If the group walks as the barrel heats up,it is usually due to bedding issues or stresses in the barrel itself.
Agreed!
Some people leave it and except the fact that they will rarily need successive shots in the field. Meanwhile other will adress the problem by bedding/pillar, reaming the barrel channel, etc. It all depends on you what the next step may be. If it where me I would log a little more shooting time and try different loads, just to get accustom to the new rig and get a baseline.I would do the dollar slide along the channel to see if their was any stock touch, correct by hawging the channel and test. Next step would be to pillar and glass bed the action.Most of the time these will correct the walking problem, if nothave the barrel inspected and possible re-barrelled.
