Before I start developing loads for my Winchester Model 1895 in 30-40 Krag I would like to get an idea of how far from the end of the neck the rifling starts. The logical thing is to make a Chamber casting and meassure it. That said Midway sells a low melting temp metal for this chore. But at $19.99 + shipping I would like to find a cheaper DIY method. Can anyone see a reason a Parifin wax cast wouldn't work. I'm not looking for any critical dimentions or angles. I just want to know the distance to the rifling so I can find those bullet designs best suited for a rifle and cartridge combo known for it's long throat. If I have 2-3 rifles to do this with the metal would be a better option. But with my other rifles its just not a worry.
