[QUOTE="AZShooter, post: 462875, member: 5219"] I cannot comment on the rifle you intend for the build. An alternative built on the 243 case is the 6mm Super LR. There is no fireforming, the die alters the brass's final shape. This design moves the shoulder down shaping it to a 30 degree angle and it lengthens the neck. Both the 243 AI and the 6mm SLR should extend barrel life. The reason is placing the vortex center of the hot gasses inside the neck instead of in the chamber. You can read about this design here: [url=http://www.6mmar.com/Super_LR.html]Super LR[/url] You can also read a ton of reports on it within 6mmBR.com in the forums section under the title: 6PPC, 6-6.5x47, 6XC, 6 Rem, 243, 6-284 Even if you don't use the SLR design and go with the 243 AI you can read about bullets/loads/performance. I am reading good things about the 87 gr V-max for varminting. With a 1 in 8 twist you can shoot up to 108s easily and it may even stabilize the 115s. [/QUOTE]
