Re: Nosler Accubond Long Range problem
This is an old post but just found it searching for info on the150ablr in my own 270wsm. Haven’t read all 51 pages of posts but have read some of them so please excuse me if this has already been suggested. Has anyone looked in the bore with a borescope to see if there may be a section with marginal lands or built up copper in one area? I assume the ablr has less bearing surface than other non-lr bullets. If only a small section of the bore had marginal grip combined with a bullet not having a lot of bearing surface then at some increasing velocity the smaller bearing surface bullet would slip and skip in that section before re-engaging. This results in a proper twist stabilized bullet but with a number of physical inconsistencies.
