I have been reading about the 6.5 Super LR round on 6ar.com for a while now. I am currently shooting a 260 Rem for 600 & 1000 F class matches. I started using Lapua brass which works well, but is pricey. Then I tried some Winchester 243 brass necked up that is starting to become more widely available. It seems to work very well as well, although the cases may not last as long. After reading that I could use the Win 243 brass and form the 6.5 SLR brass in a single pass and avoid the dreaded doughnut: I am interested in any thoughts on this round. It seems to fill a niche with it's 30 degree shoulder, good case capacity, long neck and reasonable barrel life. The only downside that I can see is die availability. Although it looks like I can get die sets from Whidden as well as the Redding sets offered by 6ar.com.
