I know this has been discussed in the past but several searches has not turned up what I'm looking for. Terminology may be the problem. What are the usual causes for shots to string vertical and also horizontal. I'm shooting hand loads with each powder load scaled and col as consistent as I can get them. time between shots about two minutes with 5 shot strings between target retrieval and gun swapping. I'm having my shots string vertically up and to the left with each round down range. I suspect it may be barrel heat as the whole process starts over when I go back to this particular gun. The gun is a ruger varmitter in 22-250 bull barrel and laminated stock with no barrel interference.
