Win 70 Mag follower length for Magnum length

[letzhunt]

Looking for the length measurement of the follower in a Win Model 70 in .375 h&h, 7 STW, 300 Weatherby or .416 REM Mag. Better yet to find one! Hard to source one so I am planning to Tig some to the rear of my shorter one to better fit the mag box and prevent bind. It's for my 458 WM+.
Any help would be appreciated.

That is what I did to my old 300 mag.
I actually took out the little spacer in the box so I could seat my bullets out next to the lands. Then extended the follower as you are about to do. Welded it up followed with some grinding and polishing. Worked fine.

so what length is your follower now. Haven't got a reply from anyone with the longer one to know about where to go. Easy enough to make it fit though by grinding. Was your follower Stainless?

Magnum (375H&H) follower is 3.5", standard length (458WM) is 3.34".
Both measured as they sit in their spring.
I tried to get a new FN Herstal magnum length follower and was told it is a 'Restricted' item for sale.
My solution was to use a Kimber from a Talkeetna, not cheap…

Cheers.

Depending on the age and amount of use of your 458, you might also want to check/replace the magazine follower spring. My 458 Model 70 was having feeding issues. Turned out it was due to a WEAK follower spring. Perfect feeding was restored by replacement. I believe the the weight of the heavy 458 cartridges routinely loaded to capacity in the magazine caused the follower to loose/change tension, causing binding/feeding issues.
