Thread: .223 Ackley Improved

I have a spare unused Remington 700 SPS Tactical lying about. 223 1:9. Where could i get it rechambered to 223AI and what would be the rough cost. Am in Wellington area.

Give Robbie Tiffen at Gunworks a call, he has the ream that did my chamber and he will do it right.
To get a chamber that's right you'll want to at least set the barrel back one thread which will realign your factory barrel markings and give enough room to clear your new IMP chamber. it is a fairly quick and easy job so wont cost a lot. The new dies will likely cost more.

I used to borrow that reamer from someone, can't actually remember who, but anyway we aren't re-reaming tikka chambers these days as the hammer forged material reams badley and has cost us money to replace them so we won't be doing any more at this stage sorry

oh... I thought it was his.. interesting comment re Tikka barrels.

I just spoke to Arthur Cleland and he has the reamer and the no go gauges..

Ask Kiwi Greg to confirm this, I believe he reams a lot of Tikka barrels.

Could also ask about 22-204 as I believe he can, or at least has had reamers for this in the past.
Offers slightly better performance and avoids the need for fire forming brass.

The only Tikka barrel we will ream/rechamber are the 223 out to 22 Terminator (22-204Ruger)

Stopped doing any others years ago, way too inconsistent & hard on reamers even brand new ones.

Big difference between 223 & 22 Terminator if you use the right powders.

You mean you wont do any other Tikka barrel or just Tikka 224 barrels?
Is this attributed to hammer forged barrels being high quality or just don't lend well to reaming?
