Doonnzl, what you describe is a stovepipe. I don't believe a weak spring tension in your mag, would cause that problem as the mag ejector is as solid as the mag. I believe the problem is the subsonics, don't have quite enough umph, to maintain bolt speed to eject case, and overcome the std hammer spring. Also if your rifle is new (less than 500 rds) the action may not be completly broken in yet. If you try a higher velocity ammo I bet the problem would go away. I understand in your country gunfire sound is a problem.
Here are the things I would try:
(1) If you installed a match hammer kit, such as the Volquartsen, but kept the stiffer stock hammer spring, take it out and use the Volquartsen hammer spring.
(2) If you haven't already do the hammer mod. I can see it will really help over come the hammer resistance, it increases the mechanical advantage. http://www.perfectunion.com/forums/showthr...&highlight=bolt
(3) My last choice would be to replace the recoil spring (if you are only going to shoot Subs) with a weaker one. (scroll down) http://www.gunsprings.com./RifleShotgun/Ru...RsNF.html#10/22
