They're a bit barrel heavy, as Winchester (NH) used the same contour for their .416's and .458's. And, those had a lot more metal removed due to larger bore diameter. And these W/W barrels are way too good to discard.

So, cutting them to 21" or so seems to be about right. And, with a round like this, you don't lose that much velocity, not enough to worry about, IMHO.

The Tupperware stock seems OK. I jerked the hot glue bedding out, Steel Bedded the lug, drilling around in the stock so the bedding material would self lock. Not much sticks that well to Tupperware.

The Classic stock shape is pretty good, not quite an Echols Legend, but $600 cheaper... whistle
