Ring, Do you specifically mean that you use Gold Medal data for the fiber base wad ones? The reason I ask is that I have a bunch of the fibers but there is far more data for the gold medal's, and I plan to load w/WW AA12's Thanks-Muddy
Lyman lists loads for the fiber based hulls using WAA12 wads.
-1 1/8 oz., 20grs. Red Dot, Win 209, 1250fps, 9900psi
-1 1/8 oz., 18grs. Clays, Fed 209a, 1191fps, 9300psi
-1 1/8 oz., 22grs. Am. Select, Win 209, 1245fps, 10400psi
This list includes 5 or 6 more loads with WAA12 wads. Let me know if you need more.
To your question. There are those who recommend interchanging the data between Gold Medals and Top Guns, etc. I do not and apologize for giving that impression in my previous post. It has been edited. Those that make this recommendation say it is safe but performance suffers using GM load data in Top Gun hulls.
Federal lists data using their components here;
http://www.federalpremium.com/downloads/reloading/FP294_ShotshellReloadingData.pdfFor my own use I do compare like loads and data from manuals to arrive at data I'm comfortable using. Many listed loads for the 2 hulls are very close in pressure and velocity in the various manuals. I might be flamed for admitting this but I do deviate from printed resources occasionally. You can arrive at your own conclusions looking at same. Another resource is Alliant. If using their powders you can email them your load and they will respond with suggestions.
The fiber based Fed hulls are good for one and done. I have used many thousands of them and currently like them for games and second shot of doubles. Once adjusted properly crimps are good. Hull height varies some and will occasionally give an irregular, deep or shallow crimp.
Hope I cleared that up for you Muddy. Sorry for much too general comment in the previous post. Let me know if I can help further.
