NewGuy - you are spot-on - directions are there to be followed. Failure to follow such can ruin your day or worse.
: Note that virtualy all the older writers now do not mention using fillers, or that they used them for decades without misshap. Throw in a bunch of non-thinkers into the crowd, and everyone must now say that rung barrels or other problems may result. These old timers continue to use fillers in their proper application and without mishap. It is those who second-guess, jump directions and 'know better' who have problems, then cry for salvation when it's too late.
: As I noted, people, to this day are still sticking 7mm Mausers into a 7mm Rem mag. The "light mag", "heavy mag" designations have started a whole new flurry of black faces.
: A guy picked up a dropped wildcat round at the range and since it chambered in his .30/06, he fired it. Lucky he was as the case was a full 1/8" shorter than the '06 case. just becasue it says '06 doesn't mean that's what it is, especially at a range where I shoot.
: What all this means is that people do stupid things. Supid is as stupid does.
