A few months ago, when buying Heptavac at the local agri. store (very well known), I was persuaded to also buy the Heptavac injector. I did not like the idea of using the same needle on all the sheep but could see the advantages of using a multiple injector. I used it on the ewes successfully pre-lambing, and cleaned it thoroughly.
Today I have tried to use it again for the lambs but the liquid is trickling down the outside of the tube below the 'gun'. In the end I gave up and went back to individual jabs - but I have wasted 5 doses out of 25. Has anyone else any experience of these multiple injectors please?

We have just a plasticky little gun thing and change the needle between each jab. I get the cheap one and get a new one every year as they don't seem to have any endurance.

I used Heptavac-P on the moorland farm, where we were injecting 530-ish ewes each year, 60-ish of them twice, and never had any problem.
It sounds as though the needle is not quite properly seated in the seal? Or maybe a split in the tube?
