A few years ago I bought a heavy barreled [very heavy] rifle built on the FBW Action and chambered for the 40 Krag. That is supposed to be the old 40-60 Maynard case. Sounded easy and the barrel although heavy is a work of art made by Bo Clerke who was a real craftsman. My idea was to use the rifle for black powder shooting. Along with the rifle I got three bullet molds and a 20 power Lyman STS scope. What problem could there be? All you had to do was expand some 30-40 Krag cases, or 303 British if you can't find Krag cases. The 303 is 2.222 in length and the Krag is 2.314. Was I in for a surprise. To began with, you can rarely find the Krag case and when you do they are two bucks apiece. I have some Krag cases and no two of them are the same length and no where near 2.314 in length. The same can be said for the 303 British cases. I am about to toss the whole business down the well.
