Questions: what do you think the minimum energy and speed is of a .338 on elk and what would that translate to in distance. You may recall that with Groodgrouper the question was raised about what the limit is given his 1410 yd elk?
There is a whole book to be written on this issue. To me the biggest issue is not energy or impact velocity but in bullet placement. If you can assure perfect placement you can get by with less horsepower. I like to error to the side of caution. With the 300 SMK specifically you cannot count on the bullet expanding at longer distances it will have loads of penetration though. With this in mind it is not the energy that regulates the distance but the conditions. The conditions will regulate my ability to place the shot exactly and the distance I can do it at.

Shawn,
Just out of curiosity, what have you found as minimum fps impact speed that does cause expansion on game animals with the 300SMK? Depends on animal size and placement (bone, size of bone, no bone hit, etc.) again, but wondered if you or others here had a 'rule of thumb' that one could use initially to get a feel for this projectile. In your first video, I recall you mentioned 1600fps (with no qualifiers attached as to why) as a number you were 'comfortable' with. As someone who will likely be shooting this bullet soon, I'm trying to learn what I can about it.
Thanks,
Jon
I used 1600 with the 300 SMK because it will definately penetrate the shoulders of an elk at that velocity. Impact velocity of 1200 fps will shoot clear through a deer in most cases. Bullet expansion is not reliable but terminal performance is still good with some odd but still impressive wound channels. At these velocities there is still a cushion for plenty of penetration.
