Looking for stateside smiths to build a 1909 Argentinian Mauser action into .404 Jeffery. Who do you guys recommend? The rifle will be in harms way in the future so feeding is paramount! A couple people I’ve spoke to seemed okay doing the rechambering but seemed less than confident on function due to unfamiliarity with the cartridge. But these were more locals who are use to 30-06/6.5 deer/target rifles.
