OK so the 550 is up and running. I started with Remington brass with Winchester primers and 3.2 grains of Titegroup. I loaded 125 grain LNR of unknown manufacturer to an OAL of 1.11.
Function was great but accuracy was not and I know there were a couple of"keyhole" tears in the paper. I'm wondering if the bullet diameter of .357 was the problem? The "guy" at the store said it was fine but IDK. I'm thinking I may have to give the .357 away and find some .356. Don't know what the hell else it could be to cause keyholing.
I could use some advice. Thanks (shot thru a 92fs)
