Pardini HP .32 acp stovepipe

[dmw6455]

Just received my Pardini HP .32 acp. Went to the range with 3 loads. Hornady 60 grain xtp factory load, Special Hornady 60 grain xtp factory load and my own load (Hornady 60 grain xtp with 1.8 v310 per Vladimir). Was testing for groups, so was shooting off a sandbag. All 3 were giving one stove pipe practically for every 5 shots. This was a brand new pistol that I shot right out of the box without any cleaning. The only thing I did was add a Ultradot Match dot scope. Normally, if it was my own load I would bump up a tenth of grain and see what happened, but was had this even with the factory loads. Any ideas anyone?

Look up "Pardini HP ammo" talk there is a lot of info that will help you out.
What size groups are you getting.

[dmw6455]

I did not shoot enough rounds to determine group size. Got side tracked with the stovepipe issue. Seems like others resolved the problem by changing the mag spring to the .22 spring. I will call Pardini tomorrow and ask that question.

[Jodykid]

Let me know what you come up with. I pick up my HP32 on Thursday.

Talked to Alix this morning from Pardini and the fix for the stove piping is just as someone else said. You need to order the .22 magazine springs and remove the .32 spring and put in the .22 springs. It seems that due to the light loads of the .32 acp the bolt does not return fast enough in relation to the push of the .32 magazine springs. I asked him about getting a lighter recoil spring instead, but he said this seems to solve the problem. Will let you know how they work after I receive them and test.

[Trooperjake]

The mag spring or recoil spring is not the problem,
the problem is the lips of the mag are too wide and let the bullet out too soon.
Search my name on this forum for a photo of how to correct the problem. I no longer have the photo.
I shot a match yesterday and not one problem with feeding. I have 5 mags.
It surprises me Pardini has not picked up on this.

[conradin]

I have the SP with the 32 conversion. Never have any problem when shooting 32.

[Trooperjake]

Use a 9/32" drill as a test Rod.
Tap carefully where the arrows point.
The original posting is titled, "Pardini 32 HP ammo talk"
I cannot take credit for it, this was a big problem and someone else cured it,
I only took a photo to help others.

[dmw6455]

Thanks. I will give that a try.

[Murph]

tune the mags as described, and use 22 mag springs......and it'll be your favorite gun.
That's all I did and mine runs perfect with any ammo and all loads.

[cgroppi]

What's interesting is not everyone has this problem. My 32 ACP has worked perfectly without any messing about from the day I got it. Never had to mess with magazine lips, springs or anything.

I did have a few stovepipes with my lead bullet load when I tried decreasing the charge from 2.0gr to 1.9gr of titegroup, but the problem went away when I went back to the hotter load.

dmw6455,
When you get the bugs ironed out, you will love this pistol. Follow Trooperjake's suggestions; they helped me with same issue. For 60gr Hornady JHPs, the current hot load is: 2.30 grains Tigegroup, seat depth 0.925, fed primer, crimp 0.332. This load gives excellent accuracy at 50 yards. I am currently using Federal Ni brass that I bought from one of the online used brass suppliers. I've summarized the 32 ACP load data from various sources; ONLY USE THESE DATA AS A GUIDE IN CONJUNCTION WITH ALL RELOADING PRECAUTIONS. Good luck, dipnet

Thanks for the great load info. I will definitely try the titegroup.

[Dipnet]

I just received a notification this morning that Titegroup was available at: http://www.butchsreloading.com/shop/rel ... -1lbs.html

Can anyone tell me how you take the magazine apart to change springs. I must be dense as I have tried all the normal methods one uses to take apart magazines, but can't do it.

[Trooperjake]

There is a single pin in the plastic base, be careful when pulling it apart after drifting the pin.

[dmw6455]

Update: Changed the magazine springs to the .22 springs. It works. Only 1 stovepipe in 80 shots. May also do the other fix recommended. Still not comfortable reporting results on my loads as I am getting larger groups than others are reporting for both the Hornady 60 with 1.8 of V310 and 2.3 of Titegroup. Right now the V310 load is better. Waiting on getting an X-small powder bar from Dillon and do a few other tweaks to make sure the loads are more accurate. Been testing off 4 3" blocks and 2 sandbags, so not as accurate a method as a Ransom rest.

[pistol champ]

tune the mags as described, and use 22 mag springs......and it'll be your favorite gun.
That's all I did and mine runs perfect with any ammo and all loads.

I also did the springs and mag change and now have no problems at all thousands of rounds without a stovepipe. I could not get through 3 rounds without getting a stove pipe when I first got mine.

If it isn't already too late, I think you would be better off getting the Unitek measure except it is a lot more expensive. It was recommended somewhere that the plastic model is a better choice. This is what I bought and am satisfied with it. It is very easy to get to an individual load if you kept records of how it was adjusted the last time as it is quite repeatable.

I am presently using 1.5 grains of tightgroup with the 60 grain lead bullet and have no problems. I cut two coils off my stock magazine spring, bent the edges in and have a 22 recoil spring. I don't know if it would be a good idea to shoot 60 grain jacketed bullets at commercial speeds with the 22 recoil spring though.

I believe that I need to do the mod to my mag lips. Just to be sure I understand, is the 9/32 drill supposed to stay in the lips until the end as it is pulled out?
