I shot some 10mm 200 grain XTP's this morning from one of my Remingtons. One of the last things I did was to shoot some quartzite rocks resting on some stumps... I shot both 250 grain Speers and 200 grain XTP's (BC of .199). The way they broke the rocks they certainlt will break shoulder bones no problem...

Thanks Sabotloader,is the 250 SW about the same? Lee

I wouldn't think so because the length/Diameter ratio will change the 45 caliber ballistics quicky - usually for the negative.

Here is the information from Hornady... It really isn't that good only slightly better than the Speer 250 grain Gold Dot (BC .199)and less than the 300 (BC .232)grain Gold Dot.

SST .452 - 250 grain BC .210 ( I really thought it would be higher)

Thanks Sabotloader,I have some of the new bonded Shock Waves, after my Boar hunt in May I think I might do a bit of experementing myself.
Right now I am trying to get sighted in but we have had two friends died and one realative is going to so its been hard to get away to the range, I am tryingbetween trips. Lee
