Nope i just neck sized 50 rounds, primed them and fired them. all went off on first hit. then i screwed my depriming tool way down so i dont resize any thing and i deprimed the same 50. primed them and all went off. then i did the same again but i added powder and lead. i shot 15 this morning and i had 8 i had to strike twice. It makes know since to me at all!!!

CCI primers?

twocan · « **Reply #32 on:** January 19, 2009, 01:57:46 PM »

yes 2 differant ones and also winchester and one more i cant think of off hand. These are all large rifle primers.

twocan · « **Reply #33 on:** January 19, 2009, 04:53:58 PM »

OK i took a file to the hammer. I had .043 of firing pin now i got .065 maybe just maybe this will do it. I will know by noon tomorrow.

ok i tried to shoot my new brass full length sized rounds this morning. even know i had more firing pin sticking out it still would not fire every time. then i found 7 once fired small primer brass so i neck sized them loaded them and no missfires. i loaded them again and no missfires, and again

21 all together with no missfires. then i neck sized and loaded up 5 once fired lage primer brass. no missfires

So now im off to load 20 more large primer brass. ill let you know how it goes this eving. Also i was asked by a old man if i have tried large pistol primer. would this be safe? he said there softer???

twocan · « **Reply #35 on:** January 20, 2009, 10:57:03 AM »

i loaded 20 more with large rifle primers and i had 3 misfires. ill just wait on my sping new spring now!

OBXPilgrim · « **Reply #36 on:** January 21, 2009, 02:26:20 PM »

So, twocan...when you fire off those primers in the empty brass, is the primer sticking out the back of the case afterwards? Everyone I've ever done this on backs the primer out - it can push the shoulder of your brass back after doing it a few times. I think that's why you've done it a couple times & then get misfires.

I've checked lots of fired brass in my barrel & if it's the least bit short, I've opened the neck up some using different pistol caliber neck expander dies (.38 spl). Just like making a false shoulder, size it back down with your 7.62x39 die until it just drops, then lock the ring!!

Also, you can seat the primers too deep in the brass, just seat them in firm until they are flush.

I've also switched to cast lead - one heck of an efficent cartridge. I can actually seat the slug out to touch (or just short) of the rifling. My 311407 cast slug (180gr GC) can be loaded up to 1880 fps - faster, but the accuracy went south.

So far with these steps, I've been 100% first hammer hit reliable.

twocan · « **Reply #37 on:** January 21, 2009, 03:29:11 PM »

I dont recall primers pushing out any when i was doing that but not 100% and yes on the primers being flush. I made sure of that and you lost me alittle on the shoulder stuff. my new spring should be here by the weekend.

Well I will chime in here as I like the little Russian. I had one of the 7.62x39 barrels and shot several rounds from different manufactures through it. The head space was all wrong and misfires were rampant. It wasn't accurate and A shame too as I know that it can do a lot better. If Remington offered it up in a correct chamber I would buy another. A real shame about the last batch offerings...many had hopes of a fun barrel, and a fun one it would be if done correctly. I would like to see a .308 bore with a good chamber. But even still if people intend to use import ammo with .311 ammo I would'nt fault them for the popular decision. It's just a fun round, Auto, Semi, or even Single shot...

thats what i'm talk'n bout!!!
remington might be able to produce one that will do the job.......
would be nice if more people would agree to this.
and would like to have one or three

i'd like to see a 7.62X39 with the bore sized .308....that would be a nice set-up,considering all the .308 bullets available

I shoot .308 bullets anyway in all my .310 bored x39's and have done tests and found no measurable decrease in accuracy vs .310 diameter bullets. To that end I simply use the much superior selection of .308" bullets for my needs

I POSTED THIS PREVIOUSLY ELSEWHERE

It's been pretty hotly contested as to how much diffrence there is between loading 7.62x39 using .308 bullets vs .310-.311 so here it is. I tested this and here are the results.

The rifle is a CZ527 carbine topped with a 3x9x40 redfield accutrac scope. The bore measures .300 land to land and .3105 in the grooves

The ammo was loaded with 150 gr Sierre soft points 10 rds of .308 and 10 rds of the same bullet sized .311. Cases were Remington CCI 400 , The powder was 23.5grs of Re-7 with a COL of 2.310

It was about 65 degrees today with a light varible breeze of 15 mph

Shot string 1
.308 bullets

1851
1826
1852
1827
1846
***************
Shot string 2
.311 bullets

1935
1904
1937
1912
1925

Shot string 3
.311 bullets

1953
1888 !?
1915

1925
***************

shot string 4
.308 bullets

1852
1855
1869
1844
1873

All velocities were taken at 25 feet.

As you can see there is very little diffrence in group size. About the only real measurable diffrence in using the .308 dia bullets is that they are somewhat slower in the FPS department.

Of course your mileage may vary.

I'm totally amazed that a manufacturer would produce a barrel in 7.62x39 and not anticipate that people would want to use cheap milsurp ammo. The round itself was designed for military use. I would have thought H&R might have tested a few barrels and not released any if the problem couldn't be remedied. That said, there are other choices for this very versatile round to be shot in.

coyotejoe · « **Reply #43 on:** January 24, 2009, 07:52:09 AM »

This is one I personally just can't see. At best the 7.62x39 is "almost" a 30/30. The cheap ammo may be an attraction but it is generally inaccurate and not good for much but making noise and from the posts here it seems it's not always good even for that. The 30/30 is accurate with factory or handloads. Factory 30/30 ammo is the least expensive centerfire ammo available and is a well proved deer slayer. You can buy 30/30 anyplace that sells ammo at all. Why would anyone want an "almost" 30/30 when they can get the real thing?

gendoc · « **Reply #44 on:** January 24, 2009, 08:15:19 AM »

well, when you got 10,000 rounds and 5 other shooters that use the 39, it would just be handi to have one. and you say there inaccurate? i got a cz 39 that will out shoot a 30/30 in a heart beat.
i guess its just what you want and what you can do with it.

Care to back that claim up

I challenge anybody with any kind of 30-30 shooting factory ammunition to beat this 9 shot group I fired with "inaccurate" $2.99 a box Monarch 123grn fmj's and that's 300 METERS not yards

Don't make the mistake of associating inaccurate platforms with the ability of the cartridge. 7.62x39 can be an astoundingly accurate chambering when you don't have a bunch of hamfists who haven't a clue how to make a quality firearm in the 21'st century cutting your chamber. In fact the most accurate cartridges in the world are based on x39

Think PPC cartrideges and you have the 39s offspring, I haven't shot my CZ past 100 yards yet but it shoots clover leafs if I point it right. Heck my Russian SKS shoots as well as my .30-30 at a hundred, It'll do two inches if ya try hard.

Rustyinfla · « **Reply #48 on:** January 24, 2009, 01:44:46 PM »

Why not just buy a .30-30?

gendoc · « **Reply #49 on:** January 25, 2009, 04:54:38 AM »

cause i got this thing for a 39!!!
its called unlimited ammo and 5 other shooters.

read the previous threads......

Last spring I picked up a Handi with a 7.62x39 barrel. I bought some Wolf 122grn hollowpoint ammo and about 60% needed to be struck twice, but it was very accurate for hitting soup cans at 150 yards. I tried Winchester & Remington ammo that I got from the Walmart and I had to strike much of that twice too. Then I picked up 300 rounds of Lapua 123grn FMJ match grade ammo and to date I haven't had to strike any of that twice. I haven't reloaded any of the Lapau brass, but am planning to do so for some spring shooting. I'm hoping that I have the same results, which would be very nice. But even shooting with the Wolf ammo is fun, and it's cheap. The Wolf, Remington & Winchester all do fine in my Mini Thirty, so that's where I shoot it.

I sent my 7.62x39 off friday to be threaded and cut down to 16.5 for my suppressor.

I plan on reloading 200 grain 308 rounds for a nice sub sonic round.

Funny. So did I....but the suppressor is still on order. I've had good luck with the .303 180 grain Remington CoreLockt Round nose (moly coated) over 6gr of Red Dot. Primers holes bored to 3.5mm and magnum primers. Keeps 'em about 1030fps out of the original length barrel. Of course, that will change once cut to 16.25". My bore slugged out to .311 so I have to use the larger bullets. I've never had any luck with milsurp or Wolf ammo in this one...but I bought it for subsonic handloads anyway.

gendoc · « **Reply #53 on:** February 05, 2009, 03:16:51 PM »

well i was, but was told of problems h&r/nef had with them.
i have found a like new one. and as soon as i can try my titanium nitrate firing pin out
that i fabricated, and modified the hammer,transfer bar and trig assemblies on a nw frame. it might open up a new outlook but first i'm going to try it on another frame to see if i encounter the same failures as mentioned.
i should know by tomorrow afternoon.

gendoc · « **Reply #54 on:** February 07, 2009, 03:19:11 AM »

its a done deal!!!
the nv receiver did have misfires with russian commercial ammo

BUT!!!!!!

the modified nw receiver with removed metal from hammer at contact with transfer bar, double coil spring
and titanium fire pin with extended tip.

will handle anything you feed it from wolf, monark, sue and even handloads.
fired over 250 rounds and not one fireless strike.

hard primer issues are a thing of the past!!!!!!!!!

and the accuracy is excellent. i'm pleased

Making the poll is not difficult. I'll do it if you guys want me too.

Might even do one for a 7x57

go ahead, and make OUR day!!!!!
since the problem is solved, maybe remington will do the magic!!
i'm now working on a second fire pin/trigger spring/hammer mod for my brother.
it does'nt have to be percise, as is the same with the original design.
computerized machineing equipment can make anything!!
