The slow barrel tikka dilemma

[Brandon_SPC]

That extra space is more room for powder or pressure anyhow. You might be able to make them extra fast, especially if you fireform, necksize, and load. That's what I'm trying with my new 223ai barrel. The trick of course is assuring good extraction when you need a backup shot...

People still neck size? I always fill length size and only bump the shoulders back .003.

Yes, we still neck size. I neck size new brass until it starts to get tight in the chamber…then I start full length sizing for remaining life of the brass.

Tried handloading for the 156? I was spanking those out at 3k and change with a 24" and a Berger max charge of 570.

I don't have much experience with oem tikka barrels. But my 223 is doing 2830 with 77 tmks and a max charge of n140. Which seems pretty dang good. Barrel is still new too.

Easy button for more speed over the 6.5 is going to the 6 UM or a faster round. Why I sold my 6.5 for a 6 UM. Shorter barrel but still getting over 3k. Ok easy, but not very cost efficient

My preference is to keep 1800fps to 1000yds for my application and environmentals for this rifle in particular.

Which is what? Shooting animals or targets at 1000 yards?

All of my tikka barrels have been a touch slow, none of them sped up and made that ground back reloading.

Ive just tossed it up to the price you pay for easy cheap accurate and long lasting takeoffs. Its not worth 500$ more for 50-100 fps for a custom barrel to me for anything aside from my comp gun

My 24” PRC is 2795 with factory 147
My 16” creed is 2600 with a 130tmk with the same load people on here claim 2700
I had a 20” ctr that was like 2550 with factory 147s

Targets mostly, but the retained velocity to 1K for hunting is a personal preference for this rifle.

I have one batch of reloads running 147s over 56.5gr of retumbo that’s giving me 2780fps. It’s about 2gr under max I believe. Once my next batch of brass is shot I’ll try bumping it up. And maybe try and find some N565- it looks like guys have been having luck with that

I’m not saying your tikka isn’t slow but hornady factory loads are always way slower than advertised. Even out of a 24-26” barrel I rarely get within 50-100fps of advertised. The only factory ammo I’ve shot that is consistently close to published is federal.

That sounds pretty decent. As long as you get your max yardage needed for on game terminal velocity the wind difference between 2800 and 2900 isn’t much

I gained 120fps with 143s in my 18" 6.5 SAUM switching from Retumbo to N560. And I didn't run it up to pressure. I just found a comfy spot once the velocity was more in line with my expectations.

(Not a Tikka barrel, this is a McGowen...just relaying my experience switching to a Viht powder)

Like others have said, if you reload the issue more or less ceases to be an issue.

I've never touched a 6.5PRC but I can say that in my .280ai I was using IMR8133 for 180s and when that was discontinued I tried some VVN565 and gained 50' over the 8133, without even looking for max. I suspected I had another 50' left on the table.

25" Bartlein, Peterson brass, 180eldm at 3.43", I was topping out about 2825' with 8133 and the first load I tried with N565 was at 2870'. I shot 6-7 shots and saw no point in further 'development'. Gordon's Reloading Tool data indicates I had another 50' or so left on the table and based on what I saw (or, didn't see) on the brass I think that's accurate.

Point being, in the right size case, N565 is a great powder if max speed is your goal.
