30% more powder in a 7MM to do the same thing as an 06.
I was basing my comparison on the Max Load values from my reloading manuals. The highest 06 chargeI found was 64 grains MRP and the largest 7 MM Remmington charge I found was 82.5 H870. 64 x 1.30 = 83.2. Maybe a teeny streach but I was alway taught to round up.
When making comparisons about case capacity at least use the same powder to compare the 2 rounds. There are very real differences in volume of different powders which leads me to think that you probably don't handload. Getting back to your 06 vs 7mag post I think you take way too much magazine and brochure ballistic data as gospel. The reality is that a 7 mag will shoot a bit flatter, have a bit more energy (especially at longer ranges) and penetrate as deep as a similar 30 cal bullet in the 3006. Is the difference drastic? No its not but the same can be said of a .270-.280-30-06 and yet they all have thier fans. Enjoy your 3006, it will handle everything you are likely to hunt but stop trying to validate your preference by knocking the 7mm mag.
