Making a new load for a rifle with a new set of Hornady custom grade dies in 6.5CM. Not the best, but I was able to find them in stock.
On my first 25 rounds I have over .010 of variance between cartridge length measured from the OGIVE.
My die is set up as the instructions say in a single stage RCBS. I’m using the correct shell holder, and primers are seated fully. The projectiles themselves are pretty consistent when measured and the brass is brand new and sized. Finally, it doesn’t seem like the tip of the 140gn BTHP
is hitting the seating stem at all.
Any ideas or help? I talked to Hornady and they didn’t have anything else to try.
