It will be interesting to see what the BCs are. These could be good for matches and hunting.

 

[HighUintas]

I want to see what happens with a 220tmk out of a 300 rum or similar. But not shoot it.

 

[AZ_Hunter]

Cool. Now we need a SAAMI’ed 25 PRC type cartridge or 25-06AI or something besides the 25 CM to use these nice new 25 cal bullets. I’ve done wildcatting and don’t really want to do it anymore.

 

[RockAndSage]

Those 88 TMKs would be of notable interest to me in a .22 Creedmoor. And the 25cal 134ish TMKs out of a .25-06 AI.

Going on a mastodon hunt, I see...

 

[BreechFace]

107gr 6mm (243 WIN, 6ARC)
185gr 7mm (280AI)

Those are the two that interest me.

**** yeh 107 TMK

And another good option in .22 aside from the 88 ELD

Good stuff from sierra

 

[Q_Sertorius]

I’m excited at the prospect of the 133-135 grain .257 TMK.

 

[NWBLKTAIL]

Those 88 TMKs would be of notable interest to me in a .22 Creedmoor. And the 25cal 134ish TMKs out of a .25-06 AI.

I’d like to try those 133-35TMKs as well, just put an order in for a 257 wby barrel to repurpose a rifle I don’t shoot a lot anymore

 

[benconfused]

I'd be interested in that 107 TMK and how it compares to a 108 ELDM as a goto hunting bullet for my 6prc build. @hereinaz - what chu think?

 

[dreamingWest]

I'll be curious if any factory ammo loads these new bullets. Part of the appeal of modern cartridges (6.5 PRC, 6 CM, etc.) is to move me away from handloading.

 

[wind gypsy]

Heck yeah. Some interesting prospects there! I've got enough 6mm pills to serve hunting wants for a decade but the 107s could be awesome. The 107 SMKs seem to be a very forgiving bullet.

A non-AR length oriented 75-82 grain .224 TMK would be of interest to me for 223, 88 is getting pretty heavy!

 

[Treeman_MG]

I'm definitely interested in some 88gr .22's, 107 and 115 6mm's, and possibly the 153 6.5mm. Can't wait!

 

[TradLife406]

88 and 117

 

[Wrench]

They will probably make about 10k of each. Someone here will buy them, show results and drive the price to infinity.


And then we'll wait 2 years to try the magic pill which ends up being "pretty good ".

 

[vonb]

Looks like they are jonesing to keep up with Hornady. Now if they could keep up with Hornady on the price! I always liked Sierra better but their prices drive me to shoot more Hornady.

 

[43.6N]

So I guess the real question is which one are they going to sell out of first?

Hornady has been dog shit for about a year and half now, unfortunately.
