95 TMK in 6 CM

43.5 gr H4350? Damn what are you guys shooting for brass & primers? I’m at 42 gr and 2900 out of a 16.5” barrel but didn’t want to step on it too much. I guess the ceiling might be a tad higher than I had thought. I have Peterson w cci 450s.

Starline and Peterson LRP Brass with Fed 210m
Lapua SRP brass with CCI450

Sierra has a max load of 43.1

How do you like the WRE primers?

Try different primers. I have three different rifles that hate those primers, and the exact same loads went from 2 MOA for ten rounds, to less than 1.5 MOA with CCI and Federal.

ok, will do; I have some CCI magnums and something else regular type here.

They go bang. Kinda tight to push in. I've shot a few thousand of them. I'm getting 1.5" MOA with most of my guns.

I switched to CCI 200 primers.

It's still a show over here.

I'm going to wait for a box of factory 108 ELD's to show up and shoot 10 before I pull the barrel and put on my PVA 1:7 barrel.

I noticed the TMK isn't that far into the case neck at the Sierra recommended length of 2.770".

45gr Staball, with the different primers and pushed to 2.680.



43.5gr H4350 with the different primers pushed to 2.680 and trickled.

That looks like something is widely wrong.

Some guns shoot them great, @Dioni A has had good service from them I believe. But in several of my guns the lot number that I have, hasn’t grouped well, and velocity ES has been really high- over 100fps.

I beat on everything and retorqued before that h4350 group.

Tempted to go ahead and pull it but I want to see what the 108 factory load does and then maybe some 112s to make sure it's not scrap metal.

I’m sure you’ve said it in here- what is the barrel?

PBB 16.25"

I thought it was 1:7.5 but it's 1:7.

They seem to shoot fine for me but I've definitely heard from others that some lots were erratic.

Man that is just bad. Those groups make it look like they aren’t stabilized. The TMK can be a bit finicky for really good precision, but nothing like that.
