I had two (2) 7mm Sherman Short Mag barrels about a year and 1/2 ago. They shot GREAT, however, they ate up my 2 Krieger barrels like a kid on Halloween night eats candy! It kind of "hacked me off" and I gave up on the cartridge. I missed the Sherman and wanted one again. Sooooo I ordered a 8.75T, 4 groove conventional barrel made out of Bartlein's "new" barrel steel offering. I had it chambered up and started to break it in, while creating some initial load development. I started with the first rounds down the barrel at 100 yards. I started by shooting 10 round groups and almost all of them stayed in the .200s! Well this may very well be a shooter. ZOOM up to today... I took it to a 500 yard match at Rio Salado in Arizona. My friend John Farraggio (Cognac Jack) on this forum, shot the rifle today for me, as I needed to shoot a .300WSM that has not been shot in months. I wanted John to keep a close eye on the vertical dispersion. Well John won the match with my rifle and said that the vertical was so close to the waterline, making a gesture using his thumb and index finger, indicating barely over an inch of vertical dispersion. So now we KNOW the barrel will shoot>>> but I wanted to see how the throat was holding up. I scrubbed it to the bone and ran a bore scope in there. WOW! Low and behold there was not even a "HINT" of the preliminary steel discoloration that shows up prior to firecracking raising it's ugly head! To me, this is an excellent indicator that the "special steel" Bartlein uses may very well be what their claim / intent is! Their barrel is a bit on the "pricey" side. However, if it proves to have the longevity it is supposed to have, it will actually be a MONEY SAVER! The cost of 1 less barrel to chamber, about $100.00 cheaper than 2 full priced barrels and no components to break in and do load development with in a second barrel! It is still very early to draw any conclusions, however, ZERO barrel discoloration with over 400 rounds on an "over bore magnum" is quite promising!
