When I first got into long range shooting/not hunting, I quickly moved up the horsepower ladder , did the 300WM with a 208 A max and concluded with a 338 Lapua.
The recoil and powder consumption penalty was simply too much for me.
Now I settled on the 243, 224 & 264 calibers... I do miss the impact of those big calibers though... the 224's are fun but have serious disadvantages, such as spotting misses,
the impact is simply too small unless you have a fine dry dirt bank behind the target.
I would never fault a guy for wanting a 300 mag , especially for hunting!
