I just bought a Steyr Mannlicher MCA .30-06 and am considering sending it off to JES to have it rebored and rechambered to 9.3x62mm. First let me say that it is not a collectors piece and has had a pad installed and the white line spacers removed. The rifle will be here next week and I will check the magazine with some 9.3 cartridges to see how it does. If it doesn't feed are there any gunsmiths you can recommend that work on the Mannlicher magazines?
