[QUOTE="Darryl Cassel, post: 27874, member: 34"] SS Which caliber you shooting? I think a standard minimum velocity of 1200 to 1450 FPS is desirable and with a minimum energy level of from 800 to 1000 Foot Pounds with good high BC bullets. This would be for the 6.5, 7mm and also the 30 and 338 bullets. I have seen MK bullets kill and expand with less then what I listed above though. Some might think the bullet was tumbling at a lessor velocity but, the exit hole in the animals that the bullet did not expand very much in was nice and round and about the size of a quarter. The MK bullets when expansion is great will be about the size of a volly ball when hit at 1000 yards and with the 338/416 Rig. Improved. At the same yardage with 7mm 168 gr MKs out of a 7/300 Weatherby or the 142 Gr MK out of the 6.5/300Weatherby will be about the size of a grapefruit. The same with a 200 gr to 220 gr MK from a 30/378. The 240 Gr MK tears a very impressive hole in game also as has been posted here last hunting season. Not sure which bullet your asking about though. We used to use the 140 Gr Hornady match bullets in our 7/300 Weatherby's and they seemed to disintigrate when shoulder hits were made on deer. The jackets were VERY thin on the Hornady match bullets at that time. I would not use them on elk at all. Later DC [/QUOTE]
