Well on my stock savage body i used a good pair of fiskars and cut out the whole windshield. Worked great, could carry by handle and turn off Rx w/o removing body or bending it upward(very convenient)

it didnt appear to loose structural integrity (no cracks or splits and the body is thorughly whooped, but still in use)

On my new body, i bought the whole reamer so i just reamed 2 holes in the center of the windeshield. But im not happy with this set up, cant carry by handle and hole is too small ti fit fingers to turn off Rx. So i will probably just use lexan shears (also bought with new body) and cut the whole window out on it.
