7.62x39 deer loads?

[flashman2]

OK right the Hornady Superformance Match ammo...

https://www.hornady.com/ammunition/rifle/223-rem-75-gr-bthp-superformance-match#!/

75gr BTHP @ 2930 fps from a 24" barrel. I should try these in my Hog Hunter which has a 20" barrel so probably 100 fps less (~2830 fps MV), or in my Mini 14 which has a 18-1/2" barrel so probably 150 fps less (~2780 fps MV). Except it's a match bullet and may not be suitable for game?

It's basically a copy of the 77gr SMK. It's a BTHP and pretty devastating. Too devastating for deer at close range IMHO. I've shot coyote with them and the wounds are impressive. There's plenty of pics out there showing their performance on deer too.

I used to also load the 75 A Max, it's an incredible bullet for the .223. Think it's been replaced by the ELD X now though. I had them going 3100 fps out of a 24" barrel which gives the below ballistics. They're waaaay over mag length though, OAL was 2.503"

Hornady 75gr Superformance Match advertised ballistics are inflated. This article states their ammo chronographed at 2778 fps from a 24" barrel vs. 2930 fps claimed.

What were we saying about .223 downrange energy being higher than the 7.62x39?

As I said, I found their performance underrated. I chronoed them when I was shooting them for the brass and had them closer to 3000 fps. Even at the 2778, it still beats factory x39 past 200 yards.

See above... my 3100 fps 75 grain load beats your x39 after 300 yards

That 75gr BTHP 0.4 b.c. sure makes a difference downrange. Now if I can find a higher ballistic coefficient .303 bullet and increase muzzle speed a bit more...

.485 for the ELD X! Impressive stuff for sure. But you need an AI length mag which limits their usefulness in most rifles, and preferably a looooong throat.

Maybe someone could talk Berger into making a VLD .311? Out of a #1 that would be cool.

I'd be real tempted to try a 150 gr out of your #1 in 7.62x39... pushed over max as for the 125 gr that'd be a pretty sweet load. I would guess 2300 + fps would be achievable with CFE BLK

I forgot to mention that .308 bullets are quite useable in 7.62x39 rifles. Here's the ballistics for the Sierra .308 155gr HPBT Palma MatchKing. No problem getting 2400 fps MV with 150gr .308 bullets from my Ruger No.1. Now it has more energy than your .223 at 800 yards.

Right, the ELD X! I didn't consider that one. I'll be back...

 

[Slamfire]

The Hornady 155gr ELD Match has a b.c. of 0.46 which is about the same as the Sierra 155gr HPBT Palma MatchKing. Another choice for a high b.c bullet useable in the 7.62x39.

Nice, that's true .30-30 velocity with a bullet that has 2x the BC as a 150 RN. And with much less powder. So you have better than .30-30 performance in a micro action cartridge.

Mind you, that opens the can of worms as to what one could do with a #1 in .30-30 and a Spitzer bullet... hmmmm.

 

[Slamfire]

The designer of the Ruger No.1 rifle purportedly never did succeed in blowing apart the action with extreme pressure loads during destructive testing. The barrel sheared off first. So it isn't the action itself that's the weak link. Appears to be the threaded connection of the barrel to the action.

Regardless it still isn't recommended to exceed published maximum loads listed for the 7.62x39.

 

[Slamfire]

Right, that's a whole new bag of worms. Unknown if .30-30 brass can withstand the pressure. 7.62x39 brass is rather thick-walled in comparison.

 

[flashman2]

Well heck, even pushed 200 fps faster you're at better than 6.5x55 energy albeit with a worse BC.

 

[Slamfire]

I have 2 other Ruger No.1 rifles, a .45-70 and 9.3x74R, and both can digest maximum loads without any apparent signs of excessive pressure. All 3 of my No.1 rifles (only!) handle +P loads no problem. Calculations - based on assumptions to be verified - indicate at 50,000 psi chamber pressure in my 7.62x39, chamber and barrel stresses are below the yield strength of the steel assuming it's made of AISI 4140 which it likely is.

Sellier&Bellot 7.62 x 39mm SP looks great to 100m and falls like a stone at 200m .

I'm debating do I bring my 8mm for a back up. I am pretty sure my little CZ has the power and my longest shot will likely be under 100m with the rare area up maybe 200m. I just love the lighter weight and dogging thru the woods should be easier because of it.

123gr SP @ 2437 fps (743 m/s) is a bit faster than Winchester factory loads. Deer slayer.

BC for x39 bullets is kinda funny

I think you could push a x39 cartridge in a no.1 untill you start seeing brass close to failure. It's a pretty low pressure round due to the rifles originally chambered. Stick it in a No 1 and go nuts

 

[Slamfire]

SAAMI maximum pressure limit for the 7.62x39 is comparatively low at 45,000 psi. 7mm-08 is 61,000 psi.

Sellier&Bellot 7.62 x 39mm SP looks great to 100m and falls like a stone at 200m .

Unless I was only shooting over a power line cut in ON I'd just take the 527 and be done with it. In 25 years of hunting and a couple hundred ruminants bagged I could count on one hand the number shot over 100 yards or that took more than one round. When I was a young dumb teenager I hunted moose with a .416 Rigby... the older I get the more I like light rifles in light recoiling chamberings. If I didn't already have a 7mm-08 and Mini 30 I'd hunt with a 527 in x39 in a heartbeat. Zero 3.5" high at 100 and you'll be on out to 200. Limit yourself to broadside shots only after 150 and it'll do the job.

Another bullet for use in the Ruger No.1 7.62x39, the Nosler 30 caliber 170gr Partition at 2065 fps MV. Could probably squeeze a little more speed out of it.

 

[flashman2]

Pretty cool. Something nifty about bullets seated out long, dunno what it is.

The only issue I can see is they'll be below the listed expansion velocity after 75 yds, but inside that they should be a hammer on bear or deer.
