This is a design I've heard nothing about, except for a few who really like it. I am seeing two distinct versions. One is the Lyman solid, which appears to cast too small. The other a Hornady hollow base which has mixed reviews. My 54 caliber really likes a maxiball which is .550" on the top band and .540" on the bottom two. In particular I am interested in the Accurate molds 55-430M, with the same dimensions. My concern with the maxiball is that the design looks like it would mediocre for hunting, at least for the recoil you have to endure to shoot it. This great plains style looks to me like it would work great, assuming it would shoot good. Are any of these great plains bullets worth trying?
