Winchester Super Target

[John Dallas]

Does anyone know the pressure data for 12 gauge, 1oz 1180 fps load?

[Fred Lowe]

In the Winchester 14th edition reloading manual, I show:
AA hull, 1 oz, Win 209 primer, 19.5 gr.WST powder,Win WAA12SL wad, 1180 FPS 7,100 psi
It reads "this load duplicates the ballistics of the factory Winchester AA Xtra-lite target load"

The same load w Fed 12SO wad shows 8,000 psi

This would be with the "old style" hull.

The following is from the Hodgdon site for a Win HS case with 1oz load of lead

Winchester WST, 19.5 gr., Win. 209 primer, WAA12L Wad, 8,500 PSI, 1,180 fps

I have been shooting that load out of an 1881 Lifter Parker with Twist barrels for over 10 years without incident.
