Right now I have a new project and need some help.
I’m restoring a Winchester model 70 Pre 64 22 hornet caliber and I am almost finished, already find the most difficult parts I need and now looking for the easiest is where I don’t know what to do.
I need the stock and the floorplate but any place I look there is no information about those parts.
Does those parts be the same as any other caliber or are they specifically for the 22 hornet caliber?
I would appreciate any comment.

The pre-64 M70 receiver for the 22 HORNET has the same external dimensions as any of the standard caliber receivers, so any stock will fit. In fact all the pre-64 M70 receivers, including the long H&H magnums have the same external receiver dimensions. The only difference is that the H&H magazine box is a bit longer so a complete H&H action w/ magazine box won’t fit in a stock with the standard magazine well.
No worries with the 22 HORNET however… Most of the Hornets were made during the time frame where the low comb NRA style stock was dominant. Only a relative few assembled late in production had the MC comb stock, though some did so depending on your serial number you might be able to go either way.
As for the floor plate… It was a specialized part in that the slots meant to accommodate the magazine leaf spring of standard calibers had to be opened up a bit to accept the coil magazine spring of the Hornet. The Hornet floor plates were almost always stamped with the letter “H” on the inside. Finding an original H floor plate, especially if good original finish is an issue, may be a challenge. But one can readily modify a standard floor plate to work as long as “originality” is not a concern.
Hope this helps,

JMc, the bolt stop extension for the Hornet is 1.617″ long…..good estimate.
The firing pin spring dimensions are: 5.6″-5.72″ free length, 39 coils, .050″ wire dia, .402″ spring dia.
These dimensions are from the original blueprints. I have not verified either by physically measuring them, although I can do this if needed.
** I verified these measurements this afternoon. The bolt stop extensions varied from 1.605″ to 1.616″ long based on measuring 6 different Hornets. The firing pin springs measured 5.5″ long with a .050″ wire dia. I only measured 2 of these, one being an all original rifle my Dad bought new in 1948. I would expect these springs to loose a bit of length over 75 years due to fatigue and set over the years. Honestly, I think the standard spring would work just fine. They run about 5.3″ long and have a .052″ wire diameter.**
Hope that helps,
Steve, I called Classic Arms and Parts about M70 firing pin springs, they have both pre war and post war springs, but not the one for the Hornet. I was given a part number from a 1962 Winchester parts catalog of #7370. I am curious as to the differences with the standard spring.
Meanwhile I will be satisfied with a standard spring.
JMc, unfortunately, I cannot find my drawing on the standard fp spring. I have physically measured the springs, and the only significant difference I can measure between the 2 springs are the wire diameter, with the Hornet measuring .050″ and the standard measuring .052″. All the springs seem to vary what I call significantly in length, usually by .100-.200″ in overall free length. This go’s for both the standard and Hornet. I equate this to “set” and manufacturing tolerances over the years. Winchester was very inconsistent with updating changes to their engineering drawings. I have seen numerous examples of this over several different models, not just the 70’s. The spring dimensions could have been changed and never documented.
