None that I have ever heard of but I believe their are some places you can get brass re sized for the cal.
This is one of my favorite rounds to build a varmint rifle for because of the accuracy potential of the round, even if they made a factory round the people that shot them wouldn't buy them except for the brass, these are excellent 1000 yd guns and custom ammo is the only way to bring the accuracy out of a long range shooter.
