New TMK announced

[ResearchinStuff]

This has to be the biggest run of tmk I have seen. Hopefully a sign Sierra is seeing what people want

Except they forgot about the 77 gr.

trying to get Hornady 80gr ELD-M and ELD-X’s; and 88gr ELD-M’s to shoot at all in multiple 22cm’s. I have four of them, and both not one of them will consistently shoot those bullets without silly loads (like 2,700fps MV), and then only one.

This rifle/barrel has been bad with ELD-M and X. When I say bad- I mean average 5 round groups have been over 2 MOA. I’ve legitimately used up most of this barrel out trying to get it to shoot those bullets- 500+ rounds.

Whose barrel, and what twist?

Tikka 1/8”.

 

[nm.otter]

Rechambered .223 Tikka?

Reports from you and others here lead me to suspect that 1:7.5" might be the optimal twist for the caliber.

If the 107s shoot I’ll trade my 77 stash for them!

I might just abandon my 223 and run two dashers.

I finally got my 223 to shoot. With multiple kids I'm not giving it up

I understand. I was going to see if I could squeeze more consistency out of a 223ai but I’m at the point I might just use that money to buy more brass and bullets.

The dasher is like a 223 in recoil but it always shoots.

Hopefully Sierra can keep up with all these offerings.

So if we're going to compare these to ELDmx in the accuracy department, I have to ask...

I have shot 6.5 130 and 147 eldms and .284 180eldms and 284 162eldx and when I measure individual projectiles....ehhh, they're sort of all over the place, both within the same box and between boxes/lots.


The only TMK I've ever shot thus far is the .224/77 and I haven't bothered measuring them, ever, for any reason, except to see loaded rounds will fit a magazine.

You guys that have measured the overall length of the TMKs....are they pretty consistent? Moreso than the ELDs? I realize that with the newer offerings it may be too early to tell between lots, but just in general terms, how are they in terms of consistent lengths?

I measured 30 each when I got the test bullets:

Thank you!

Those are pretty tight numbers. I'm looking forward to trying some of them.

 

[Formidilosus]

22-250.

Yes. 1:8” works for most bullets, most places.

Out of curiosity to me learn something here, what do “bad” numbers look like?

Thanks for taking the time and posting things like this up

 

[nm.otter]

22-250

Thanks.

Clearly Sako's site is off -- still showing those in 1:14 twist.

They do two different twist rates in that caliber. Same with the .243s

@Formidilosus for a short barrel (14.5") 6.5 Creedmoor application for deer within a couple hundred yards in thick Eastern woods, do you think there is value in switching from the 130 TMK to the 153 TMK? I would happily make the switch if there was more potential for a quicker kill or even similar wound channel with a higher chance of the bullet exiting, but I wasn't sure if the relativity low velocity makes the 130 a better option.
