I went all out had a full custom gun built for this round. will try to get pics up. First the surgeon action is one tough action. i just love the way its built. only thing i dont like is the remington extractor. but every thing else is tops. plus the rail is built in. let me put some more time in on this gun to see if theres anything i dont like. But about this round i just started to play with loads. this will take a while to get a good one never played with anything like it.One load got a ONE HOLE GROUP FROM A SUBSONIC ROUND but the pressure was a little too high.so more work ahead. All rounds going around 1000 fps. At 100 yards barely pushed by the wind . Went though a cider brick at 100 yards and though a cardboard sheet it has more power then i though. will do more test over time. Very quiet no need for ear plugs with out a can.but when i get my load done i will get you guys a db reading. Just give me time i gave up sleep to go play with this. Work keeps getting in the way of life.
