The Truncated cones I used needed to be sized kinda short, at least that is what I had experienced… I used Berry's 147g TCFP (plated) I had it sized to 1.100 and they wouldn’t plunk in any of my barrels except in my Canik TP9 sfx. I had to get them down to 1.090 before it started to plunk in the rest of them. I have since moved to a rounded with flat point in a coated like ibejiheads, Precision Bullets, I just ordered some from Everglades in a plated. I want to see how those will work..
Knob Creek I have some you’re welcome to try and see how they work before you waste your money…. Let me know….
