Is the 338 Lapua the only solid top "target style" long action offered by Savage either as a rifle or a bare action?

Not sure on the terminology to use here - referring to the target style actions or the 338 Lapua action where the top of the action is solid, no cutout that would be bridged by a one piece base on a regular action, having a substantially smaller loading / ejection port compared to the regular actions.

I am aware of the single shot target short actions. Is there anything like that but in a repeater?

Have any of you had your single shot target actions opened up to work with AI style detachable magazines?
