Re: 338 lapua question
The OAL will change when switching bullets, since the contact band is different between different bullet types and brands. Additionally, your load development will likely involve changing the distance to the lands/seating depth in order to maximize accuracy for a given bullet. Similarly, different weight, or brand bullets can show a preference for a particular powder. I'm not sure from your post if you have tried playing with seating depth with your Barnes loadwork, but this may make a difference in your groups. Overall, changing your current Accubond load largely depends on your shooting requirements. The heavier VLD and match bullets will give a significant improvement in ballistic performance and energy at the extended ranges compared to your current load.
