Just did a range trip with the G39 and G38. A couple of observations, 1. Federal Hydra Shok 230 is very snappy in the G39 2. Winchester Ranger 230 is very controllable in both guns and smooth shooting 3. Sellier & Bellot 230 FMJ ammo has some seriously hard primers. About 19 rounds failed to ignite first time out, 5 did not fire on the second try, and 3 took 4 strikes to fire off. And I only used 30 rounds from the 50. It does have that red laquer on it, don't know if thats an issue. I know its not the pin (all were through the G38) as the federal and Winchester had no such issues. Think I might pass on S&B in the future.
