In a telescopically extensible ammunition magazine for a firearm or similar device in which the rounds of ammunition are biased toward the firing chamber, by a coil spring, bent leaf spring or similar resilient device, a tensioning cord partially compresses a section of the spring preventing full extension of that section and causing the spring to snake and rub against the inside of the magazine or magazine assembly. The partially snaking spring is allowed to frictionally and incrementally travel within the magazine during reloading keeping each round properly aligned as each one is inserted. The extended length of the spring is selected to provide the minimum spring extension needed to feed the final unit of ammunition to the firing chamber when the magazine is collapsed to its minimum length. Ammunition can thus be conveniently loaded without having to compress the spring; yet the full strength of the spring is available to bias the rounds towards the firing chamber. Ammunition can be easily manually unloaded from the magazine.

A magazine and spring control assembly in combination with a shooting device having a firing chamber which can accept ammunition and a firing chamber loading port, said assembly comprising: a generally duct-shaped magazine having a primary dimension along said duct axis, said magazine capable of attachment to said shooting device at a mounting orifice of said duct axis and capable of containing at least one round of ammunition; a compression bias device loosely placed within said magazine, having an active end proximate to said mounting orifice and a reacting end distal from said active end, said bias device being placed and dimensioned to be compressed by said ammunition and to produce an extension bias force capable of moving said round along said primary dimension to said mounting orifice; and a tension member attached between two distal points of said bias device along said axis, said tension member being dimensioned to limit extension of said bias device between said two points.
