I converted one of my carbines to 5.7 MMJ several years ago. The bullets I was using required no modification to the .30 feed ramp.
These bullets are no longer made.
I need to modify the feed ramp to allow proper feeding of the cartridge. Jonson knew this and did add to the .30 feed ramp.
Do any of you have one of the converted carbines where you could take a photo of your feed ramp?
Thank you.
