These are the magazines -
wisnersinc/model/savage-bolt-action-rimfire/ Brownell's used to carry the Wisner's magazine but list them as unavailable now. These magazine have good reviews.
Triple-K has them but theirs's are more expensive, but they do list all of the models they fit, which is a good reference -
triplek/product/savage-stevens-etc-22lr-5-rd/ triplek/product/savage-stevens-etc-22lr-10-rd/Triple-K's list - Fits models 1,2, 4C, 4CD, 4E, 7, 7A, 7H, 19 (not NRA 19), 23AA (not NRA 23A), 26C, 33, 34, 35, 56, 056, 56C, 056C, 57, 057, 65, 84, 084, 840S, 084S, 84C, 84CNS, 084C, 084CNS, 84CD, 84D, 84E, 85, 085, 85A, 85E, 85K, 85KE, 85H, 416, 420, 850,850H, Anschutz 54 Sporter, 141, 164, 184 & 1418, in addition to many private brands, Sears, Coast to Coast, Wards, etc.
(did they miss any??????????)
ADDED - I am not sure if it's the Wisner 5 shot magazines or someone else's, but some of the 5 shot are shorter than others and the bottom flange will not allow them to be fully inserted in a rifle with a heavy target stock like the later 19 NRA's or the Stevens Model 416.
