[QUOTE="Fiftydriver, post: 60042, member: 10"] Brian B, My comment about the 30-378 was only referring to the price of brass and what you get for your money. The 30-378 will outperform the Warbird and do it with slightly cheaper brass but my point was, much better quality Norma brass. I totally agree that in a 26" barrel, anything including the 300 RUM and larger is really to much case for the appropriate powders to be used. Now bump up to a 28" barrel and the RUM and Warbird will start running hard, as will the 30-338 Lapua. Get a 30" barrel and the 30-378 comes into its own as it can actually put that 120 gr case capacity to use. I have run my old 300 RUM side by side to a 30-378 Sako, both with 26" barrels. Both loaded to top acceptible pressure levels meaning that the addition of two more grains would start openin gup primer pockets on each load. Both used the 180 gr Ballistic Silvetip. The 30-378 churned up 3490 fps, the 300 RUM hit 3420 fps. That was like you said with 15 grains less powder. Velocity, like sex, SELLS!!! Lazzeroni knows this very well, thats the only reason he is in business still. I see this nearly every day taking with customers about my Allen Magnums. Especially the 257 AM. I tell them that it will drive the 130 gr Bonded Core FBHP with its B.C. of .550 to an honest 3650 fps and they just look at you. Tell them it will drive a 115 gr ballistic tip to 3800 or a 100 gr BCFBHP to near 4100 fps and they light up like a christmas tree. I will show them the pencil length 156 gr ULD rebated boattails for teh 257 AM with their B.C. of .820 and they simply ask how fast will it go. When I reply in the 3200 to 3300 fps range they just look at me and reply big deal, my 300 Win Mag will drive a 150 gr pill faster then that. At that point I know if they are going to compare a .820 B.C. bullet at 3300 fps to a .420 B.C. bullet at the same velocity, it will just be a waste of their time and mine as well to try to show them the advantages of a fast moving extremely high B.C. bullet. Again, velocity sells like hotcakes and out to 500 yards extreme velocity does work well I will admit as long as the bullet will handle the strains. Problem is, many extreme velocity rounds will not reach the grade for extreme range accuracy. I am with you, far to many get hung up on velocity these days. Good Shooting!!! Kirby Allen(50) [/QUOTE]
