sabotloader : check out tradition web site,go to closeout items ,you will see the keith nose HP in the green sabot in 350 grains.I can tell you they easy to load in my t/c hawkens 50 cal. flinter and shoot great.I did purchase them off the tradition web site last year. I tried the Hornady SST and the xtp mag 240 grain,they will load in a clean barrel, after the shot the second one is a nitemare to get down the barrel,I won't try them at all.I found that thr REAL 320 grain conical and the keth HP 350 grainers shoot the same pattern with 85 grains of goex 3f.
