CM when it was first released, but now I’m second guessing myself. Do I stick with a 6 CM that is flatter shooting or go with a 25 CM and get the better wind drift….

What’s the new rumored 25 Cal? 25 BC?

Don’t know the specifics yet. It was mentioned on yesterday’s big game hunting podcast with John Mcadams. Richard Mann was the guest and he was saying he was involved with its development. It’s 25 caliber and it pushes 100 grain bullet roughly 3,400 feet per second.

Should hear the official announcement sometime next month. Probably at SHOT.

I myself was seriously considering a 22 Creedmoor. But now starting to wonder about the 25s

I’m betting that it’s a 25 PRC!

Was doing a Google search for new 25 chambering and ran upon another Outdoor Wire article about new Barnes factory ammo using the Sierra TGK.

7PRC, 7mm-08, and 6ARC.

Also subsonic loads for 300BO and 308 using Sierra bullets

I think Weatherby has a new 25 coming out soon, they have drop a few hints over the past year on there podcast.
