[QUOTE="Shane Lindsey, post: 2631608, member: 25831"] What were the powder charges you tried? Close to or over max? I only know N570 with mine. I recently picked one up from [USER=103316]@Rum Man[/USER] who was scared he would have to change his name to Lapua Man 🤣 Being in the component crisis we are, I loaded up one round per one grain increment looking for pressure. Picked .030" off the lands as a start point. I actually load two at each increment. One to shoot and mark the charge and then another with the Magneeto speed on another target to see where they are with velocity. Berger 300gr OTM N570-86gr-92gr and settled at 90.8gr. Peterson cases Fed 215 mag primers I do this to see if there is potential and if the impacts are relatively close together as I go up in charge weight. This is my first 338 Lapua and it took a few shots to just go with the "I am getting in a fight, suck it up and take it like a man" each time I pressed the trigger. Significantly more than my 300 ultra with 245 Bergers. Some of my groups looked similar to yours, until I mastered this ^^^. No experience with the Accubonds, but from other rifles, you may wan to look at a good bit .050" jump with them??? [/QUOTE]
