    Hey nice video but there is a caveat,
    I researched reduced loads for testing several years ago and found through Wayne Van Zwoll that the reduced loads also reduce RPM and RPM's play a major role in the centrifugal force that helps bullets open on impact. It was shown that although bullets slow down predictably over long ranges, they actually maintain most of their RPM's that's generated from the barrel twist. Wayne showed through testing that all bullets expand much less when started slower vs std. velocity impacts at long range with same velocity as the reduced loads shot close. Take care

      If it made a senifacant difference subsonic rounds wouldn't work and guns like the 300 AAC/Blackout would not exist as they shoot the same bullet grain weights with the same twist rate as 300 PRC's. Here is a video that shows that 80,000 RPM's made no real difference. Also I was in contact with nearly all the major bullet manufacturers in the US and they told me I could test in this fashion and most of them use a similar form of testing to give velocity ratings for their bullets.

      @@simplemindedfella Your reduced velocity loads do NOT simulate what happens at long range. The gyroscopic stability of a bullet that starts at much higher velocity is completely different. The tumbling occurs because the bullet is unstable or nearly unstable at such low muzzle velocities. The only sensible way to test expansion at lower velocity is shooting at distance. If don't want to shoot too far you must ensure that the bullet is stable at reasonably reduced muzzle velocity. In fact, rounds like the 300 AAC BLK do have much faster twist rate at 1:8" or even faster at 1:7".

      @p.r.8049 and that is why I have 1:8 and 1:7 twist barrels for most of my low velocity testing. I also have videos on the twist/RPM differences at both high and low velocities, showing those differences and the actual effects, not just going off theories.

    Thank you. Great upper end results. Good data for our community.

    Great video, they kill deer like a bolt of lightening, very accurate in my Krieger 308 bbl with, R#15, 8208, Varget, and IMR 4064. I love how you do not talk about a lot of BS, staying on task!

    Can you try 180 e-tip on a 300 wm?

      If I am able to get my hands on a few. I am wanting to do a series on 30 cal monolithic bullets like I have on 6.5 just having trouble getting what I need at the moment.
