I have an umarex gauntlet 30 sl had it 2 months now put a tin of jsb exact diobolo 44.75gr thru it like a Lazer beam sooo pleased then 100 fx hybrid slugs ran great up till the last 3 shot 1 cocked the lever ,as I pushed the bolt lever closed felt like it was getting hung up before the probe enters the barrel shot 2 and 3 got more difficult so I pop the mag out safety on and tried to cycle the bolt.pull the lever back now volt only goes half way and stops ..calked umarex no response yet hoping warranty covers this 1 .any ideas guys? I'm not ready to take this thing all apart not that knowledgeable just yet ..
