I am having trouble finding CBs for my K31. The 174gr Lymans I have cast for my 20-06 and 30-40 will not wok. First, the bore ridding section of the bullet will not enter the bore, so I need a front end smaller than .295. Secondly, the rifling begins about .010 or so in front of the case mouth, this means I need a short groove diameter section and a long bore riding section as I do not want the base and gas check any lower than the base of the case neck.
Are there any standard molds that will cast the bullet I need in the 150 to 200 grain range?
