I did not have any luck feeding them out of my Left hand fixed magazine that was a 243 Win prior to being swapped to 6mm BR. In the meantime a 6mm BR detachable magazine came up for sale on this forum and I snagged it. I have not tried it yet as I would need to mount the barrel on one of my other short actions that are stocked accordingly because my lefty SA is presently wearing a 22-250 barrel it is shooting way to good to mess with going back to the BR cartridge and with no lefty stock inletted for a DBM.

Best regards
