Thanks for the help guys. That’s why I came here. After reading some of your comments I have done some of the trouble shooting you guys mentioned. I remeasured my gun with the OAL Gauge and the vmax. I still come up with 1.931.5 as an average. But, I might have Misread my OAL Gauge when combined with the comparator. I didn’t zero it out after adding the head space comparator on it. When I did this I got a lower number. I now have 1.889.5 as an average on the rounds. This length does fit in all of my mags.
As far as the dies go, I did a full length resize on them and I didn’t change anything on the die when I switched from 223 to 5.56.
I did try some test loading on just the cases. I did empty 223 and 5.56 cases. Didn’t have any real issues with either. A tiny bit stiff but nothing like what I have to do with the Vmax rounds.
Ok sounds like you are getting closer. I would suggest you forget the OAL gauge and only worry about the OAL of the complete cartridge which is the dimension from the tip of the bullet to the bottom of the brass case. The OAL for the case with the Vmax bullet needs to be in the 2.2 inch range I load a 69 grain sierra to 2.23 and it chambers ok. So you need to seat your Vmax bullet deeper and you should be good to go.
Here is a pix that shows where the OAL is measured.
The dies that you use do they use a small base resizing die? A lot of guys that reload for semi autos use a small base die to make sure the brass will chamber in any gun they are shot in. Hornady and RCBS make die sets with a small base resizing die. The Hornady set item #564228 has a seating die which has a floating sleeve which helps to hold the bullet in alignment with the case better. Not telling you to go out and buy a set of dies just curious as to what you use. Keep us posted on your progress.
