Hey all,
This is my first post on this great site.I'm going to be doing a lot of coyote hunting this winter and have decided to use the 70 gr. Nosler BT in my .243.I usually use 95 gr BTs for everything, but I'm worried about richocets, hence the 70's.I'm not saving hides, and frankly just want to zap yotes.Is the 70 gr. a good choice, as I'm pretty sure it is?What are your experiences with them?Anybody,feel free to chime in.

Thanks!
SJ
 
Great bullet for accuracy. Not fur friendly, however. But, that's the price you pay for no ricochets. I have shot hundreds of them at groundhogs on flat farm ground and have never seen a ricochet with them. No doubt, it can happen, but I have seen soft nose and, in particular, HP bullets, ricochet under the same conditions.

But, we found we got our best accuracy by keeping the velocities under 3450 fps. I prefer to use SR3031 as it delivers good accuracy even at low temps and gives low extreme spreads. In trying SR4064, SR4350, and several others, we got high extreme spreads in cold temps with this caliber and bullet weight. So, we stick with SR3031 when using the 70 grain bullet in the .243.
 
Thanks for the info.I'm going to use Varget, so I'll try to keep my loads in the 3400 range.As far as not being fur friendly, thats OK by me.Just want to kill 'em.Thanks!
 
That's my favorite bullet for my Tikka .243. Great accuracy with Varget. Great BC. It just flat knocks them down. Like CDR said it is not fur friendly. I think you will be pleased.
 
I disagree with your Muzzle velocity opinions! Why just yesterday I was trying that exact bullet out in my 6MMx284.56.6 grains of H4350 produced 4023 FPS with 1/2" groups at 100,that was my max load,light loads were all above 3,800 FPS with even better accuracy. Nosler 70 gr BT bullets are "Bad to the Bone"
 
I have shot the 70 and 55 from my 6mm, both shoot great but the 55 where tops. The faster I push them...the better they shoot.

I don't know why 3450 fps. seemed to be the point where the accuracy started falling off. But, it happened in each of 4 different .243" Winchesters, a Ruger, Savage, Weatherby Vanguard, and a Mauser. That's why you don't load just on the basis of what the book says ought to be the accuracy load, but on what your rifle likes the best. If your twist is 1 in 12, I would expect to see better accuracy at high velocities. But the twist in all those rifles was supposed to be 1 in 10, and that's what they preferred, for whatever may be the reasons. So, I am happy to let the rifle tell me what it likes to shoot and be satisfied with that. LOL
 
I did not have luck with it in my R700 .243. But the 70 gr. Sierra BlitzKing was amazing.

Might shoot well for you though. I'd certainly try both, and the 75 gr. Vmax as well for good measure.

In my rifle I seat the bullets touching the lands.Also I have a Hart match BBL custom chamber and yes mine has a 10" twist rate. Both Sierra 70 gr Blitz and Noslers have shot clover leaf group in the high 3,900s to 4,000 FPS range. I agree with your style of loading on what your rifle likes. I look at Sierra powder charge recommendations for my rifle and my lightest load surpasses their max loads with no pressure signs.
 
the 70 grain NBT will hammer dogs, out to stupid distances. I shot them last winter and nailed five, at ranges from 125 yards to 300. 4/5 had exit holes which were softball sized. I was pushing them to 3500 fps. Very accurate in my 700 Remmy with Varget (42 grains I think)
 
I shoot 70gr BT's in my 6 Remmy and 65gr V Max in the 6BR.
Very explosive on both accounts and very accurate. The 65gr is more fur friendly believe it or not. It is my preferred cat bullet. Haven't blown up a cat yet with it. The 70 BT is wicked pushed max velocity. I'm running mine at 3600.
 
I run mine at 3650fps. They shoot so well that it looks like one bullet hole with a 3 shot group at a 100 yards. If bone is hit it blows fist size holes or larger in Yotes. I have had a couple of bullet size holes in and out being no bone was hit...but this is not a common sight with the 70 grainers. The bullet hits em like Thor's hammer.
