Home Forums Reloading Big Game Rifles Good 338 Federal loads

For grins I tried H322 with the 180AB and 160 TTSX.

In summary, speeds were ok, but accuracy was fair with the 180AB, tick over 1", and downright terrible with the 160TTSX. In fairness, this rifle hates 180ABs, so the result was as good as any other combo.
