Welcome to the boards! It seems like you've done your research... Kudos to you!
So long as the remote lined tank is vertical, it should work great. Are your chops primarily in the breech/feedneck area, or the barrel?
If it's in the breech/feedneck, definitely the hopper. If it's in the barrel, that's a bad ball/barrel. Also try decreasing your ROF to ~8bps and see if that helps. If you have a gravity feed (shake 'n bake), decrease it to 4bps.
