I've been trying to get on the NOE website for a couple of hours now. Looks like it's down.
The .177 and .20 cal are in the works.... The .20 cal will be the same lengths, diameters scaled up to .20 cal, and weight 19-20 gr.... Tooling not done yet....He is currently working on a .224 cal BBT, and the plan is to also produce a flat base version (0.090" shorter, no boattail, about 31-34 gr.).... Tooling done.... HP available too....Bob
