Getting ready to start my first load development with the 129 ABLR. Has anyone experienced better precision/groups using VLD vs. standard inside chamfer?
Chamfer for ABLR

Never tried the VLD chamfer, I just use the one on the RCBS case prep tool or like I used for years a countersink. Easily got sub mOA loads from ABLR loads.
I did use some accuglass bedding compound with a bullet to make the seeting stem match the bullet profile.

65GBY,
I have a few of these tools but mainly use a hand-held VLD chamfer once only on new brass. Unless using bulk cases for plinking and that gets the Lyman tool in a power drill, again, once only.
I don't imagine the angle on your chamfer is going to make any difference to accuracy, and even if it did it would be so minute that you wouldn't notice it. There are way more influential variables affecting group size. As long as the chamfer is square to the case so when the bullet shank clears the neck gas is not favoring one side.
