Has anyone heard of or worked with a 416 WSM? This would simply be a 300 WSM necked up to .416 with a slight reduction in case length to account for the shortening effect of the neck expansion. COL could go to 3.1" to match current magazine length in the Winchester short actions.
The case would hold 66 grains of water with a 300 gr Hawk Bullet, delivering over 2700 fps and 5000 FPE at 65,000 psi. AA 2230 would do the trick, without compression.
A deep seated 400 gr Hornady or the like would still leave 52.5 water grains of usable capacity, delivering 2230 fps and 4425 FPE.
Best of all, these velocities are all readily achievable from a 20 inch bbl.
These sound like big numbers, but they are very reasonable. I have worked with the 416 Rem Mag for over 10 years, and driven buckets of 300 gr Hawks 2950 fps using R15 with no pressure problems from a 22 inch bbl. The loss in case capacity going to the WSM works out to a modest 8% drop in velocity when the 3% increase in efficiency is added for the short, fat case.
The 300 gr .416 bullet has the same SD as the 165 gr .308 (.248)and is a legitimate 300 yard proposition. Reduced 300 gr loads will duplicate the 375 H&H at 2550 fps with less recoil. The 400 grainers have a SD of .330 and a TKO of 141, 41% higher than the 375.
The 416 WSM has the same case capacity to bore ratio as the 458 Win Mag, which thrives on AA2230 with no load compression. My 22 inch 458 drives 500 grain bullets over 2200 fps with no pressure problems using 2230.
Hawk can build custom 250 gr HPs with an SD of .207 for reduced loads for deer, mimicking the 375 with 210 to 235 grainers.
Dressed out, the associated rifle would qualify as a "Super Scout" with a forward mounted scope and even an 18.5 inch bbl threaded for a removable brake.
Anybody want one of these? I do!!
