I've found that with 185TSX in the 338Fed that I run out of powder space with my favorite powder sooner than I run out of space with 200 Speer LedCor bullets. Haven't yet spent the scratch to try 210 or 225 gr all copper bullets. Fear they'll be TOO LONG and unusable. Then here I'll sit, a poor wretch of confused humandom with a partial box of expensive copper jewelry to look at.
Will someone else please try the long copper stuff in a 338Federal and let me know how it goes? Please?!
