I too have not been able to contact them, I had a barrel that was up for a June production but so far I have not received a return call from a VM I left or replies to text messages on status so I am just waiting and hoping  all is well with Gerald.

I have 16 or 17 of their barrels in 22rf and depending on which action, what twist, ammo, conditions, day of lunar cycle, etc. they shoot well.   My best shooter is a Turbo with a RKS barrel, next are probably a couple of Ballards with RKS, followed by a Remington 37 and I can go right on down the list, Winchesters, more Ballards, a couple of rollers, a pair of Hepburns, a Webley, Farrow, a Westley Richards, a Zettler and even a couple of Martini's but running neck and neck my worst shooters with RKS barrels on them is probably a Hepburn and a 1-1/2 roller.  They not terrible, but they're not 1/2 or 1/4 MOA rifles. Don't be surprised if a new barrel doesn't fix your problem, your action screwed on to that barrel is a Hepburn isn't it?  I've shot silhouettes with one of my Hepburns and ended up fairly well but at a 100 or 200 yard Schuetzen targets I can't generate scores much better than a 230 benched, I've been in the mid 240's several times at both distances with a Ballard, Peregrine and a High Wall. 
As for the dollars spent, the last 6 cut rifle RF blanks I've bought this year domestically, run between $450 and $600 depending on the name.  Except for one, the RKS didn't give up any in a performance comparison.
Just a nickle's worth of opinion.

I wouldn’t expect less than 1 MOA groups reliably from any 22 rimfire bench rest from bags outdoors. Some may achieve it at times. 

Machine rest indoors is the test, too many variables otherwise

Johnny,
The shortest RKS barrel I have on my 22's goes against what everyone says, 27.5" is my shortest.  The average barrel I cut at 30".  For indoors at 50' my bottle cap gun wears a 30" LH GT 1:16, for my outdoor 50 and 100 yd rifle, a 30" LH GT 1:14, for the 200 - 500 yard it's a 30" LH GT 1:12.  They are all octagon and most are a heavy contour.  I cut my chambers the same, using a Calfee I carbide reamer or a Kevin Nevius reamer and I have made burnishing tools that match the reamers that I finish with.   
I shoot exclusively Lapua CX with one rifle that does a tiny bit better with Polar.  I buy ammo either one or two cases at a time and I've had folks ask what if a lot I buy doesn't work? I work with a barrel until it does or I pick another barrel and make it work.  I have one rifle, a Low Wall that shot most CX well but not like I thought it should.  It shoots very well now with lot that didn't shoot very well in anything.  When I was done with it, the barrel went from 30.5" to 28" due to experiments.  There's a lot of time and energy spent in my shop chasing details, for that I'll never build for anyone else... maybe a grandkid it they learn to truly appreciate it?
Another nickle's worth of deets.

All the Winchester model 52, Remington 37 and so forth had 28 inch barrels and seemed to do quite well, never saw one with a 20 inch tube. I had a very early 52 that would print sub quarter inch groups at 100 yards regularly when the wind was down and I was up. Wish I had kept it as bought from a much older gentleman who held records at that time and told me stories of sharing rides to Camp Perry with John Redfield and Matt Canjar. Also wished I  had recorded some or all of his stories.
