95 TMK in 6 CM

[KyleR1985]

Neither my 6 Creedmoor (16.5 inch PVA barrel) nor 243 (Tikka barrel cut to 17 inches) like these.

6 Creed is 2.89 MOA for 30. I shot 10 at a different target and the groop was so bad I shifted to another bull. This is a compost of the 10 and 20 round groups.

243 is 2.14 MOA for 33 rounds. Shot 7 is a compost as I aimed at the wrong bull.

It is not an inherent problem with the rifles.

This is the 6 creed today with 112 MBs and 108 ELDMs.

This is the 243 with 108 ELDMs for about 2 weeks ago.

Edit: The 6 Creed can was loose and I shot the TMKs last. I'll try them once more with a different powder or charge just to confirm.

COAL?

Freebore?

Velocity?

Mostly interested in 6cm, but would like to know both.

My 6 Creed doesn't like the 95's either, I have a remaining box of 80 if anyone wants them send me a PM and I'll give a Rokslide discount.

I suspect you are chasing your tail with the 95's. I lost interest in screwing with them, just not worth it when others fly so nicely.

I think you are probably correct.

COAL?

6 creed is seated with boat tail at neck/shoulder junction. 2.647"

Didn't measure on the 243, but can go back and measure.

Freebore?

6 creed is PVA standard, which I believe is longer than SAAMI.

243 is Tikka factory, and not all that long as I have to seat rounds deeper than the neck/shoulder junction.

Velocity?

6 creed was 3000 average for that 30 rounds. I was slightly below book max and had heave bolt lift on 4/30. (Side note, heavy bolt lift is significantly more obvious on the creed, with the 243 I could have bad ejector marks and not notice much on the bolt).

243 is averaging 2890 over 94 rounds. No signs of pressure.



I loaded up 10 of the 95 TMKs last night with 43.5 gr N160 and backed off the seating stem 1 turn (COAL 2.689"). I'm not expecting much, but figured might as well see.

I’ve played this game. Either the barrel likes them or it doesn’t. Don’t bother changing powders/charges/primers/etc.

Was going to sell the 95s that I had, but gave them a shot in a different barrel and they are like 10 in 1.3”

 

[KyleR1985]

It’s got to be freebore with the 6 creeds.

The 95’s shoot great in 6x45, 6ARC, 6 dasher.

I got them to shoot 1” for 5 at .070” off lands of a cheap outlier 1:7 16” 6 creed barrel. But it was with 37gr varget 2850fps avg. that was COAL 2.745” which is about as long as you can load them. But I never messed with that barrel again after.


I don’t see any reason why the 243’s wouldn’t like them though.
