Home Forums Reloading Big Game Rifles Good 338 Federal loads

In my opinion, RL15 would be very slow burning for the 160 TTSX. Barnes reloading data uses RL 7 for the 160. RL 15 would be better suited to the 185 though. A faster powder such as AA2230/X-Terminator, H322 or even IMR 8208 will get you more velocity, likely much more with the 160. I got 3044 on the chrono with AA2230 (Barnes book load) and in the low 2900s with 8208 (Hodgdon book load).
