Keep it clean
I slipped in the mud while out stalking and blocked my barrel with a lump of gooey muck and that was the end of my outing. I was so annoyed, but a mate told me I could have blown the barrel clear and just carried on. Is that true?
DOM HOLTAM replies: I wouldn’t have risked that. Firstly, you’d have to blow from the breech end (which isn’t very easy!) and even then, would you have definitely got all the moisture and grit from the rifling? Far better to keep a compact cleaning kit in your rifle bag or truck so at least you can return to your vehicle and clean the gun properly and then continue your outing.
The risk of not fully clearing the obstruction is at best damaging your barrel, at worst serious personal injury. Better to be safe than sorry.
