I'm so enamored I'd like to do a 22PPC in a repeater
I started down this road in a CZ 527 but stumbled across a deal for a $350 NIB CZ 527 Varmint 1:9tw in .223 Rem. For me the objective was to go *cheap* for volume shooting at the local matches and plinkng out to 1175yd at a friend's place in the mountains. PPC has more capacity than the 223AI and more room in the mag for the long pointy projectiles in a micro-mauser action. However, for me, the inexpensive .223 Rem brass, dies and projectile cost won over the PPC/22 Grendel I was lusting over.
Can your .223 throw 88-95g projos out to 1100+ yds supersonically?
That's easy, at least at my elevation especially with the higher BCs than the ≤77 class projectiles.
The Valk doesn't make much sense to a reloader/wildcatter.
This is true. If you're stuck with the factory offerings then the options are limitless with the .223 Rem, however .223 Rem will never have 'stunning' performance when loaded short OAL with light(er) projectiles and low (SAAMI) pressure. Then again, will the .224 Valk? Is it cost effective in any platform?
There's also the .22 Nosler. No weird boldface similar capacity and performance as the Valk and PPC.
