Well about a month about I picked up a south bend model 9A lathe and had no idea how to use it. Bought a few books and watched some YouTube and have successfully chambered my first barrel, threaded, and timed my brake. Picked up a 338 edge reamer and bought a 338 blank. Ended up being about 21" barrel. The max I can chamber is about a 23-24". I know the barrel is short for the caliber but this was an experiment and big learning curve. I am pretty happy with it so far. Haven't gotten to shoot it yet. The 1200 yard range that I have been shooting my 308 and 300 win mag don't allow the 338's due to tearing up the steel targets. I have found another place that is a bit farther that I will try eventually. Im thinking I will pick up a 308 reamer next as that is something that my friends and I all use. Her are the pics of it.
