The size of the bead you apply depends on how you cut the nozzle on the caulk tube, so do so carefully. Then, puncture the inner seal on the tube with whatever you have handy.
A stiff wire works great. You can now insert the cartridge into your caulking gun and begin sealing. Be sure to apply even, constant pressure to the gun’s trigger so your caulk will exit the tube at an even rate.

Smooth it out
Let’s face it, if this is your first time using a caulking gun, you probably won’t apply the caulk completely evenly and perfectly. That’s OK. Even pros need to smoothing tool, or their finger, to ensure the bead of caulk is smooth and clean.
To fix any mistakes that were made along the way, be sure to smooth the caulk two to five minutes after application. It needs to set slightly, but letting it set too much makes it impossible to smooth out.
Clean up and prepare for next time
If you’ve got caulk leftover in the tube, you can’t just put it aside and expect it to be used when you need it next. Squeeze the tube until there’s the slightest bit of caulk coming out of the nozzle, then replace the cap, or insert a nail to keep the opening, well, open. If there’s caulk around your surface that needs to be cleaned, mineral spirits are great for cleaning up silicone caulk.
