95 TMK in 6 CM

[ID_Matt]

I think there is a thread or 2 about them in the 243, but don't know I have seen one for the 6 CM. I am sure there is a handful of us that got a few boxes with the last run sierra did... who has tested them in the creed yet?? Assume H4350 is going to be the go to powder. TMK's don't seem to be too picky to seating depth. What are we loading and how fast in what barrel length??

I’m using 43.5gr H4350 for 3,135fps MV, 18” barrel.

My tikka is getting a new 6cm barrel right now. I’m going to start with R16 and H4350. I’m hoping to get around 2900 with a 16.5 barrel. @Formidilosus what is your COAL on those?

SWEET. I was using 3,000 in my calculator and getting about 700-800 max distance using 1800 FPS. 3100 would sure bump that safety margin up.

BC of 0.238 close enough?

2.680” coal

Everything I have done with the 95gr TMK- four different barrels/rifles and out to 980 yards- has shown a .500 G1 BC.

I’m using 43.5gr H4350 for 3,135fps MV, 18” barrel.

I just put my PBB 16.25" barrel on and loaded this load to 2.680 and I'm hovering around 2975fps with 60 rounds on the barrel.

I made the brass from Hornady 6.5cm so I'm fireforming a wee bit in addition to seasoning the barrel.

DA is around 200 today.

What twist do you have on your PBB?

What twist do you have on your PBB?

1: 7.5

I have a second barrel sitting too that's 1:7 that is supposedly a nicer barrel.

I'm going to beat on this PBB with pressure as a test barrel and switch over after I figure out this load and I'm going to make a slower load with H1000 or Staball HD to meet Quick Drop around 2775fps.

I'll take that light load hunting with my wife in 6mm minimum states and we can share the gun. My goal is to reduce recoil and calculate her drops in my head.

I’ve got a 18” 1:7 waiting to put on my action after the season. Haven’t seen much on the 1:7

Mine is 18" too.

Lot to be said for the quick drops. When my 6CM MRC arrives the plan is to match load it to the Tikka PBB 6CM (1:7 flutted from @hereinaz, shoots lights out w 109s), so I can have same elevation and wind calls for wife/kid/randos.

I need to step on the 95 TMK a bit, getting 2900fps at 41.5 gr, but recoil is nice and light.

Not pictured is the 95TMK (2.770 COAL ? , whatever Sierra book was). It was 1.2” for 10.

Yeah, the nice thing about all these long chambers that are popular is you can crank it out and fill it up with H1000.
