lapua,
Any photos perchance????
I don 't doubt for one minute that its mint, the Heym's are great working guns!
It would be great to see what it can do performance wise, might even be able to do Group 2 besides the stopper double event with it as well; those longer barrels will certainly help velocity wise. Any loading data will be great to add in if you do have any.
Cheers
