[QUOTE="RockyMtnMT, post: 1193977, member: 7999"] I think this may have been due to not enough stability for the mono. The mono bullets are long for their weight or light for their length. How ever you want to look at it. Either way they require more twist for good stability in terminal ballistics. If they are low on sg then they will tend to tumble and not stay on the intended path. Also may not open as they should if the point deflects at all. This is why we have been so diligent about the required minimum twist for our bullets. Marginal stability will still shoot very accurately but cause problems in terminal performance. I thought that I understood stability until we did low vel impact testing. Learned a lot. Fortunately we did our learning on test media. Hollow point bullets need hydraulics to make them open. This goes for tipped bullets as well. They are hollow point too, they just have a piece of plastic stuck in the hole. Sometimes the tip inserted into the hole can impede the expansion if the hydraulics can not get into the cavity. Our North American game animals are not as hard to kill as yours, so our guys don't see the need for what you are talking about. Keep up the good conversation. Steve [/QUOTE]
