30-30 Winchester trimmed too short?

I was recently given some 30-30 cases that were sized and trimmed. When I checked them, they measured 2.032 and some 2.034. I checked my Speer Manual, and it has 2.0395 max and Trim to length of 2.030. I'm kinda new to loading rifle ammo so I just wanted to make sure that as long as these cases are between 2.030 and 2.0395 that I'm good to go.

Sure, the neck length doesn't control anything other than bullet support and the preasure/friction to release the bullet. It is a rimmed cartridge so even a neck of an 1/8" would work. It is best for accuracy to have them all the same length though.

They should be good to go. The Max is what matters, but even that is somewhat arbitrary and ultimately depends on your particular chamber. Trimming a little under the trim-to length is no biggie. On occasion, I've had to do it intentionally (by 0.010") to get a particular bullet to feed well in a leveraction.

If they're too long, you will get an increase in pressure (bad). On a bolt gun, you'll feel it binding as you lock the action. You may not be able to feel that as well on a leveraction. If you keep them under the published max length, you should be fine.

Uniform length (+/- 0.002" is okay IMHO) is important for uniform crimping. A 30-30 for a tube-fed lever action should have the case crimped into the cannalure unless you are SURE you have enough neck tension to prevent setback. From what you've described I see no problem with your cases.
