[QUOTE="royinidaho, post: 101100, member: 2011"] Welcome aboard..... Hmmmmm, where to start? Let's see if I have this right: Initial groups looked good. Took same loads 65.5 out again and they produced a vertical string. Did it again and got another vertical string.... Result 1.5" wide and 5" high. Correct? First observation is that 2 minutes coold down time is not very much time. But barrel heating shouldn't make "that" much difference regardless..... I would suggest that the vertical string is symptomatic of a condition being affected by barrel heating as the POIs go up as number of shots increases. Check the barrel channel. If its supposed to be floated it should be completely floated. That is a business card should freely travel from front end of bbl channel to the recoil lug. If its not supposed to be floated then the barrel should touch evenly around the barrel channel. I'm not familiar with Savage barrel bedding so I'm talking kind of generic here. If the barrel is supposed to be touching towards the end of the stock, you could cut a piece of business card about an inch wide and fit it between the barrel and pressure point. If things improve then rebedding the barrel and action would be suggested. Just a couple of quick things to look at. There are more but that's a start. Others will provide useful suggestions also. Go luck and good shooting.. How about the barrel channel. [/QUOTE]
