Sako Finnbear l61R Magazine Length?

[longrangewannabe]

I've searched everywhere for an answer but would anyone happen to know the internal magazine length on a sako finnbear l61r 7mm rem mag? Looking to convert to a 28 nosler but trying to make sure the magazine doesn't hinder my length too much. Thanks!

I just happen to have a drawer full of actions and I have an early 4 digit L61R that was a 338 win mag that should be the same mag box I would think. It measures 3.650 measuring at the center of each end on the inside of the mag box, Hope that helps you. I was originally going to build a 26 Nosler on this action, I bought the reamer the headspace gauges and the brass, But I changed my mind and I am slowly putting together the stuff to build a 300 PRC on it.

If I remember correctly 300 PRC factory ammo is 3.68 the 225 stuff anyway and 212 is 3.65

Thanks, I may have to extend the mag box and open up the rear of the action a bit.
