Rechamber scenario, a slow twist Valkyrie?

[gemihur]

What might one expect, performance-wise, if a 223 Wylde barrel 1:8" twist were re-chambered to accommodate the 224 Valkyrie and utilized a 55 grain bullet?
... just curious.
Thanks

I’d be trying a 69SMK before a 55.

OK, using a 69 gr. bullet, What performance gain might I expect with a chamber thus constructed over the existing one of from 31 gr. of H2O to one that allows a volume of 34.5 or approximately 11.3%?

You'd still be hamstrung by the twist.

The Valk wouldn't be enough of a step up to merit the expense of the work.

Thanks for your insight. It's actually marked 1:8 twist
I already shoot the 6.5 Grendel so I could use that BCG.
Would it not stabilize lighter bullets than the Valkyrie normally employs?
Was considering chamber improvement of that barrel and the Valkyrie offers about 13% more increase over what the Ackley improved provides.
Thanks again.
