PC,

I noticed the difference in the newer run with the silver primers.

no complaints with the older version having the brass colored primers.

i'm sure the newer ones will be fine, i'm just too critical...

at any rate, my new carry ammo will be federal trophy bonded JSP 180 gr.
it's even a little hotter.

o.k., what I ended up doing was to use my kinetic puller to move the bullets where they needed to be (and it seemed like they slid out way too easy, just a few light taps) and then gave them a light taper crimp.

all's well.

maybe it's just me, but this shouldn't be necessary on premium ammunition.

thanks for your interest shadow. 

yikes!   

I did mean 1.250" and 1.253".

I just weighed them, the recessed cartridge and the in spec one are the same at 265 gr.
so at least I know they do have a powder charge.

I think you already did a pull doc on this newer sig round, but thanks for the kind offer.

by the way, was there any kind of crimp on that round?

hello shadow,

I found 2 that I consider out of spec.

one at 1.194", the other at 1.229".
the rest ran around 1.50" to 1.53".

the people at sig want me to send pictures (which i'm not set up to do).
I don't understand why they won't let me send the actual bullets back to them, i'm sure UPS or FED-EX would do it.
I wasn't able to actually talk to anyone in the ammunition manufacturing dept.

anyway, I think i'll pull the bullets out to spec length and taper crimp them lightly and call it good.

in the meanwhile, I hope federal will start making HST 10mm ammo...

just received an order of sig sauer 10mm 180 gr. V-crown ammo.

not happy.

one the rounds I examined was as short as 1.194", the hornady book lists the c.o.l. as 1.260" max.
i'm betting this is close to a compressed load. the difference in length here just jumps out at you.

there is no evidence of any sort of a crimp on this batch (120 rnds.)
also the skiving is absent at the nose of the bullet. this newer batch has the silver primer.

by contrast, my previous ammo from them had a distinct taper crimp, noticeable skiving on the bullet and a brass colored primer (not that this makes any difference, just pointing it out).

I have contacted the factory about this and hope to get an answer.

don't want to bash sig sauer but to me there is a big drop in quality since i first started using their fmj and h/p ammo.

any thoughts, comments?

thanks.

that's true, it was just a starting load. it chronographed at 1015 fps.

I have since ordered starline brass and will up the powder charge.

the sig brass is in the scrap bucket.

my first 10mm was a glock20 gen4.

I bought a bunch of sig 180 gr. fmj with the intent of using the fired brass for reloading.
there were no signs of the dreaded glock "smile" on the brass after the initial firing.

my reloaded ammo I used was 9.6 gr. of blue dot with X-treme 180 gr. heavy plated concave base flat points.
I did see the smiles after the first reloading. the cases were not bulged but there was a line on the brass where it was not supported in the chamber.
to me this indicates a weakness in the case and makes it suspect for further reloading.

this particular load is not in the "hot" category. makes me wonder about sig brass.

I haven't shot the glock since I fell in love with my new D/W razorback...

never had any experience with them.

I also have a ruger SR1911 (sadly neglected now, 10mm rules!) and this has never happened with it.

come to think of it, I did have a failure to go into battery. I dropped the mag and racked the slide to clear the chamber and continued to shoot.

could this have somehow kinked the spring?

I really like the razorback and plan to keep it stock. great shooting pistol.

oh yeah, also have a glock20 gen4. it languishes in the safe too...

no, sorry i'm not set up for posting pictures.

the best way I can describe it is a 1 inch section that kind of jinks off to the side a little bit and then the spring returns to normal orientation.

it is a stock spring and as mentioned, very stout.

i'm at a loss to see how it could deform at such a low round count.

it didn't seem to affect the performance of the pistol. however I wonder if I should replace it before the next outing.

hello all,

new member here and proud to be a part of this very informative site.

I bought a D/W razorback and am still in the breaking in phase (250 rnds. so far, no malfs).

this is the fourth time I've taken it down for a detailed cleaning and noticed something amiss.

the recoil spring has a distinct kink about an inch and a half past the end of the end of the recoil guide rod.

I've been very careful about reassembly and use a J.B. JOHNS 1911 bushing tool due to very stout recoil spring and tight bushing.

has anyone here run across this, should I contact D/W customer service?

thanks for any advice.
