[QUOTE="BrentM, post: 2678459, member: 61747"] IMHO, I see zero benefit in a 6.5 PRC in a longer action unless you are using a powder with massive kernels that is overfilling the case and compressing the charge. I also do not buy into seating any of todays bullets to the lands or close to it. Now, a PRC at 2.8 coal vs a 2.950 is different story if that is your goal, however, the PRC in SAAMI form is not 2.8. I have not tested this myself but let's say you go medium or long action and run the bullet .100 thou further out in a PRC. What is the netted case capacity gain? How many grains of powder does that equal in volume? What is the increase in FPS or net effect of increased performance? When doing a seating depth test with a 6.5-284 running to the lands and seating back to .175 thou I saw no benefit in performance in gained or loss of FPS. In the PRC I run mine to mag length of 2.950 coal and send it. Zero issues getting FPS and accuracy is that appears to be right in line with any action length. The one test I could do is single feed and play with the process but I am not convinced it is going to net anything meaningful. [/QUOTE]
