I have a rifle that will shoot several loads into a ragged wormed out hole for 4 shots and one will be about 1/2" outside the group, It don't matter it could be the first shot thats bad or any of the others, there is no particular pattern to it, just 4 shots clustered all together with one flyer always, I am just wondering if there is anything that would cause this, and also would skim bedding the aluminum bedding block cure the issue

1/2" flyer in a five shot group?

Around my house we celebrate those type of groups.

I know I know, if the gun where my hunting rifle I would be happy, The gun is a HB varmint rifle, it just shows a pattern of doing this everytime, I want the gun to shoot to its max potential and if there is something I can do to correct it I will.

2/3 rds of all the benchrest shooters in the world have the same problem. Do you use wind flags when shooting?

this last group I shot for instance the flyer was low and left, if It was just a horizontal flyer I could see how wind could be a factor, although it was a pretty calm day yesterday. does anyone think skin bedding the bedding block would cure the issue??

5 miles an hour wind difference will move a 243 100gr or 22-250 52 gr bullet .3-.4" at 100yds. It doesn't take much wind to make a ragged hole a .5" group

It can't hurt, but unless the fit with the block is way out of whack, or, the action is on a bind, I doubt it's a cure. Is the barrel floating and if so by how much? If you smack the forearm in an upwards direction with the palm of your hand can you detect any contact with the barrel? Hows the crown? Is there any heavy deposits of residue around the crown? Are you canting the cross hairs? are you in tune and in sunc with your pulse? Are you sorting your brass by brand and weight? Are you feeding from the magazine, or, one at a time off the bench? For that small and random of a discrepancy, it's probably more likely to be a procedural problem than mechanical.

Would this rifle by chance be a left-hand Ruger M 77 in .270? If so, I sold that one several years for the very same reason. Bedding, crown, nothing helped--but you are doing better than I did for sure.
