IF I'm going to drop a LOT of coin on a full out custom rifle, it's going to be chambered for a cartridge I will shoot a bunch (no heavy recoil etc) and for something that I ain't gotta change out the barrel in 1000 rounds.
No disagreement here. That's why my first two choices were the Hornet and .30WCF. And I am leaning heavily towards the .30WCF. Low pressure round. Good brass life. Practically unlimited barrel life (more so with cast bullets)...plenty for my purposes.
The Swift is just one of those creeping thoughts. I admit it would be better served in a light bolt rifle build and not chambered for this project.
