I thought you were saying the longer 300's create a better gas seal, elevating barrel pressures and would therefor show greater velocity from the same sabot/charge combination.
No that was not my point, what I was trying to do was to comparethe velocity of the "Test Sabot" to the other sabots that I had on hand. The goal was to see if there was a significant velocity/accuracy difference between the 24's and the "Test Sabot" (HPH-3p-EZ) - which there really wasn't. With out the rest of the test targets and the written report to MMP it really does not make a lot of sense.
What would you say if you put the 200's thru a chrono from the White and found 2000+ fps? Still wobbling? I think so, but not because they aren't spinning fast enough but because they are being pushed too hard. Faster than the spin rate can stabalize. Just a thought. Suppose you took the White again and used 80 T7??
I am always interested in experimenting - so when I get a chance I'll do that... it could be... but if it were to be true(reducing the velocity)there would be no sense in my mind to shoot that bullet, except at ground squirrels.
If the darn weather would cool off and the fire danger would go down I would do a lot more shooting....
