Hey guys, have a favor to ask of other MSR10 owners. Specifically, those with rifles chambered in 6.5CM if possible.
I've got an issue with bullets unseating when chambered. Bullets start at OAL of 2.790 and come out of chamber at 2.82-2.84 by doing one of three things:
Here's what I'm hoping you can do to test:
Should only take 3-5min and could help out a bunch of other MSR10 owners of their is an issue with spring strength and BCG speed.
Thanks in advance!
I've got an issue with bullets unseating when chambered. Bullets start at OAL of 2.790 and come out of chamber at 2.82-2.84 by doing one of three things:
- Chamber round from magazine by releasing bolt stop
- Chambering round from magazine by manually cycling bolt with charging handle (full rack)
- Chamber round by firing and letting auto feed next round (normal fire)
Here's what I'm hoping you can do to test:
- Use your normal resizing process on 3 pieces of brass. Write down neck diameter after sizing and neck thickness.
- Load bullet (no primer no powder) at your normal seating depth.
- Measure and right down each exact OAL for each bullet/case, loaded neck diameter.
- Load those three dummy rounds into magazine
- First round, chamber using bolt catch release
- Second and third manually cycle aggressively to simulate firing.
- Measure all three rounds OAL afterwards.
Should only take 3-5min and could help out a bunch of other MSR10 owners of their is an issue with spring strength and BCG speed.
Thanks in advance!
