I have not tried it but read of a lot of success by others with 68 grain and up bullets. Like mentioned, the kernels are long which makes it bulky, and more difficult to fit a max charge into a 223 case.Anyone try imr4064?

So far the consensus is that 8208 works out of an AR with 77gr. What’s the difference loading for an AR vs bolt gun? Why does it shoot better in an AR vs bolt gun?
This is the same proof prefit you’ve been using throughout your posts in this thread?88's right at 2700 and 85.5's about 50fps faster
I'll have to check my notes later for COAL to the lands. Currently I am seating them to 2.490" as feeding can become questionable if I get much closer to 2.5" in a couple of my older AI mags.This is the same proof prefit you’ve been using throughout your posts in this thread?
What are you COALs for each of the bullets?
You seem to be getting pretty quick speeds considering you have a pretty short free bore.
Has this rifle ”officially” moved from being a trainer to match rifle?
Im about to build a 223Al trainer which I’m somewhat hoping will be my main rifle for comps inside of 700yards.
N140 or Varget, you dont need anything else unless you want a ball powder for a thrower. I throw Varget ok and trickle up.Thank you
And you seat the 85's to function in an AR Mag.?AA2520 24.3 gr 85gr burger 2567 fps 1:7 LC brass 7 1/2 rem AR15
Anyone tried running the Hornady 75 A max at AR Mag length.
Too hot or ok? Finger nail doesn't catch on the spot where the firing pin hits.
Cci 450 with a Tikka. Here is .5gr less powder.What primer and action? Looks like you are getting flow back up into the firing pin hole. The edges look nice and round so I wouldn't worry about pressure.
I have heard sometimes it looks a little worse than it is with Tikkas but I am not sure. Need to go shoot something loaded close to factory power with those primers and see how it looks.Yeah looks like some primer flow but not a big deal.
Yes.no biggie with 2520 .did some testing with vv140 an 150 . Could hear the crunch when seating bullet to mag . even put a dent in the bullet.anyway I won't likely be using vv140 or vv150 .vv540 should be here in a few daysAnd you seat the 85's to function in an AR Mag.?
Does anyone know if Hornady sells the 73 gr FTX projectiles for loading? I can't seem to find any but can find their loaded ammo available.
AR or Bolt?I have some 80 smk loaded with 24.5g of varget and 77 smk with 24g of varget to try. Pretty classic service rifle loads so I'm hoping for good results. Anyone measure 80 smk to the lands in their wylde chamber? I'm right at 2.500" which seems longer than most people. Not really a big deal, more room for powder just curious.
Wylde chambered bolt gun.AR or Bolt?
Sounds about right. Maybe a touch long for the standard Wylde chamber.Wylde chambered bolt gun.
I could contact the Smith and probably get the reamer print. I don't see why it wouldn't be a true wylde. Doesn't really matter either way, I was just curious why mine is longer than most seem to report.Sounds about right. Maybe a touch long for the standard Wylde chamber.
I had mine chambered to hit the lands with an 80g ELDM at 2.510" with I want to say .080" freebore. So not your standard Wylde chamber, but close enough anyway.
yes ,yes i do . and some powders don't like it . i do however have a Bob's sled ,works the best in the UPR . a bit less convenient in the AR"sAnd you seat the 85's to function in an AR Mag.?
Interesting I thought the wylde freebore was .025. I have an .080 freebore and seat the 80 SMK out to 2.52 at touch.I could contact the Smith and probably get the reamer print.

My freebore is .062 and in touching at 2.500" so that would make sense.Interesting I thought the wylde freebore was .025. I have an .080 freebore and seat the 80 SMK out to 2.52 at touch.
How fast are you looking to fly?What is the best powder for good ES/SD and temp stability that will push the 75-85 class bullets and meter well from the Dillion Powder thrower.
I know this is a tall order, but I want to set a 750 up just for 223 practice/local match loads.
8202 is impossible to find.
N140?
Benchmark?
for me TAC was a wast of time and material got better with the 68gr bulletsI've heard TAC is a great powder for metering/accuracy/velocity. But I also hear mixed reviews on the temp stable part.
Benchmark wouldn't be a bad choice. It meters well and is temp insensitive. Should get decent accuracy/velocity also.
Not sure on N140, but ya cant go wromg with Vihtavouri powders either.
I might suggest N540. Been shooting it in my 223 with 75s and getting great velocity/accuracy. I don't throw charges, but I couldn't see it not working decent from a thrower. It's a double base powder but the kernels aren't really big.
not all 85 are the same ,barnes are on the shorter sideAnd you seat the 85's to function in an AR Mag.?
i'd suggest testing to see lf you really need to crimpFor 223/556 I want to crimp for an autoloader. My bullets do have a crimp groove or cannelure. Lee Factory Crimp Die or Redding Micro-adjustable Taper Crimp die?
no not for me. my ar's like 2520,15.5 , RL15,CFE 223,So far the consensus is that 8208 works out of an AR with 77gr. What’s the difference loading for an AR vs bolt gun? Why does it shoot better in an AR vs bolt gun?
you should buy 8 lb of n140I have never been successful at working up a great load for my gas gun but went to work on it today and finally found a load that had great numbers and shot small.

I am sitting on a few jugs but thanks!you should buy 8 lb of n140

N140?
Benchmark?
25 shots that would be a go for meHere is my latest load. I shot two 25 round strings. I know the 223 is pretty finicky on getting low SD/ES. Are these numbers about right or should I be getting better results?
Starline 223 brass
Sierra 80g smk
24.5g varget
Remington 7 1/2 primer
In a 223?For those looking to compare N140 vs Varget I finally tested Yesterday.
Loading 43.7G on a 80.5 Berger gave me 2729 FPS vs 2821 on Varget.
Loading 24.92 on the same 80.5s gave me 2891 vs 2989 for Varget.
28" barrel loading long.
YMMV
I have all but given up with tack. Will be trying it with 68&69 24" 1:8I got the Dillion 750 setup/dialed in for bulk loading precision .223.
Going to try this load out tonight and shoot for ES/SD/Groups:
Trim to 1.755
COAL 2.415
Berger 80.5 Fullbore
24.4gr TAC
CCI 450
Random LC/Federal Brass
Was able to get casefeeder and bullet feeder dialed in. Runs really well except every 25 rounds or so a primer doesnt get seated and it drops powder through flash hole. It may be a timing issue but not a deal breaker yet.
