Here is a link to a custom search feature for the 6.5 Grendel forum. Do a search as there should be threads discussing PTG reamers.

Trilogymac, the short version of the story is that there is considerable bad blood between PTG and quite a few people, on this forum and others.
1) It is thought that PTG made faulty Grendel reamers that in turn produced a bunch of defective (short-throated) barrels.
2) The owner of PTG stated that he did not like the Grendel's compound-throat design, an opinion that went over "like a fart in a scuba tank" on this forum.
3). For a while, PTG made a "6.5 Grendel II" chamber that had a traditional throat rather than the more complicated compound-throat used with the SAAMI Grendel.
4) PTG's site claimed their chamber was better, which is questionable at best. The PTG website no longer offers it, make of that what you will.
I had managed to forget about the PTG "Grendel II" (non-compound taper throat) brou-haha and the short-throated Liberty and Stoner barrels in 2014. I find this particularly sad because I now remember that I had even started a thread about SAAMI Grendel vs Grendel II loads. (I was Nincomp back then...the forum hack ate my old screen name).
