MDT makes an AICS mag that should work, the round seems to fit in the Bighorn Origin action ... not a lot of room to spare but it fits ... please share what success or problems you've had doing this.
I have an unopened 8lbs keg of RL26 I want to trade for N565 in indiana. Purchased in October 2020 and has sat in my living room since. The only other thing I'd consider trading for is 450s. Not looking to sell.
