[QUOTE="Darryl Cassel, post: 52013, member: 34"] Hello to all. I wanted to get my 2 cents in here too. JonA On the ballistics you gave for the 180 gr (3450FPS) and the 240 (2950 fps) Heres what my Oehler program with a graph printout shows. Energy level at 100 yards (stating out) 180 gr---4223 FP 240 gr---4824 FP At 1000 yards 180gr---1790 FPS---1281 FP 240 Gr--1764 FPS---1654 FP At 1100 yards 180 Gr--1659 FPS--1100 FP 240 Gr--1665 FPS--1478 FP At 1200 yards 180 gr--1536 FPS--944 FP 240 gr--1571 FPS--1316 FP Clearly the 240 is the superior bullet as per energy and it catches the 180 at a tad less then 1100 yards. As per the velocity in "longer" barrels. I get 3150 FPS and 3200 FPS(50 degrees) with my Tomahawk and a 34" barrel and with the 240 gr bullet. I'm not sure if you were refering to 34" barrels when you mentioned "Longer Barrels". Now program that speed against the 180 gr at 3450 and you will find that the 240 will catch the 180 at 500 yards. If I were a short range hunter and hunted big game such as elk, I would want the superior bullet which is the 240 at ANY range I hunted. For smaller game like deer the 180 would be fine. For longrange and above 500 yards, I would use the 240 everytime. It's hard to match up a bullet with a BC of only .540 (180 Gr) to one that has a .711 BC (240) Another interesting fact is, the time of flight in your scenerio is 1.2 Seconds at 1000 yards for either bullet and 1.5 Seconds for both too at 1200 yards. I'll take the 240 any day, but then again, that's a longrange hunter's point of view. Higher BC bullets will retain their velocity and energy level MUCH better then the lighter lower BC bullets will at almost any range. The Tomahawk is an improved 300 RUM with a 35 degree shoulder that holds about 8 grs more powder. Boyd has a 36" barreled 300 RUM that I am quite sure he will get 3100 FPS with the 240 gr. He "won't" beat the Tomahawk even though I have 2" less barrel. [img]images/icons/grin.gif[/img] Later DC [img]images/icons/smile.gif[/img] [ 06-13-2002: Message edited by: Darryl Cassel ] [/QUOTE]
