Wow, I wish they had told me that! I have an SP10 in 6.5 and it shoots lights out, I recommended it to a friend, he bought one, and it had to go back due to FTE, FTF issues. It went back, they worked on it, and sent it back to me saying it was an extractor issue, now fixed, all good. I wish they had mentioned the ammo bias issue.
And if anyone needs an SP10 in 6.5, I have one fresh back from Seekins, still sealed in the box, they say it runs like a top now. The friend lost faith in the gun, so now wants to sell it.
