[QUOTE="a.JR, post: 30695, member: 1391"] Austin,I am sorry for confusing the issue on Pressure with my previous post as we are talking of 2 different things..The case separation issue has to do with the strength of the action /barrel not the amount pressure the case can actually withstand.i have taken the Lapua cases you talk of to way higher pressures than your useing,getting 10 loads(so far) with zero thinning/separation in the web.I even took 6 cases to destruction with up to 82gns of H4831sc with a 190 gn bullet with no change in the area you speak of(my losses were to massive case head expansion..The reason that the Lapua would fail earlier is because the bottom part of the case is a lot harder than the Win.I would look to the mechanical side of things for these failures including barrel treads ,barrel tension, and the method of head spacing..JR..Jeff Rogers [/QUOTE]
