7pm mag rechamber to stw

[.284]

Anybody done this on a sendero and shoot 168 bergers? There's a bit of difference in the oal of the two and was wondering if you could reach the lands and still fit in the mag? If not does the stock have to be altered to put in a Wyatt extended box?
Thanks

Have it throated so they will. You can set the bullet back to fit the mag well and have the
chamber cut accordingly. If you don't have a 26" barrel you will be a bit disappointed. The
stw needs the length to burn all that powder.
