Would an American ranch be suitable for prs matches?
It would be suitable to shoot bullets in a PRS match. You would not be competitive with it.
What's the best barrel twist for the 55gr FMJ bullets?
Probably doesnt matter that much. Standard 55gr bullets in a mass produced factory load aren't going to be accurate enough for twist rate to matter much.
Lets put it this way. When you get bored shooting inaccurate 55 gr bullets, whats the bullets you are going to want to shoot next, and what will the best twist rate for those bullets be. Answer: 1:8 or faster.
Personally, I've been looking for a sub low caliber training for PRS match practice. For matches themselves limited to only factory guns, I think you either need a 6.5 or a .308. Only a very custom .223 would be competitive.
I've yet to see a factory gun in .223 meet the basic minimum requirements, and the closest match I've seen is the Tikka Tactical.
Twist 1:8 or faster, ideally, 1:7.
Barrel, 24" minimum, ideally 26".
Detachable Mag with 10+ minimum capacity, ideally uses AR Mags.
Under 10 lbs. Ideally under 8 lbs.
Readily available oversized bolt knob upgrade. Ideally oversized bolt included.
THreaded for muzzle brake. Ideally with removeable muzzle brake included.
Adjustable cheek height and LOP. Ideally with readily adjustable 6 way stock.
Matte Black, ideally some colour other than black, but definitely not stainless.
Sub MOA accuracy. Ideally sub Half-MOA accuracy.
There are a couple barreled actions that would meet most of these requirements if you put them in any of the good chassis systems out there, except for maybe the weight.
Any factory gun that met all the minimum requirements would be hundreds of dollars cheaper then buying a gun with the right barreled action and putting it in a stock.
I honestly don't care what it would cost as a factory gun, because not having the hassle of going custom would still be cheaper.
OH, and in a perfect world I'd buy it off the EE used, BNIB unfired condition for half of retail... lol.
Every time a new .223 precision gun comes out it seems to be close, but not quite. The savage Axis II precision for example., but the barrel is too short, and its unclear if the oversize bolt knobs for the model 10 fit on the Axis. Big of a goldilocks problem. The Mossberg MVP -LR or Precision would probably be as good as it gets, were it not for the fact that its a Mossberg, and for some inexplicable reason went with .224 Valkyrie instead of 5.56mm
