This was originally posted in a thread about BCA .350 legend uppers, but I wanted to see if any other reloaders had been experiencing similar issues.
I recently picked up one of BCA’s .350 legend uppers when they came back in stock. I was apprehensive at first for the reasons described above, but the price was right so I thought I would give it a try.
THE GOOD: They must have made some changes in the way they leave the factory. My upper came with a shiny polished chamber and feed ramp that hasn’t had a jam or failure to feed with any ammo other than 124 XTP’s. I’ve run Win white box 145’s, Win 180 power point, Win 150 deer seasons, as well as 165 FTX reloads and 124 XTP reloads. Admittedly, the 124’s were tough to feed if I didn’t apply positive pressure to the bottom of the magazine. I believe a slight beveling at the front of the mag may fix the issue, but I don’t plan on running 124’s very often.
THE STRANGE: I’ve have had some strange pressure signs on my brass that don’t appear to have any common factor other than the rifle. All of the ammo described above had a few pieces of brass that were noticeably bulged near the case head, and some had extractor marks. This was true for both the factory ammo tested as well as the reloads. My reloads were well under max using H110 and a Lee Factory Crimp Die. Probably close to a third of the brass had to be thrown out after my last range session.
So, while I cannot complain about the reliability of the upper to “go bang,” I am concerned that there may be another issue. I plan to run about 100 rounds of the same ammo described above through my CVA Scout .350 to see if it produces any similarities. Are there any ideas on what is happening?
