I have my bbl. throated for the 150 SMK for optimal bullet placement in the neck. The bearing surface is so much longer with the ELD-M that it would clearly be into the powder collumn. after the throat has eroded somewhat, I'll give them a whirl.Why not try the 147’s for Hornady? I have asked before about their other products and the common response was the quality control was not good enough, is this still the case for the eld-m (new a-max)?
I hope this helps,
Lloyd
