I want to try some lapua scenars or some bergers and some match kings in my 243 AI. I'm worried that they won't fit in the mag box when loaded to just off the lands. I don't want to use it as a single shot if it can be avoided. I will however consider it if you guys think the trade off will be worth it. I'm using this gun as a longer range deer and coyote gun so a second shot may be required. What do you guys think? Am I totally out to lunch or what?
