Magazine Spring

[Arizona Trooper]

I got very lucky and picked up a Wilder Spencer rifle last week. It has the original magazine and square wire spring. There was some discussion a while ago about these springs, so here's the details. The wire is 0.045" wide, 0.035" deep radially, and the coil diameter is 0.6". Hopefully a photo will appear below.

The bore on this rifle is nice. If everything else checks out I will be shooting it at the N-SSA spring National.

Very thoughtful, Arizona Trooper:

Many thanks for the helpful details.
Dealers of original Spencer parts have shared it's been many years since they have seen the flat wire version.

Am happy to send you a round wire one, gratis, to substitute.
Just PM me please.

The coil music wire repro springs from Romano which function well are:
Relaxed total length out of tube:  16 5/8" to 17 1/8".
Wire diameter:  .029" - .030".
Coil OD at rest: .563".
Coil separation at rest: .260".

Spring engineers indicate round wire springs twist during compression and relaxation.  Am not sure how or if this matters.
