I have a 110 Tactical in 7Rem Mag that I got thinking I was gonna have it chamber reamed into a 7 STW.
It appears that the action is long enough but the magazine is too short to handle the STW cartridge?
The rifle is a staggered feed, blind magazine in a tupperware factory stock.
I plan on using it as a long range deer gun from a fixed stand and would rather have a repeater than a single shot.

Is it possible to replace the magazine box and open the stock up to accept the new magazine?
Has anybody made this conversion?

Thanks in advance,
Howard
