    I shot my .500 handi rifle today, and I had one round of 350gr doubletap that I think may have been loaded too hot or something.

    Out of all the ammo I've shot out of this gun so far, the 350gr DT are the hardest kicking. The 500gr hornadys and 440gr silvertips are probably second place as far as recoil is concerned. Anyway, I had already shot 3 or 4 of the doubletaps, then I shot another, and I couldn't get the gun to break open. I had to smack the barrel really hard to finally get it open. The case wasn't any harder to eject than the other ones, but it did seem to have a little more discoloration than the other brass.

    I checked the gun over real good looking for any visible problems, opened/closed the action several times to see if there might have been a problem with that, and didn't see anything wrong. So, I went ahead and shot a few really light 300gr rounds through it, and then a few more doubletaps and silvertips, and never had anymore problems breaking the barrel open.

    I've seen on youtube were some of the early handi rifles in this caliber had a problem with the barrel opening after shooting it:uhoh:, but I don't know why I would have one round cause such a difficult time of opening the barrel. Any ideas?

    And on another note, I had read on a lot of threads about these guns that the sights break on them a lot. My sight hasn't really "broke", but the rear sight insert slides out of the sight base while being transported on a regular basis now, and it's a real PITA to get it to line up to fit back in sometimes. I don't really want to superglue it or something in case it breaks again and causes me to have to spend money to replace it, but with a sight that falls off as easily as this, I wouldn't want to pack this gun through the brush where bears frequent, unless I was just going to point aim it and hope that my natural instincts are good enough to keep a Yogi or Boo Boo from stealing my picnic basket.

    Probably heat expansion. A lot of rifles get stiff when they heat up, the Mosin Nagant being one design in particular. Your rifle's a lot more powerful than a Mosin Nagant, and will likely have even worse heat problems. Hot loads will also, surprise surprise, increase heat. The discoloration on the brass is also indicative of high heat.
