Hi All:
This makes the 2nd time in the last week someone has claimed that the 338 has a better selection of bullets. The 35 Whelen can shoot varmints with the 110, 125, and 140 grain pistol bullets. Deer can be shot with 150, or 180 grain, or 200. Elk and Moose can be shoot with either 200, 225 or 250. I actually prefer the 200 on Deer and the 250 on the bigger stuff. In case you're going to be in grizzly or polar beer contron Swift makes a 280 and Woodleigh makes a 310. I think if you take a closer look the next time your at one of the bigger places like Sportsmans Warehouse of Cabela's you'll find almost twice as many offerings in 35 than you will in 338.
While I could spend a lot of time making a case for my next supposition. I'm really going to try hard to let you all do that research for yourselfs.
Rule #1 The best penetration on game animals with all most all calibers and all bullet weights comes when the impact velocity is between 2,400 fps and 2,150 fps. Note that this rule doesn't apply to varminting.
If rule #1 is followed you have an exit wound most of the time. A good exit wound is the best way I know to make the big game go down fast.
Rule #2 The other factor in making game go down fast is the diameter of the permanent wound channel, or bore diameter.
Given my rules: The 35 Whelen wins in almost every situation. And does so with less recoil and muszzle blast
Try this little experiment. Take the velocity of a 250 grain Whelen bullet at 300 yards and the velocity of a 250 gran 338 Win Mag bullet at 300 yards and figure out how many grains of powder were burned per foot-pound of energy. Very enlighening to say the least.
