This was shot with the Geissele super duty.

Having this amazingly accurate rifle with a 4-16 scope helps a lot. Makes me wonder how many AR's we all have that shoot lights out but they sport Aimpoints so we really never know how accurate the rifles are??
We had a couple popped primers but not like weeks before and Mark loaded a FAT tray of nice 556 ammo that was a C hair too long to fit in AR's but ran nicely in the 5R bolt gun. Mark but he was fkn pissed about the long ammo, LOL. Hey any 556 ammo is good 556 ammo, there is always work to get done!

Retested the 22.3 gr TAC, Fed AR Match primer combo, and it's the final load for sure. Great accuracy, and no popped primers.
It still amazes me how big of an impact the primer can have on a load.
Revisiting these heavies with a box of Barnes Factory ammo inbound. And also adding the Nosler 85gr RDF bullet to the research.
Lord this topic is popular! :sarcastic:
I loaded some head to head tests, Match Burner vs. RDF with Both TAC (a new lot) and VV135. The RDF is a VERY 'pointy' bullet requiring a dramatic adjustment on the seating die to get it to mag length. I wish I could haul my loading set up out to the range and finish load work up in one day, but we'll see what happens.
Wow are these RDFs impressive. Will definitely work AR Mag length, which I was worried about.
I'm still working up a load with N135 so my velocities are still modest.
But we shot the RDFs against factory, hot Barnes Match burners which were over 2700 out of a Tikka 23.75 inch barrel. RDFs were just over 2600, but were about a Mil flatter at 1000 yards.
Still just getting started with the development/safe pressure, but looks really promising.
I probably have a arbor seating die, but there's no solid surfaces to set up a scale and press at our spot.
