Looks for Range (1/11)

  1. Stock recoil spring 16#. Is there a reliability benefit to a heavier or lighter spring? Tried different OAL which produced different shoulders. 230g FMJ's were reloads. Will try 1.250 with a heavier crimp.
  2. I have a Springfield TRP that I just recently started loading 200g SWC from Bulletworks. I'm using Federal cases and 5g WST. TRP is about three years old with never an issue in ~8k 230g FMJ. TRP is completely stock. When the round is stripped from the mag, the nose impacts the feed ramp and the bevel portion of the throat at 6 o-clock. The bullet has an obvious impact mark on the leading nose edge where it impacts. Directly below that and on the case, the case is impacting, something, and creating a crease. I don't believe it is the throat because it is a straight crease and I would have anticipated a curved line based on the angle the case would still be engaging with the ramp/throat. OAL less than 1.245 and I was getting three point failure to feed, where nose of bullet is hitting the top of the chamber, followed by shoulder and then bottom portion of the case. At about 1.265 or longer, I'm not flush with the barrel hood. OAL at about 1.255 and it isn't as noticeable. Magazines are Wilson 47D, but also tried it in the standard 7rd CM's. It is more pronounced on the first couple rounds in a full mag with the Wilsons and the first rd in the CM's. Anyone run into this before and what was the solution? Is this a magazine problem? Thanks in advance!
