I played with the 6/250 AI for a while, about the same as the Creed, perhaps a tad more capacity with the 6/250 AI . With the creed, you will stand on the loads with max pressure where the 243 AI will be loping along.
As another smart poster mentioned, there is OAL to take into consideration, so plan ahead. Consider Wyatt's mag boxes, detachable mags for your OAL's.
Of course, your freebore constraints will hamper or help, choose your poison, and I highly recommend the 6x47 Lapua due to magazine constraints and accuracy, IF you are not wanting to get max velocity out of your 105's.
