Vectan data shows the following 20ga 7/8 oz loads:
Hull - Rem
primer - R209
wad - WAA20
powder - A0 16.0 gr
1200 fps @ 10,000 psi
Hull - WAA-HS
primer - W209
wad - WAA20
powder - A0 15.8 gr
1200 fps @ 10,700 psi
These recipes look similar to what is shown for Universal powder, but A0 must be a bulkier powder because Vectan shows a MEC 33 bushing throws 21.8 grains of A0, while Hodgdon shows that a 33 bushing throws 25.2 grains of Universal. A0 must also be bulkier than Unique as Alliant shows a 33 bushing throws 22.5 grains.
Is anyone out there loading either of these listed loads and shooting it in tubes? If so, how is the fit and what kind of crimps are you getting with the WAA20 wad which is probably the tallest 20 7/8 oz wad out there. What is your general impression of the target breaking performance?
