I'm new to reloading....

I am currently reloading 9mm with Campro 115 grn RN bullet. What should I target as the overall length? What is this bullet equivalent to? Are all round nose 115 gr bullets of the same length and shape....???

Tks.

For the gun or guns your planning on using it in you need to make a dummy round. Start by resizing a case and just barely seating the bullet in the case. Then chamber the dummy round until the gun is in battery. Slowly eject the dummy round and that's your max OAL for that particular gun. I would decrease the OAL by 20 thou and use that as your OAL. Make a few rounds (dummy or live depending on how you feel about cycling rounds in the gun) and rack the slide to see if they feed properly. It will also let you know if they fit in your mag.

The same steps go for any gun for finding your OAL.
 
What powder are you using? I'm somewhere around 1.105-1.110" for a 124gr RN behind 4.2gr Titegroup. I don't reload 115gr but I can check the books when I get home. You should eventually pickup a set of reloading books like the Hornady reloading manual. The other option is to check the powder manufacturer. They usually have recipies based on powder and caliber etc.
 
OAL is determined by YOUR magazine length and YOUR pistol chamber throat.

make a dummy round that is just barely short enough to fit in your mag. You should make about 5 of them and make sure that length does not cause the rounds to bind. That might be your MAX length for your gun.

I say "might" because it might be too long to fit your chamber. Chamber a round gently, and verify the slide closed all the way. Eject it and see if there are rifling marks around the bullet. If so, seat the bullet 20 thou deeper and try again. When you find the length that allows to to cycle 5 rounds without any sign of rifling on any of them, make a note of the OAL. That is the physical MAX length for YOUR gun.

You might have to seat even deeper if you have any fail to feed issues.

I find CZ and Norinco pistols have short throat chambers. I seat most bullets around 1.110" The actual length will vary by bullet shape, weight and brand.

This. Good old "plunk" test. If the ammo drops in cleanly and doesn't sit proud (or too deeply, that's another issue) and drops out easily when the barrel is inverted, good to go.
