[QUOTE="royinidaho, post: 248426, member: 2011"] I tend to agree with Bryan based on my personal expansion tests. Testing at close range, with long range velocities, with several brands of bullets which opened properly and penetrated in a straight line distance into the media was as bullet perfromance was as expected. Bullets that were of insufficient velocity and/or suspected improper design immediately yawed upon media entrance, seemed to maintain that orientation through out their travel, did not travel in a straight line, and passed much further into the media. I can only suppose that the initial wound cavity with these bullets was much smaller than that of the bullets that performed properly. The next step in my expansion testing is to connect the RSI device to the media container to determine variations in "shock" or what ever that measurement reveals. What I have proven to myself is that SMKs need at least, if not a little more, than the 1800 FPS published FPS when launched at a 900 yd velocity. [U]Maybe[/U] if launched at say 2700 FPS w/the media at 1K, the resulting increased RPM would make a bit of a difference on the bullet's ability more properly perform terminally in my media? [/QUOTE]
