anybody chronograph any of the igman 6.5x55 139 gr SP's?

i have some that i am going to pull the bullets on because when i shot it the primers were blowing.

edited to update:

i have pulled the bullets from this ammo, charge weight seems pretty consistent at 39 grains of whatever powder they are using. it is short grained "extruded" in appearance.

what i have notice though is the the force required with my impact puller to pull the bullets varied by quite a bit, some took barely any force, while others required multiple hard hits before the bullet would come out.

your "blown" primers, were they just falling out of the pockets or were they pierced?

Igman glues the bullets in place (I am told)...

Check the flash hole in the primer pockets....does it look minuscule to you?

In my experience, the firing of Igman (especially in colder temperatures) had me believe they were somewhat underloaded, probably due to the smaller than normal flash holes. I would have cases blackened all the way back to the rim, because they were not sealing the chamber correctly.

I have about 200 rounds of factory igman left, but I don't use it due to the above. I however reload the 300+ empty cases I saved. Needs a bit of prep work but after it works fine.

hmmmmm, good to know, I have some of this:(
 
Mig25, are you shooting an ag42 (m42B)? It just could be that you have an extended fireing pin. When the first ones came into the country, there was a little kit that came with them with spare fireing pins, extractors, springs and plungers because of this problem. bearhunter

first three shots seemed fine, then on the fourth bolt lift was heavy and on the fifth and sixth bolt lift was heavy and the primers were falling out. i am using a swedish '96. this ammo does seem to be very accurate though.

i pulled almost the rest of the box when i broke my impact puller (too much 8x63 from marstar i think). so i still have 2 rounds left.

the bullets are boattails btw.
 
yeah, sounds right. I never had heavy bolt tho :runaway:

If the primer is falling out, it is either because there is not enough pressure to re-seat it after ignition, or worse, too much headspace? :confused:

are the cases sooty at all? (other than around the neck, I mean down the shoulder all the way to the head?)

can you measure a fired case and check and post the length?

fired cases are clean. i will measure a case when i get the chance.

i only had the one box of softpoint ammo, but i have 250 rounds of FMJ with the same headstamp that i hope i have no problems with.

never had any problems with this rifle shooting privi partizan (the nny headstamp stuff that used to come in the century boxes) or with winchester or remington.

I had exactly the same experience last weekend with my swede.

The IGman was as black as pitch...

The Norma was fine...

I thought it was just me.

The first I heard of this problem was on milsurpshooter.com. It seems alot of people have the "sooty-cases" problem.

When I have the time I am going to cut one of those igmans in half and post a pic of the flash hole....they are friggen miniscule, and not quite in the centre :rolleyes:
 
igman ammo

I just returned from the range, shooting a Tikka T3 and a AG42b both in 6.5X55. I tried the igman 139 gr soft point ammo in both and was pleasantly surprised. The Tikka shot a 1.25 group and the AG42ba shot a 2.50 group (original open sights). I did note the primers were flat but no other signs of pressure. I then continued shooting with my reloads so I cant comment on barrel fowling.

I'm considering buying some Ingman for my M38, is the issue of the primer coming out common?
Also, can anything be done about the flash hole issue?

After I shot the ammo, I used my Lyman flash hole reamer (from the case mouth) with the spent primer still seated of course, then I decapped and proceeded to clean, resize etc.
It's easy and works very well.
 
Ive never had a problem with igmans 7.62x54r in my 91/30 although the firing pin depth is adjustable on the mosin so i have it hitting just enough to set the round off no problems with blackening on the case anywhere
