Sorry to resurrect this:
We have been doing more filming today and I am pretty excited about tomorrow. We have some paint that we have left in the warehouse for these tests and it is bloody perfect for seeing Pure barrel breaks!
Today we were focusing on the breech area, but still had the clear barrel on, and a brand new cutaway body, and we shot, say 200 rounds with zero discernable loading fractures, yet plenty of clear barrel breaks, with varying degrees of paint deposit in the barrel. tomorrow I am going to focus on the barrel and see if we can capture some of these instances.
The GREAT thing about renting these cameras V buying one: The guy turns up to drop off the equipment this morning and says " yea, and I had the camera upgraded to the new sensor last week, so you now have twice the resolution to play with at the same frame rates you had last time. Oh, and better light sensitivity." Yeaaaaa haaaa.
That means, come tomorrow I should be able to get the full length of the clear 14" barrel in frame, shooting at 1/500,000th second shutter speeds WITHOUT melting the barrel with the lights
But today we were filming the difference between Stock 05/06, Cure, Cure2 and "Future" bolts to see the real difference in how loading fractures can occur. We got some great footage of Ball Clipping with the old stock bolt. Captured it perfectly with the top of the bolt clipping the 2nd ball in the stack, and then this blowing up in the start of the barrel.
This is great fun
If a little messy....
