I love the 5.7x28mm round and just found a very old thread on a custom Remington 700 in 5.7x28mm. https://www.fivesevenforum.com/viewtopic.php?f=16&t=11213

My question has anyone also done a bolt gun in this caliber? And who/what gunsmith do you think would tackle this job? I may do it if I could find one. Even the Ruger 77/22mag could be modified and rebarrled as a single shot 5.7x28…. Jump in anyone.
