They worked great in my 1:12 twist 223 Ackley. Wondering how well they do in in a 1:9 twist 223 Rem?

Specifically, how they might perform on our big Northern coyotes, or if they even survive the trip down the bore at 3700 fps plus in the fast twist?

Anyone have any experience with them? It would be nice to hear that they make a teeny little hole going in and don't come out. <img src="/ubbthreads/images/graemlins/cool.gif" alt="" />

No predictions on the penetration potential of a 40 grain bullet, I'd personally use at least a 50 grain if the bullet has a plastic tip to promote blow-up.
Heck, the USDA "gopher choker" killed a male coyote near here a few years ago that weighed 80 pounds. No, it wasn't an immature wolf, nor a "coy-dog."

Hornady shows loads of up to 4600 FPS with their 40 gr. V-Max in a 1 in 8 twist 223 WSSM though they don't say if it reached the target. But being that the 40 gr. NBT has a thicker tapered jacket I imagine it should hold together in a 1 in 9 at 223 velocities.
When you say the 40 gr. NBT's worked well in your 223 AI do you mean accuracy wise or coyote wise?
My 223AI is at GAP right now getting some feeding problems straightened out. When it gets back I have a couple hundred cartridges loaded up with X-terminator and 40 gr. NBT's and plan on getting right in on the coyote population. In the mean time I will make do with a 243 and 25-284 but they are almost like cheating.

at 80 lbs that had to be someone's husky not El Bun...grins

Mark D

Nope. Vermont had a 70+ pounder taken last year. We take them at 50+ down here in VA rather frequently. 80+ ain't impossible.

'Yotes are canines, same as wolves. They are filling the same ecological niche that wolves did/could. Dominance is often a function of physical size and strength. With a relatively high generational turn-over, larger/stronger animals attain dominance, breed more, and thus, the next generation is bigger/stronger. With an ample food supply (as exists east of the Mississippi, 'yotes can, and do, easily get to be wolf size. In essence, that is what they are. Here, at least.

BAY= big a$$ yotes...

Mark D

Yep, and that's a good term for 'em. If I can get a couple of the ones that have been running the local cattle this year, I'll see if I can let ya know what they go. FWIW, they ain't small.

I saw one that a guy near Lake MacIntosh killed that weighed in at 61 pounds and he said it had lost about 9 gallons of blood. I am no expert but it looked 100 % yote. He shot it with a 25.06. It was beat up pretty bad.

9 gallons of blood weighs about 61 pounds.

Accuracy-wise, they shot solid 5/8" groups. Coyote-wise that is still to be determined. Hopefully, I will have a report for you on that in a few weeks. <img src="/ubbthreads/images/graemlins/wink.gif" alt="" />

Ted

Well, 40 gr BTs make it down the 9" twist tube okay. <img src="/ubbthreads/images/graemlins/smile.gif" alt="" />



30 gr W-W 748, CCI 400 primers

Ted

Bummer, is it built off a SUCKS action? Mine is a CRF and had no problems. Just curious. I was worried it would have problems due to the shoulder but so far so good.

AS TO THE ORIGINAL QUESTION...Is the Nosler BT in 40gr a boat tail? I think with the 40grs, you are better off with a flat-base so that there is more contact with the neck since they are short. I am sure others have had good luck with them, but that is just my opinion. I am using Sierra Blitzkings, and they are super accurate.

Dogcatcher,

As you can see from the picture, accuracy is not a problem with the BTs. I was concerned that they might be a bit fragile in a nine inch twist, but they are fine.

Do the Sierras you are using stay inside a coyote? What weight do you use, and what velocity are you getting with them?

Ted

Yukoner, I jus switched to Sierra's this fall. Haven't shot a dog with them yet because I am still in a cast so having to call with my AR.

I have yet to find a bullet that doesn't exit, unless it is a frontal shot and has to travel the length of the coyote.

I was told from a 'yote hunting friend of mine, that the Sierra 40's are the way to go as far as preventing gigantic holes, that is why I switched.

I am getting 3850fps with a 40 out of my 223AI, 22" barrel.

Dogcatcher,
My 223AI is Model Seven based. I'm loading up 40 gr. NBT's in front of a healthy dose of X-Terminator in the 39ish range in a 22" barrel as well. I can't wait to get it back.

Dogcatcher,

Coincidentally, I have just gotten my broken leg out of a cast a few weeks ago, so haven't been able to get out on snowshoes at all. Now we have no snow, as it has all melted in this crazy weather, so will be a bit before I will get serious chance to try the light BTs out.

I would appreciate hearing how the 40 gr Sierras work, and I will get back to you with a report on the BTs............hopefully! <img src="/ubbthreads/images/graemlins/laugh.gif" alt="" />

Ted

FVA,

I have a friend who has been having fits trying to get a Rem 700 in 223 AI to feed. He posts as Rembo on the board here.

Bill Leeper rechambered mine, a 22" Smith & Wesson Howa-actioned sporter, and it feeds like a fat boy at a buffet.

Ted

Yukoner,
I recall Rembo posting something about that. He and I are about the only ones I've heard having problems. I'm not sure why that is but ," Oh, well". My rifle will poke 5 shots into a single big hole so I figure it is will be worth the effort/expense. Glad to hear you don't have any feeding related problems to deal with.

FVA

CRF is the way to go I guess. Mine is built off a Ruger and I have zero problems.

Perhaps but it seems most here are "Sucks" based with nary a complaint.

Back to 40 gr. NBT's. Nosler in their manual states that the NBT's with their thickening at midpoint jacket are designed to reach the target at any velocity.
I think they are it if your gun will shoot them as their I believe highest BC for weight, tapered jacket and solid base give them toughness as well as explosiveness that I'm looking for in a 40 gr bullet .

It shoots them just fine: half inch with 30 gr of W-W 748 and CCI 400 primers. <img src="/ubbthreads/images/graemlins/cool.gif" alt="" />

We'll see how they perform shortly.

Ted

Believe it or not, I know someone who has culled deer with them out of a .22 - .250 at a small airport in a heavily settled area. They do a lot of damage, and if they don't kill the deer immediately, they blow a big hole in them and they leave a substantial blood trail. .22- .250 is faster than a .223 and the bullets hold together long enough to kill those deer.

I had a Rem 700 .223 rechambered to .223AI. It shoots great, but didn't want to feed with the 40gr. Nosler. The point of the bullet hits the sharp shoulder in the chamber and jams. I've played with seating depth and the magazine box. I've got it working pretty well now, but I still don't trust it. Other bullets have fed fine. Neat cartridge. Can't wait to pop a coyote.

I am telling you guys, CRF is the way to go with an Ackley 223. I had nothing done to my Ruger but have the barrel turned back a twist and rechambered.

I have 7 223AI's on Remington receivers.

I'll shoot speed drills with anybody.....................

Ted, I've whacked a bunch of good sized yotes with the 40gr BT @ 4150fps from my 1:14 22-250 (not a 1:9, sorry).

They are an excellent fur bullet (every one of them exited though, with a caliber sized hole (possibly on the solid base remains to exit?). Never even have to break out the needle and floss though....(grin).

For downright pure coyote and wolf thumpin' though, I have yet to see a bullet that can hold it's own with the 50gr VMax. No other bullet has deliverd as many lightening strike kills for me. I will start taking a few pics of the results... as many of them fall and land with their legs under them as if electrocuted!

I found the yotes hit with the 40's (20yds - 350yds) all had a little fight left in them after being hit (albeit only a few seconds worth).

Can't stress enough the "smack" the 50's lay down.... and they are dynamite on woof too.

We run in pretty similar territory you and I, where a monster woof is just as possible as a nice yote, and in my mind 40's just don't have the jam required for long range woof at anything less than perfect angles... which are rare.

I've often compensated for a 40gr BT in the tube sighted for 50gr Vmax's in the belly for follow up/long shots.... works alright but anymore she's just 50's from the get go. Simplicity is key in my simple minded world, and dead dogs bring a smirk to my face.... and a dead woof makes me downright grin!

Good Huntin'

280_ACKLEY

280 Ackley, I will have to give some of those a try, that's for sure. I hear what you are saying about them being better for wolf. They are tough aren't they?

Thanks to all of you for your comments. I will let you know how the 40 BTs work when I finally get out on the land.

Have a Wonderful Christmas, everyone of you, and may the Good Lord bless you and yours abundantly in the New Year!

Ted

So, did you have to do anything to get them to feed? or did they feed with no modifications? What is your bullet of choice?

They required no modifications,though I've seen where a slight spreading of the fore section of the mag box's upper portion,allows them to hang under the feedrails a touch longer to help with some geometries.

I shoot 50gr V-Max expressly in 5(14",12" twists) and 75gr A-Max expressly in 2(8" twist).

I prefer to use the spring clip that pins the follower spring in the forward position,via BDL floorplate. If the follower walks to rear on the non captured version,things can get "weird".

As there is discrepency regarding internal dimensioning,from stock to stock,I'm a fan of using RVT silicone to adhere my mag box in position to the receiver's underside. It's a nice little means of affixing the position,shy of going the IBA welded measure.

I've got/shot 'em all,the 223AI is my pick of the litter..........................

Big stick, did you get a chance to try the 70 gr tripple -X in the 8 twist barrel yet ?

Would like to here some results on that bullet offering......

Nope.............

At least I would like to hear the results!!

Okay, Boys, here's the latest on the 40gr BTs in the 9 inch twist.

Velocity is 3600 fps and the bullets are holding together just fine. They are shooting into 1/2" with max load of 748 and CCI 400 primers. This is at below zero temperatures.

Going to try some H335, next. What are your favourite loads with this powder?

Thanks,
Ted

Up to 27.5 grains of Benchmark powder.

OK, I understand the 50 VMax has more "poop" to it--but how does it do for saving fur? Are you getting exits, and if so, are they large or small?
