It has worked for me. When I got into casting, I had one goal; I wanted to shoot cast bullets at jacketed bullet velocities or better while maintaining my accuracy and killing authority expectations (or I would stick with jacketed bullets). The first rifle I worked with was the 444 Marlin, a cartridge that can actually stretch the limits of cast bullet performance. I did not see any mold designs that actually fit the Marlin, so I designed my own (rather crudely compared to how I do it now). I decided to Micro Band it rather than arbitrarily use the traditional grooves. The bands, along with Alox, worked like a charm. Since that time, everything that I shoot uses the Micro Bands and Alox.Zippidydoodah wrote:RD, do you find micro grooving to provide better gas seal on all cast design bullets, and would a hybrid micro rear grooves be helpful on conventional BP bullet?
I have deviated from the Micro Bands twice, 30-30 Win and 38-55 Win designs, using a Lyman 4500 and various other lubes. The best lube I used was 2500+ but it still did not equal what I've seen from Alox. Hands down I prefer the Micro Bands and Alox. I dip most bullets rather than tumble, less mess, and never have I had a bullet not meet my original goal expectations (32 different bullet designs).
