Hello everyone

I just got myself a KRG Bravo stock for my Tikka T3x Stainless Varmint 223.
Have got a MDT Polymer 223 magazine and it feeds nicely.

Now im just wondering if its worth rechambering this factory 1-8" Tikka barrel to 223 AI? Or would I be better served going to a 26" and 1-7"?
I want to shoot the 75 ELD M's around 3000-3100 if possible and use it as a longer range varmint rifle to 500yds or so.

The 8 twist is fine for 75 grain bullets. What's your barrel length? I'm sure 3000 FPS is doable in a 223 with 75s but barrel length will also need to be on the lengthy side.


ETA:

I went back to look at my dope and it seems I am pushing just below 3000 FPS on 75 and 73 grain bullets IN FACTORY AMMO from a 26 inch barrel 9 twist so if you plan to reload, I think you can achieve that.

Think the factory barrel is just shy of 24"
Around 23.5" or something.

So if I went to a AI I should be able to get over 3000 pretty easily then. Especially if I go with a 26" barrel

My Tikka barrel was relatively slow compared to other barrels in the same chambering, and this seems to be pretty consistent across the board for Tikka barrels.

That said, I would tinker with standard 223 loads and see what kind of velocities you are getting before making the decision to re chamber.

As a couple of previous posters have said, you might be able to reach your target velocity without AI'ing it using Alliant Power Pro 2000 MR powder. I get 2960 with 69 Sierra TMK's in a 16" barrel with really good accuracy.

I have a similar setup, Tikka T3x 223 in a Bravo. I went with a PVA 223AI barrel, 24” shouldered prefit. It is faster than than the factory barrel, more accurate (especially as it heats up), and has a threaded muzzle. I recommend it, Maybe even on sale this weekend. 80gr SMK, Lapua brass, 24.8 8208XBR, CCI450, 2.455” OAL.

Sweet looking rifle!! 500 yards with your current setup should be a chip shot. I can routinely make 500 yard hits on IPSC steel targets using my 12.5" Noveske AR with a 1-4x20 scope. I typically shoot a hand loaded hornady 62 bthp or 77 smk. I would just keep it as is and shoot the hell out of it.

Thanks everyone for the replies

At the moment I'm running 80.5 Berger Fullbores at 2830fps but this Factory barrel has a short throat which isn't ideal for powder space.
Can definitely relate to the Tikka barrels being slower than average, very accurate but not able to run the higher nodes.

Pretty interested to see how this turns out for you.
Right now I’m getting a T3x made up in 223AI with a 26” 8 twist barrel throated specifically for the 75g eld-m’s loaded for the longer MDT mag length and am hoping I will have enough horsepower to hit a node at or north of 3,000.
