Got the hornady shell holder, it is made much more precise than the rcbs, as far as the case fitting into it. Still i had some tight cases,: so: contacted hornady tech, he said: since i was using a press that had a dead stop and did not cam over, that i would probably need to have the shell holder ground. he warned though not to go anymore than 5 thou. I did so, and it pretty much solved my problem. been using hornady one shot spray and i dont like it, cases are too hard to size and i have stuck 2 so far as well as i can see the necks maybe stretching and possible being out of alignment too. went back to the pad with lee resizing lube and it is nearly effortless. [ has to be better] Just havent had a chance to check run out yet. thanks for all the good advice.
