88 TMK Loading Thread

[rafiki]

Does anyone have a cut-away photo of the 88 TMK?

Also, does anyone have a suggested recipe for load/powder for running it in a Tikka with an 18" PBB barrel? I'm looking for something to start with that is the easy button.

which cartridge? everyone in this thread is working on the recipes...
i had light ejector marks on a brand new 16.25" PBB 22 creed yesterday with min 4831sc / staball hd loads so am going to run some more factory 80 elds thru it to get the round count up before revisiting

Every post of mine in this thread is with a Tikka and an 22 Creed 18" PBB barrel...

I'm trying to get to the same conclusion and I think the answer is generally yes. I'm at sea level and I'm concerned about that...

Same livin on the coast, but I ordered brass and 100 bullets. I’ll spin the barrel on, if it doesn’t work out there are plenty of guys on here who will use them.

Looks good... Assuming 1:8. Care to share your DA or Altitude?

Yes, 1:8 twist and DA of 4300'

I’m an idiot. 22CM

 

[rafiki]

any help/advice on diagnosing my issue or what you’d try next?

tikka 22cm
PBB 16.25” 1-7.5tw .120 FB (brand new)
rs1.2
scythe ti
DA 3,150 ft

first 6 rnds thru the barrel were factory 80 ELDX to zero scope avg 2,932 fps

load 1
-88 tmk
-43.5 gr stball hd
-peterson lrp (unfired)
-cci 200
-2.7 coal
-2,600fps

load 2
-88 tmk
-38.5 gr h4381sc
-peterson lrp (unfired)
-cci 200
-2.7 coal
-2,524 fps

only shot a couple rnds of each hand load bc i saw light ejector swipes and heavier bolt lift. shots were spaced out 1-2 minutes. bullets were seated to 30 thou jump in my chamber based on modified case and hornady oal gauge.
lots of new variables at play so not sure if i just need the barrel to break in more or if i should be looking at one specific element on the loads/rifle system.

Anyone shot them in an 8 twist barrel?

I couldn't get the 88 eldm's to shoot, but hoping these may work.

Ran in my 1-8 Tikka with no issues but COAL needs to be 2.4” min IME.

Understood, I'll be shooting them in a 22creed, so COAL shouldn't be a problem.
