When i press the bullet in some go in just fine, other go in hard and i see copper shavings. This of course is probably affecting my groups. What am i doing wrong?

Are you loading rifle or pistol? Are these flat-base bullets?
Pistol, you can flare the case mouth to avoid shaving the bullet.
Rifle, debur more or the Lyman M die is popular for ever-so-slightly expanding the case mouth.
ETA: Typically, .002" of neck tension is what you want. In other words, the id measurement of the neck of the brass should be .002" smaller than the od measurement of the bullet.

you might try deburring with a VLD type of chamfer tool

Measure your expander ball in your sizing die.
Since you are loading .308 bullets, the expander should measure .306.
Report back.

I flair the case mouth on everything I load now instead of de-burring, it's much faster and easier to do(my trimmed cases dont have burrs though).
I run a Lee neck expander die in station #1 of my 550B to bell the mouth of the case just enough the bullet will sit in the neck and seat without shaving the bullet jacket during seating, this doesn't affect neck tension at all and a FCD in the last station removes any bell that may be left at the mouth of the case.

Ok, no problems with your expanding ball.
eta, reread thread.
Shaving copper with boat tail bullets....hum.
If mouths are deburred, this shouldn't be happening.
Are you using mixed headstamps? Mixing cases from a different batch and number of firings are mixed up?
Maybe some cases have different neck tension, so only happens sometimes.
Thinking out out load and typing here.

mixed yes. Hornady, winchester, and one or two remington. Im going to try to debur more/better
when FL resizing when pulling the shell out some do come out very very easy and some come out like they are tight, so i would assume that some have tight neck tension?
i think i have you stumped lol
edit, no range pick ups. all have been fired out of the box by me if it matters

You have pointed to the problem, your mixed cases.
Figure out what cases are good and which ones are giving you trouble.
Set the trouble cases aside.
Any of them mil cases?

Those look great. If that doesn't work for ya, then I'm with dryflash with it being neck tension different with mixed brass.
I will throw it out there again though as already mentioned. The VLD chamfer/debur tools work way better.

im going to order them if the local reloading place doesnt have them

The Remington brass is going to feel harder when sizing compared to the thinner Winchester brass. As others have said "different headstamps different neck tension" I use it all but keep them seperated.
