Jeff, why not set up some wet newsprint at long distance and see how the bullet does there? My thinking, based on side-by-side comparisons I've done with other 35s at closer distances is that the Sierra GK is a bit hard, probably fine for 200 yard shots when hitting substantive targets (with the 358). At longer distances, I think you'll want a bullet with a softer core which can help get things opened up some. Shooting deer in the rain forests of Oregon with solids seems a bit "iffy" to me, 35 caliber or not.
