Bingo!!!! Just hung up the phone with Dave at PTG. (Pacific Tool and Gauge) They made the reamer for the Grendel that McGowen used on our barrels. Dave stated that the Grendel reamers are made to SAMMI specs but the specs drawings are wrong in his opinion. To tight of tolerance. Dave also stated that he has heard of many many case of bullets being torn from the case when this reamer is used. When the barrel throat gets just the slightest of carbon fouling in it the bullet sticks. As soon as I said Grendel reamer Dave new exactly what I was talking about. The Grendel is a double throated reamer and he said to use a .264 LBC reamer and that reamer works just fine and much better with the Hornady Grendel ammo because this reamer uses a parallel throat. *Dave also stated that one could use a uni throat reamer and that reamer would open the throat a bit and probably solve the problem I am having.
This whole subject is way over my head and I am trying to gather info in order to solve the problem of rounds sticking on these Grendel barrels I have purchased. I hope I am on target with this post and if not please correct me.
