Frankly I'd rather have a 6mm Valkyrie or 6mm Grendel with serious factory support. You'd be able to hunt with it in most states (unlike 22 Valkyrie) and there are tons of high BC bullets already in the pipeline for LR shooting.
I'm suggesting that the 90s may not currently be up to snuff. I shot a 1:7 twist prototype rifle last fall and managed a 5 shot MOA group with a pretty poor stock/shoulder weld (rifle belonged to someone 3-4" shorter than me) and took it to 1k at a DA of 3500 with ease. The Sierra ownership change could be a spurious correlation, but is worth noting. There was a time no one thought International couldn't make a decent medium duty diesel engine. Which is why the market was suckered into buying 2 million 6.0 liter Powerstrokes 10-15 years ago.
It could be that Federal and every barrel manufacturer got it wrong. And that standard twist rate models work for every bullet out there except for the 90 gr SMK. Or maybe not.
I personally don't have an interest in it for target shooting with my main issue being spotting impacts on steel at range. Plus I'm liking my 6mm Grendel barrel just fine without factory support
I do have an interest in fast 22 cals due to CO varminting laws during big game season, but the rebated case head on 22 Nosler doesn't work. Based on the velocities I was getting with 22 Nosler, the Valk's smaller case volume and faster twist rates, I don't see it being more worthwhile than 223. I do wish someone other than ARP made 22 Grendel barrels AND offered a slower twist.
Let's go Brandon!
