Just got order notification on .25 cal TMK’s so they should start being run soon!

I might have missed it…what did Sierra land on as far as a final bullet for the quarter bores?

135gr

Sniped some 185gr TMK's from Precision reloading. I really don't enjoy shooting my 7PRC but with this bullet I just can't escape it. OIL elk tag for me this year so I think I'm going to give 'em hell with the green goblins...

If anyone has pet loads for 7PRC and 185gr TMK's let me know. I'm thinking RL23, N565, H1000 or maybe Retumbo.

Man, I've been trying to find some of the 185's. Does anyone know of anywhere else they are in stock?

Could you measure a few 185s and post the bullet length?

Anyone seen a BC number on these?

Damn I would have guessed higher

 

[KY_coop]

Not terrible but not great. Did they happen to say when the 25's would hit shelves?

 

[IrkedCitizen]

I don't think TMK or Sierra bullets in general have ever really chased high B.C.?

 

[KyleR1985]

I’m hopeful they track the 22 cal 88’s. Lower BC than you’d expect or want but seem to shoot lights out with no fuss.

For what it’s worth, the 6mm 107s trued up closer to .600 for me, but a lot of that may be my extremely high DA.

Has anyone shot the 153's in a 6.5 creed?

I’m putting some together right now. Anything specific you want to know?
I’ll get chrono data tomorrow out of a 24” and 18” barrel.

Just curious on what your speeds are. Also, if they seem picky/finicky.

Copy that.
