Success!
This is a plain base .502 305 grain NOE bullet,no lube groove,no crimp groove. I force crimp it with Lee collet die and it holds in place @ 1640 fps from a 3" S&W 500 barrel. Three coats of TMG Gold,sized .5015 with Aqualube,BHN 14. I give it some taper crimp with a Hornady Taper Crimp die first,then Lee collet. Other dies are RCBS carbide - I use Redding for J-loads but they are very tight for cast.
Five chronoed rounds had extreme spread of 12 fps, I checked Federal 215 primers today - and will stick to them. I shoot clays on the berm @ 50 meters with this, barrel looks 4" because of the last 1" is brake.
I find it amazing that Hi Tek coating can take this violent,crushing crimp. No lead in the barrel, I have been shooting and developing load with these for a week now,about 200 and now I'm set with the load. Case full VV N110...
