Try this method and the thread for this discussion is at the end
This is how I do it and it has always worked out ok for me:
Dice up the pork shoulder and pork belly (the fat is essential) I ususlly do 1 pork shoulder and 2kg of belly!
Add flavourings or spice mix
Mince in the mincer through a small plate
Leave to rest until chilled in the fridge
Add your rusk and water (after an hour or so in the fridge)
Re-mince, I do the second one through a larger holed plate for ease
Leave to rest until chilled again, in the fridge.
Mix the meat by hand (the best kitchen tools ever made) until all the mixture is sticky and gloupy (not sure if that is a real word) this takes me about 10 mins and I do it in batches. You could use a wooden spoon or something like that but clean hands are best.
While you were mincing the meat you should have had your casings soaking in water the time lapsed from dicing and mincing and cooling will be ample for the casings to be pliable for use. Always run cold water through them to flush out any salt from storage.
Load the skins onto your stuffer and stuff...do not put too much in as this will cause bursting and the leakage you write about.
An extra pair of hands on the stuffing end will leave you free to control the amount of casing you allow off the stuffing tube.
I always leave a good bit of casing on the front and end (about 2/3 inches) to allow me to push any over filled areas of casing to each part and therefore avoid overstuffing.
This always works for me. Taste is great and no bursting or leaking!
Keep going it will get better for you
