5744 in .43 Spanish

[Bob Busetti]

Anyone using 5744 in the .43 Spanish rolling block ?

Bon,

I have used AA5744 in my .43 Spanish roller with moderate success under the Lyman .439 boolit. I am now using "surplus' pull-down SR4759 in part because it was difficult (and expensive) to get 5744, the 4759 was much less expensive and easily available at that time. Plus one uses less of it. Similar burning characteristics and accuracy. Both make good smokeless-for-black loads as long as you use good data and reasonably heavy for the caliber boolits.
