Hi folks. I'm new to the forum and am hoping this post ends up in the right sub-forum and reaches a few Number 1 experts! I need some ideas on how to address vertical stringing with my 223 No. 1V. A little history first: this is a late model 1-V with a Ruger barrel. The barrel has been inspected by a BR gunsmith and was given the green light. The barrel currently floats, but I have tried different "fulcrums" between the forearm and barrel to establish different nodes, with no success. Trigger pull is set at a crisp 1 pound. The scope is a Leupold VX3 6-18 X40 MM with Leupold rings. The rings have been lapped and all screws torqued appropriately. I've also tried another scope and still get the stringing. I've tried MANY precision hand loads and my best results come from a somewhat mild 3,100 fps load: Berger 52 gr FB Varmint bullet, 25.0 gr. H335 or Viht n-133, and Fed 205M primers. I use Lapua Match brass which has been uniformed in all respects after one firing. I use a Redding body die with Redding competition shell holder, Lee collet neck die, and a Forster Ultra micrometer seater die. Bullets are seated 0.020 off the lands. Runout is virtually zero. My velocity ES averages 23 and my SD is 6. Despite all these efforts, I consistently get vertical stringing in my groups. A typical 5-shot group at 100 yards will have horizontal dispersion of 0.4", while vertical dispersion is 1.0 to 1.5". I observe this stringing whether I'm shooting off sandbags or my Lead Sled DFT. The stringing is not progressive, but random within a series. I've tried everything from holding the forearm down hard to nothing touching the gun but my trigger finger. Hard rest, soft rest, other shooters, it's always the same. :?: While I have a number of Rugers, I'm fairly new to the No. 1. I'm wondering if this is a common problem with this model and if there is an accepted cure. Any suggestions on what I should try next would be greatly appreciated! Thanks in advance!
