Few things have changed and I'm curious to hear your opinions on their affect to accuracy...
- took off my stock to clean some shit out, then screwed it back on
- change of suppressor. New one looks very close to the barrel at the shoulder (closer to chamber) but gap is enough for me to freely slide a piece of paper. I was paranoid that this may be touching the barrel and causing some issues?

Would either of these factors normally cause some inaccuracy? Otherwise it could just be some user error...

I will sight it in again anyway but would be interested to hear peoples thoughts before I got launching these expensive bullets down range.

Cheers

Is this factory ammo or reloads?

You'll get a POI shift if you have brass headspaced off the belt vs. shoulder.

If you have conventional dies and a factory chamber, you'll land up in the middle between the two until the bolt won't close, no matter what you do.

Look up the Larry Wills (Innovative Technologies) collet dies
