Try 46-47g of H or IMR 4064 with a Win primer with the 70's, which will be going 3600 +/- fps.

I killed a lot of yotes with the Sierra 60's with a hot load of Win 760, great bullet.

The 80gr bullets are best out to 600 yards for yote size animals.

I agree. Thats why I stated early in this thread 58g Vmax`s shoot a tight group in MY rifle.I also agree with you need to practice shooting at greater distances to be worth a darn at it. I will be practicing up here as soon as the mud dries a little...a friend at work invited me to go with on a P.Dog shoot..it will be my first and you could say I`m pretty revved up.

What typical style of bullet tends to group easier?

that all depends on the rifle. some will shoot some bullets good some will shoot alot of bullets good. You can never tell what a rifle is going to shoot. That is the fun in reloading the experimentation. HAPPY HUNTING

If you have a 1:10 or less twist and a barrel length 25-26", and with a very warm load you may still have stabilization at 400 yds with those bullets. Bigger bullets, faster twist, slower powder with a min 25" barrel may work better. To me its 200-300yd shooter at best. A 6.5 is a better choice to get that kind of shooting. I have both and use a .243/85 g bullet for shooting 100-200 yds. A 6.5-284 for hunting out to 600 yds with a 140 g bullet.

I have a buddy that i've been hunting with a lot this year. He's using an AR-10 that shoots the 87 V-Max into ~.5 MOA or better. He has a Leupold VX-III with VH reticle and turrets, and has dope for each system on his gun. He also carries an I-Pod Touch with him that has the JBM ballistics program on it that he inputs air density changes into the program every so many hours from a Kestrel. He's shot 5 times from 470-785 yds. now, and killed 4 of them on the 1st shot. The 5th was an error on his part. The 785'er was a through the lung shot and died quickly practically on the spot. A 650-yarder was back in the liver area and took awhile to expire, but we did recover it no addtl. shots needed. To apply shots like this though u need the gizmos and a bullet that'll give u the best chance of expanding at those kind of ranges. IMO, the 87 V-Max is 1 of the best i've seen for all the needed qualities--accuracy, some mass, BC, and polymer-tip which helps with BC and expansion.

The 58's were flying right at about 3,593 fps for me today, and the 70's at 3,445. I may have to go a little further with the 58's, and I think I'll try 4064 with the 70's next. But now that I know I can drive the 70's to this type of speed without any signs of pressure... may just go this route.
