I've been shooting and building edges for 12 years. My 285s like 3.990 coal. R33 works well. Haven't tried h1k since the r worked. Just started using Bertram 375 rum brass so I don't confuse it with my 300rum stuff. I'll post some pics and vids later if it will help. My current edge is 29" light palma with 1-9.3 twist and weighs 13lbs with scope. Also, single feed. It has never hindered me during a hunt
