how far off the lands would be a good starting point?
Also, all my brasd is Nosler once fired. I do not have a case trimmer yet. Do I need to be concerned with trimming the cases after just one firing? I had heard the ackley improved cartridges needed very little trimming due to their design, but again,this is my first shot at hand loading. I just tumbled, full length sized and knocked the burrs off the neck... Anything else I need to do before charging and seating?
