[QUOTE="buckbrush, post: 2487877, member: 13680"] If there was solid and consistent data/performance data for these wildcats there wouldn’t be such polarizing contention when pressure and velocity discussions surface. Rather, concerns over pressure and not being able to obtain advertised velocities result in banning from FB pages and pile-ons from those who experience acute post purchase rationalization. People seem to have been conditioned to believe that traditional pressure signs are to be ignored when shooting these wildcats. Many claims of “you need to be an experienced wildcatter” to make these work are tossed around. This thought process doesn’t align with even rudimentary physics lessons, but whatever. Sherman wildcats should get some credit for changing the paradigm about cartridge design…slightly. It’s been the trend in the market for the last 15-ish years. If it weren’t for people Iike this guy, we’d all still be shooting 308s and 30-06s. But “know your limitations”. The designer’s credibility is suspect to me and others. No published load data except for a spreadsheet created by someone who isn’t pushing/drawing these cartridges. And there certainly isn’t pressure data on this spreadsheet. It’s subjective “bolt lift”, “ejector swipe” notes. If primer pockets are loose, bolts locked shut, etc. after hitting advertised velocities, the blame game begins…as previously stated. Or, temper tantrum, finger pointing behavior in public forums ensues. Why not assume some professional behavior and just stop recommending Proof barrels? Even if all of the “investigative research” that’s has been performed suggest that there is indeed some voodoo that occurs when a Sherman reamer touches Proof steel. Rant off. Toodles. 😁 [/QUOTE]
