I have had great results in the .250 Savage Mdl 16 that has a 1:10 twist with the Saeco 25 100 and good results also in the .25-06 mdl 700 with a 1:10 twist and the RCBS 25 120. However, both are 2 cavity moulds and with my peripheral neuropathy I was looking for a 4c in aluminum to increase the speed and reduce the weight on my hands. So I ordered a NOE 260 105 in 4 cavity. When I ordered this mould the dwg showed all driving bands to be at .260. The mould as produced drops bullets that are only .254-.255 on the first driving band. I have not been able to get my 260 105 to shoot anywhere close to the Saeco 100 in the .250 Savage. So, I called Al and discussed it with him and he said that the dwg that I ordered from was wrong and that the first driving band was to be .254-.255. He said that was the original specification sent to him by Blammer and that he would change the dwg to agree with that specification. He has since done so.
Now, he hasn't offered to refund my money, nor have I asked him to do so, because neither of us knows if that slight difference in the FDB is the reason for this designs poor performance. That's the whole story, and why I am wondering if anybody else who has this design has been able to achieve MOA accuracy at least once in a while with it. I have not tried it yet in the .25-06, but I undoubtedly will once the weather warms up!
