So I have read the 130 TMK is a monster of a bullet. Sounds like something to build a rifle around.

Tikka Action with an 18” barrel and a suppressor. Max yardage will be up to 600.

What would you / have you built?

6.5 Creed, 260 Rem, 260 AI?

What velocity are you seeing and with what powder?

260AI.

Factory R700 Gen 2 action, barrel replaced and rechambered with a 24” Brux 7.5 twist. Shoots 147 ELDM @ 2955fps with very small groups.

I imagine that 130 TMKs would likely run around 3050 or so.

We are going to load up some 130 TMKs for my buddy’s 6.5CM which is a factory Begara with a 22” barrel. We are getting an average of 2730 with 143ELDX and H4350 powder. If figure we can get him into the 2800fps range with the 130TMK.
