As it seems we're starting to get (admittedly, far too few) some MDRs in folk's hands, I thought it might be worth starting to collect a 'what we know'/range results in a single thread.

For anyone with an MDR already, please post your results for 'what's worked best to date' and what didn't.
Right now, it seems from readr1's thread: http://bullpupforum.com/index.php?topic=12545.0
readr1: FGMM 175SMKs - ~2MOA

coldboremiracle video https://www.youtube.com/watch?v=FfpE9Ui21x0&t=5s
Hornady 155 (unsure if Amax or?): 3 shot .75MOA, +2 bringing to 2MOA
Hornady 150: 5 shot group at ~1MOA
Federal TBT 165: 5 shot group ~2MOA
DT 175gr Match: 4 shot ~.75MOA, +1 bringing it to ~1.5MOA

spector762: handloads 150g gmm seated to 2.820 with 45g of h4895 = just under or at 1MOA.  Unknown recipe and 155tmk also ~1MOA or just under - 5 shot groups

I reload, but going to start with some factory Hornady and FGMM, some random milsurp and possibly some of my lighter bolt gun 175SMK loads assuming they're not too long to chamber.

Anyone else have factory or loads/results to share?

Yeah CBM's 5x5 vid puts the MDR right at 1moa with the DTA .308 ammo.  And on ttag test they have some bad groups, forget which ammo.

Throwing this out there although was a pretty crappy session with the optic low and rearward (waiting on optic so had to pull from bolt gun - not a good cheek weld and optic too rearward).

100yd
1980s milsurp M80 ball 5 shot group - ~2MOA and a flier blowing it out. 
4 shots Amax 155gr factory ~1MOA.  Was intended to be 5 shots but was losing light and had only loaded 4 in the mag, 'good enough' until I get the optic and right mount. 

Not much to confirm or deny at this point other that it ran 80 rounds w/out issue (all ball + 4 Amax 155gr factory match) w/out issue and the mag release is stiff AF.  Will be re-shooting with a ton of factory match ammo once the new optic and mount show up.

What sizing dies are you using? Full-length I'm assuming?
