Will Tikka come out with a 6 CM soon???

[TheM1DoesMyTalking]

With the new OEM Tikka barrel profiles that have the flare for factory threads, what is the best length to buy to have my smith cut to 16" or 18"? Does a 20" or 22" have more barrel OD (eg 0.725) to work with at 16" or 18"? Does the new profile taper smaller than the standard lite profile behind the flare or is it the same as before?

Can someone with a 20" measure how much it could be shortened without losing the ability to thread the bell?

It’s the same as before.

Not a gunsmith, but looking at it, I think 18” is doable. I would not bother though. I’d just get a shorter prefit and sell the 20” barrel if that’s the route I wanted to go.

Glad they made that law. Was gonna bring a 6.5 PRC but now I’ll grab a 6.8 SPC cause girth matters most

I actually took my 6.8 as a backup rifle on an elk hunt, once. In hindsight it was 100% up to the task of any shot presented to any hunter in that camp on that trip.

I have a 20" 6.5cm with the belled profile.

At 18" it measures larger than .67 but at 16" it is smaller. Don't have the calipers handy or I'd give you better numbers. IIRC the .67" cutoff point is like 17.3" or thereabouts.

My plan was to buy this 6cm and have the factory barrel cut to 16” and then have a shoulder added and threaded 5/8x24, are you saying the factory barrel is to thin to do this?

I'm not a gunsmith. I'm not even a carpenter, so anytime I throw out measurements, you should take them with a grain of salt.

Per my best measurements, if we assume that a 5/8x24 thread needs 5/8" of thread depth, which is what my Tikka 6.5cm has right now, then for an 18" barrel I'd want to slide back 2" from the existing barrel shoulder and measure. When I do that I get 0.69" which as I understand it is sufficient for threading 5/8x24 as most gunsmiths want .625"+0.050" for the shoulder, or 0.675" total. When I measure the same for a 16" barrel by moving back 4" from the existing shoulder, I get about .648".

Assume a straight-line taper of 0.021" per inch, you would drop below that .675" mark at right at 17.29"ish.

Put another way, the minimum length at which *my* barrel would keep a 0.050" shoulder on a 5/8x24" thread, is 17.3"ish.

Whether another gunsmith would try to thread the needle by going a bit shorter, I cannot say.

ETA: But I can absolutely say that I'd be 100% fine with a 17.3" tube. Or even 18". If I were spec'ing a custom barrel I'd do a contour that juuuuust let me keep the shoulder I needed at the length I wanted. But working with what's available.....ehhh, whatever. 17.x" is fine.

No. It’s not too thin to do that. Kampfeld or some other competent smith could still do that.

 

[Jbehredt]

Leave it 20” with an OG6S or cut to 18 with the hopes of a 5” ZG6 in the near future? Decisions decisions. This is what’s only mind at work today.

So, the t3x lite stainless will have a bell on the end of the barrel so it can be threaded?

 

[IrkedCitizen]

They are already threaded 5/8"×24tpi

If you’re trying to answer my question, I know come threaded. I’m asking if they have a belled out end on the barrel for that threading.

 

[nm.otter]

Anything Tikka/Sako with a D16 profile (Lite or Superlite) and 5/8"-24 factory threads has a belled end.

 

[IrkedCitizen]

Yes. They contoured the end of the barrel to be thicker for the 5/8/24 threads. Similar to mcgowen

Dang, that sucks. Maybe they’ll offer a non threaded version soon. Or better yet, offer it in a 6 GT.

 

[IrkedCitizen]

People have been asking them for years to thread them from factory. Now they are and people are upset that they are threaded. Lol

 

[TheViking]

I don't understand why this sucks? Leave the threaded cap on and go shoot. It affects absolutely nothing.

And if you ever sell it, I promise you it will be more desirable threaded than non.

Guessing you're gonna have to wait another decade on a tikka 6gt

 

[nm.otter]

You can always cut one down and add a shoulder bushing like before.

6mm GT has not even been CIP approved at this point. 6mm Creedmoor was approved 7 years ago.

I don’t want the stupid looking bell on the end of the barrel.
