I have a custom 284 and really like it. The short action allows a really light rifle if you want. If you go with a long action, you might as well go with the 280AI. Using a short action (modified with a longer box magazine to allow 2.950 OAL) gives you all the velocity that the 284 has to offer. Using a long action is not justified with the 284. You can get a 140 gr bullet(best weight for the case capacity) around 3,000 fps+. Accuracy is excellent with a good barrel. Don't go too light with your barrel, as it will really effect your accuracy. Better to lose weight in your action, stock, etc with a little heavier barrel if you plan on a lightweight rifle. Good luck. /ubbthreads/images/graemlins/cool.gif
