Pat, You could if you wanted to. Most load the steel based hulls once and toss. Then again, life it two short to load cheap hulls. Hard on the resizer and hard on the Breach face and ejectors. Break-em all. Jeff
When you start loading the Winchester HS hulls be aware that the usual failure mode is a longitudinal split in the side of the hull (plastic) and not a failure at the case mouth. If you do not catch the split when it is small the case will split the full length of the plastic.
I would not be afraid to load the Estates multiple times. I load Federal Top Gun 12 gauge hulls 4 or 5 times with no problems.
