[QUOTE="Long Time Long Ranger, post: 217938, member: 505"] That 340 wby is a great cartridge and I can't understand why it never took off and the 338 ultra is all of a suddun a world beater. Just not much difference performance wise and we have had the 340 for over 40 years. I remember when 7828 powder came out it really turned on my 340 for long range elk shooting the 250 gameking at 3020 fps. At that time it was the highest BC bullet I could get. 30 years ago that was a very impressive load for elk. I know mine impressed a few! The ultra will definitely outperform it but not by much when your talking about that much power. Lightvarmint, Looks like your loads are right in the range. What length barrel are you shooting in your ultramag? My personal 338-300 ultramags shoot the 200 grain ballistic tips at 3350 fps with a 28" barrel and that is a very definite max load with about three shots per brass. [/QUOTE]
