I bought some and there is more on SPS as seconds. I'm wondering how it compares to WW for durability. I have a bunch of RWS but I know I'm giving up some velocity using it in my 7-300wm and 6.5-300wm. The stuff is so tough it's ridiculous but it would be nice to have another 100fps too. I'll probably build another 6.5-300wm with a 32" 1.25" barrel and it would be cool to go over 3400fps with 140's in it with the Retumbo load I use now and maybe push 3500fps with R-33. Right now my Retumbo load is doing 3225fps and the R-33 load is doing 3290fps in a 28" barrel with RWS brass.
