This ammo clocked around 2,770 fps on a cool day, pretty close to the advertised 2,800 fps, and I imagine the Woodleigh bullet should work much like a NOS would. The HE load with TBBC bullets should be even better, but I haven't found any around here.
My choice for elk hunting at longer than 150 yards would be a 230 grain Winchester Failsafe or 225 grain Swift A Frame. Even the 210 NP is an great option.
I would be nervous shooting Woodleigh's at high velocity.

Some on this board, including self, have shot them at modern velocities in English calibers designed for big game at 2100 and we pushed them with modern powders at 2600, they worked because Woodleighs don't come apart but they surely wadded up a bit and penitration suffered..
I have use them a lot in 250 gr. and 300 Gr. in the 338 Win. and they are a absolutly the perfect bullet and kill so well, it still amazes me..
BTW the 300 gr. Woodleigh will traverse and elk lenthwise and most of the time leave a large exit in his front part. the 250 is the best balanced for take any shot on an elk that I know of..They are the equal of a Nosler with a bit less penitraton
in equal weight and more expansion, but both have more than needed in both departments...
Have no fear you are more than prepared for elk hunting with Woodleighs and they kill better than BarnesX, Noslers or Swifts..because they expand and have long ragged arms of lead and coper that resemble a fan blade and it really buzz saws and creates internal damage better than most any bullet...
The Swifts ball up into a smooth ball and pretty mushroom with a puff behind the expanded portion and don't do the damage the Woodleighs do..they are good however on Buffalo for that very reason...
The Nosler is a real penitrator and does not get the cross section that most expanding bullets do. It is in effect a half solid and half soft..It works but not as fast as most bullets, but is very positive and is the bullet by which all others are judged. I also put the BarnesX in this catagory if it works like it is designed to, which is argueable and the GS Custom HV which is a monolithic and seems to allways work...
Thats the way I see it based on my own experiences, and I speak for no one else, nor claim to be the last word on bullet performance, but I ain't far off....
