	Good tip Web, I hate cheap no good tools and most tubing cutters are built to sell not work Boats

	Buy yourself a jeweler's saw and a pack of blades. Trim a little long and then run through your case trimmer. Won't set you back too much and should get you going without too long a wait. Jeweler saw won't collapse the case like a tube cutter or hack saw. (You need to *Login* or *Register* to view media files and links)

	Reiteration : I mandrel sized to the correct O.D. that matches a (non-bottle neck) cartridge case I.D., and which is inserted into the case prior to cutting, will, in fact, fully support the case and prevent its collapse during the cutting process when using a tubing cutter with a sharp cut-off wheel. Using any type of saw is less precise and just complicates the cartridge case shortening process and leaves the case interior full of brass chips. Question asked and answered. C.M.M. .

	I measured the thickness of the brass in the neck area of 40/60 Maynard cases that I've made from .405 brass. It measures .012-.013" thick, so the diameter of the loaded round at the neck will be .025" larger than the bullet diameter. Mine is a modern barrel with .408" groove diameter and I shoot .409" diameter bullets.

	I contacted Steve Brooks and am sending a slug from my barrel and a check to cover a new mould. I've measured that Maynard bore so many times and still come up with .410 so I have hope that the 405 case will work for my gun. I know for sure that the 30-40 blown out case will not work. My chamber is to large. I tried the tube cutter on one of the 30-40 cases and made a perfect 40-50 SS case out of it. So now I can try the new case out on a high wall I've had for some years. I've used had some cases from RMC co. but now can perhaps use these also. Thanks guys!
