Be careful with 788 stock selections when buying used.
What they called short and long action is different than normal.
Boyds has the caliber attached to the stock at the bottom of the page.
Choose your caliber in the customization menu.
Pay close, very close attention to the distance between the action screws
I have several so I know.
I would cut yours and buy a Boyds later when she's grown.
There were tow types of stocks walnut and Beech
Whne you cut it, you will probably have to sand it down and refinish it.
Beech is tough to stain and finish.
I use Tru-oil over stain on the beech stocks.
Walnut I just use Tru-oil
Here's video on one that was refinished.
I use Lee Valley Dark Walnut stain on the beech ones with a Tru-oil top.
They turn out very well.
