IMHO none of those are of worry to me. You can see the cannelure (crimp groove) in all of them.
They all look fine. There is slight variation in length but not enough to worry about.which ones look correct? For purposes of performing properly with regards to expansion?
Well I'd send them back, depending on your intended use. Ranger Ammo is not supposed to be civilian Wally Mart white box ammo.The Ranger line is generally supposed to be Law enforcement DUTY ammo and loaded to the highest standards possible by the manufacturer. Maybe the batch of Ranger ammo you have did not make the cut for duty quality ammo and was sold therefore on the civilian market. I am appaled by the quality control on alot of todays price leader ammo. Seating depth variation like that just shouldn't be on premium grade ammo. Being it is *P .010" deeper might just raise the pressure a few thousand pounds , but the longer ones might pull and tie up the gun because they are loose or vice versa. I guarantee the old Winchester Black Talon 20 years ago didn't look like that !
I think so too. I've seen some loose tolerances in winchester rimmed brass. Case length, rim diameter and OD near the case head are variances I've seen recently. All in different calibers, different lots and made many years apart. I'd wager OAL is all the same.I'd suspect that it was due to variances in case length
No I haven’t. I don’t own calipers so I don’t have any means of doing so accurately, unfortunately.Have you measured them and determined what the differences are in OAL?

Just check it by putting them standing up on a flat surface and put a straight edge across the top. if the one with only a sliver of cannalure is touching and so is the one with most of the cannalure showing, they're generally the same length. Just a comparison, precise numbers are needed .No I haven’t. I don’t own calipers so I don’t have any means of doing so accurately, unfortunately.
So I eyeballed them and it appears that the cases are the same length and the OAL for the deeper seated bullets is shorter.Have you measured them and determined what the differences are in OAL?

Hard to say, if the ammo is that inconsistent who knows about the powder charges . all things being equal , the same amount of powder in a smaller space will generate higher pressure , this variance is minor in your case and I personally would just shoot what you've got and get some better (more consistant) ammo. If it looks screwy from the outside I'm sure it's screwy on the inside too.So if you were to chronograph this ammo would you predict higher velocities from the deeper seated bullets due to a perhaps slight increase in pressure?
