After doing the initial 200 yard comparison test on Nov 8, I made the following recommendations:
a.  No crimp
b.  Winchester LR primers first choice
c.  Remington 9 1/2 second
d.  CCI BR-2
e.  CCI 200
f.  Federal GM210M Last choice

I followed that test up with another 200 yard test on Dec 13 and have verified several conclusions but have changed which primer I believe gave me the best results:
a.  No crimp.  The second test validated in glaring Technicolor that in my rifle using a crimp significantly increases vertical stringing.
b. Remington 9 1/2 primer gave the best performance of both tests combined.
c. CCI BR-2 second
d. CCI 200 third
e. Federal GM210M fourth
f.  Winchester Large Rifle last place

At first glance some of you may take issue with my conclusions since WLR went from first place to last.  The reason was my conclusion was based on a combination of how the primer performed in a crimped and also a non-crimped cartridge.  Now however I've decided to discard all the data obtained from the crimped cartridges.  The performance is so poor as not to be relevant.  So, using just the non-crimped cartridge performance the Remington is the clear winner.  Here are the groups from Nov 8 and Dec 13:

Based on how difficult the sighting system on the ladder sight is to use, I fully accept that the lone high shot in each group is my fault and not the load's.
