Sierra 88 TMK Load Data

[pods8 (Rugged Stitching)]

Shot some more 88’s today in the standard 8twist tikka 223 barrel, they continue to shoot well. Same load I’ve been using with H4895.

What COAL you at? Is yours standard throat or did it get throated longer?

Playing catch up here but 77s in my chamber as stuffed into the case, didn't know if these 88s have a profile that sits out longer?

Standard throat, nothing “optimal” about this setup.

COAL 2.460” puts me about .015–.020 off touch

They are stuffed deep into the case but I’m 200 bullets into this and they are really consistent

Did you try 77s prior in your chamber? Curious if your throat is similarly short but the 88s just are more elongated. 77s in mine need to be seated pretty close to sammi to fit my throat.

No iirc 2.330 was touch with 77’s in my chamber. Shot about 300 of those.

So you went from 2.33 with 77’s to 2.46 with the 88’s just from bullet shape?

Si senor, 88 is a long bullet

Noted, I got a shorty throat in comparison.

Got some N555 and N560 loaded up to test for my new 22cm with 88tmks. Have high hopes for the 560.

How did the N560 do?
