hi john ...first of all, rifles tend to vertically string just because their barrels are attracted to the center of the earth . try shooting your handi-rifle lying on your side. and do take a selfie for us when reporting this new data point. ( g ) .
and in regard to vertical stringing and bore polishing .. one time a buddy was trying out his new sako finnfire ( 22 rf sporter ) ... drat !! 3/4 inch at 50 yards ... drat !! and then we noticed zero horizontal, 3/4 vertical ... hmmm ... scope screws check ... bedding check ....ok, try firelap with 250 grit ...4 shots later it went to roughly zero horizontal, zero vertical ... stop firelapping !! good enough .
rough chamber causing erratic ignition ?
btw, if you find a used finnfire sporter, grab it .. those are magic rifles, kinda like the win. 70 featherweights . and yes, the sporter outshoots the target barrel model ...
also i would try resting the hr on the barrel; the unmodified ruger one rattles when you rest on it's forearm. the win. 85 highwalls just have a lump of wood screwed to the barrel ... works great.
