Heading out to do chores and have a great opportunity to give the new ML a chance to take a nice boar. Trouble is by the time I could have broken it out, loaded, tamped, primed and been ready to get to stalking he'd moved well out beyond my current comfort zone so I just grabbed my stubby little AR with the EOTEC on it and with two quick pulls of the trigger one dead pig. What I'd like to do is to start carrying it at the ready so when similar circumstances arise I'm ready and can just pull it out and start the stalk. Is there any real downside to doing so? Shooting BH20 Scorpion 300g with black crush rib sabot and using regular shotgun primers. Once loaded and tamped down I should have any issue with loosening or moisture fouling the powder should I?
