Thread: Case sizing and O.A.L

Hi all,

Very new to reloading etc and trying to take it all in is fun to say the least.....especially when you have experienced people to talk to who have differing opinions! Anyway.....to my question:

I loaded up a heap of .270 ammo the other night and the OAL on them are not all consistent. To me I didn't think it was going to be that big of a deal but apparently it is. They are maybe a maximum of 1mm difference (non digital calipers so roughly guessing) Now are they differing in OAL because maybe the case sizing's are inconsistent by - say a maximum of 1mm or should case sizing not alter the OAL? The bullets are SST so I can understand the polymer tip on them are probably not all at the same height. Cases are all the same brand and once fired and also the loading was all done in one hit (fuck i'm slow at it!!! still fun though )

I hope I'm making sense?

Cheers,
Grunta
