No disrespect intended but I would never do this. Never shoot a round when you think there may be some safety related issues involved. That's not the smart way to check things out. Figure out and solve the issue before firing.
EDIT: Just remembered I have IMR4064 and 30-06 brass on hand. For unsized brass after firing in a M1 Garand at 2.484" in case length I get 54 gr of 4064 at the top of the shoulder and a completely full case is at 61.5 gr. This is for filling with a Lee dipper, with a drop tube you could get a little more in. </div></div>
I did the water check and the cases hold 68g of water. understanding water has a different weight and no air I still figure at that volume the difference can't be more that a few grains....so I pressed fwd with the assumption I was just dumping powder very loosely. Shaking/tapping the case down a slight bit makes room for the max load now...I can fit about 59g and load it....
Thanks for all the help, but now I have to question the 50g I loaded being too little.
<span style="color: #3366FF">I load 110g Speer HP's at 50g which is .5 ABOVE the min load. so thats where I figured to standardize my 110g rounds at 50g...Figured externally the only difference between the speer and vmax was a ballistic tip so why should that change the charge?</span>
Any thoughts?

The Speer .308, 110gr Varminter JHP bullets, part #1986?
My #13 Speer manual does not list IMR 4064 with that bullet, for the 30'06.
I'm sure it would be close, as they do list IMR 4350, IMR 3031, IMR 4895 and IMR 4227, but not IMR 4064.
