[QUOTE="idaho elk hunter, post: 841832, member: 68226"] I have been approached on this a lot by several people wanting more power. I simply hand them all the manufactures sectional density's and ballistic coefficients. Let them search the true velocities that the 7mm and the 300 mags can truly be loaded to. Work the math or have them use the Hornady ballistic computer and see if they really want a 300 whiz bang over a 7mm mag. I was in a sports show in Salt Lake City a few years ago and a well respected rifle and ammo manufacture was there touting there product. They had a graph of the 30-378 loaded to the hilt with a high BC bullet vs the 7mm rem mag loaded with the same manufactures bullet(BERGER). The little 7mm mag had more at longer ranges than the big boomer. Imagine what a 7mmrum could do with a 28 to 32 in barrel with the new heavy 175 gr lrab, 180 Berger or the new 195 gr Berger coming out. If you do the research and want to spend your money wisely on these bullets and calibers I believe there would be more 7mm and 338 shooters out there. [/QUOTE]
