FC factory ammo is also pretty average with headspace/shoulders. In fact I have some factory FC .270 ammo I've had to bump the shoulder back to chamber in forum member Broadleaf's Sako .270.
The mark is prob just from chambering the round, don't be too worried, unless you truly have a crooked round (run out).
Dies, press, powder and primers are good.

I wouldn't shoot off a bipod off a table, as it tends to vibrate and effect the harmonics, shoot either off soft ground (ie grass, or a exercise mat, not concrete) with the bipod, or a sandbag on a bench.
Also the bipod may be causing the forestock to touch the barrel, so check the barrel clearance.
Shooting off a sand bag should be better, as the pressure on the stock is further back.
Try to use a rear bag as well, if you don't have one, use a pair of thick socks held in your left fist, with left arm (assuming you are a rightie) tucked back. Squeeze the sock to raise stock and lower aim, relax fist to lower stock and raise aim.

Thanks for the info. Yes had a rear bag under butt. given the location shooting off the ground wasn't possible (chewed up winter kale strip)
