River Rat,I have been going thriugh the same process, so far the 200gr Shock Wave which has a BC of .269 and the same sectional density as a 300gr 45 cal bullet is the only one that has impressed me for over 150 yds; Part of it is that it seems to shoot very accurate and once the rigjht load is found it is usally a heavy load which is excellant if you have the accuracy. Let me know if you find anything that is reasonably comparable. Lee
