Re: 7mm-08 max range on elk?
The two questions I ask myself when detrming max hunting range for a cartridge/bullet are... 1) at what range does the bullet come to its minimum expanding velocity and.. 2) does it have enough momentum at that range to penetrate completely through the boiler room with a well placed shot. For elk, I look for 40 lb ft of momentum. This is based on what I have observed reported here on LR elk kills and is subjective.
Your max range is dependant on the velocity and terminal performance of the bullet use which is dependant on enviromental contitions such as elevation, temp, etc.
If I was hunting with a 7-08, my first choice of bullet would be a 150 E-Tip (especially for elk) Minimum expanding vel = 1800 fps. My powder would be RL17 which works very well in the 7-08. I would expect an MV of 2900 fps or greater out of a 24" barrel.
Based on that data, if I was hunting elk @ 10,000' elevation I would be comfortable with an 800 yd shot on an elk. The bullet should be able to completely penetrate and hit ribs going in and out and expand. You cant ask for much more than that.
Having said that, elk are tough critters whether you hit them close or far and there is a good chance you'll need a follow up shot. Any guide worth his weight in saw dust will be working a cow/calf call to calm the bull after being shot.
Another bullet choices would be the 160 AB.
Hope that helps,
Just noticed you said DIY... get a mouth reed type cow calf call and practice with it. After making a shot, immediately start a calf in distress type call. This is very effective in calming elk.
