444 Marlin Mag spring
Would anybody know the Free length of the magazine spring?
Had a fellow bring me his rifle along with a spring he acquired from Numrich and this spring has to be at least 2 1/2 feet longer than the magazine.
I need to get this spring installed before I can determine the magazine failure he unsuccessfully tried to describe.
This is the straight grip, 100 year commemorative with the small stock medallion.

Mr. Cowboy,
1)Take a portion of the spring between your hands. Measure the relaxed length & the compressed (hand tight) length. Divide the compressed measurement into the relaxed measurement to figure how much spring per inch.
2)multiply the magazine capacity (prolly 5) by the cartridge OAL (per the Lyman book it's 2.57. Add the combined length of the spring follower & the end plug. Subtract that + 1/2" for safety from the total length of your magazine tube.
You will have the working space for spring. Multiply the space by ratio from #1 to find the max. relaxed length (max. spring you can fit in the tube). Start there & if you have too much spring pressure to load the last round, cut it down 1" at a time 'till it feels right.
My Marlin had a fail to feed problem. With the magazine tube removed, inside the frame forging there was a ridge of flashing that needed smoothing. It was only about .015/.020 high but was enough that about 1 in 3 cartridges would catch & fail to feed.
Hope this helps, Jim0
