A Mixed Day at the Range

I took this week off and my brother had the day off, so we met up at Lower Providence Rod & Gun Club to put some lead downrange. We had mixed luck.

Josh brought his SAR-1, Winchester 1300 Defender 20 gauge, and his girlfriend's Browning Buck Mark Camper. I brought my CZ-52, Ruger New Model Blackhawk, and my carry gun du jour, my Makarov.

We had to start shooting at 50 yards since there were some rifle shooters on the range. (The firing line moves, not targets.) Josh started out with his SAR-1, which worked fine throughout the day. Since I didn't want to stand there waiting, I figured I'd at least function test the CZ-52, since this was the first time I had it out. The 7.62x25 round it fires is pretty flat shooting anyway. The CZ worked well for me for about four magazines full (8 rounds apiece), however, when Josh took a turn it started failing to go into battery. I'm pretty sure that it was magazine-related, since after he cleared the gun and gave it to me, the magzine's floorplate popped off. I was able to get it back on but it came off again under recoil. The same thing happened with the other mag I got with the gun, too. I eventually wound up losing one of the mag floorplates when it went "sproing" off into the air. <Insert string of vile profanities here.>

I managed to run 48 rounds of 1955 vintage Bulgarian 7.62x25 through the CZ-52. All went off without a hitch. I also got about 30 rounds or so of 1954 Yugo 7.62 through it. The very last round required a second hit before it went off. I had not failures to eject.

My overall impression of the CZ remains positive and I think it'll be a nice shooter once I get the magazine situation sorted out. I may get a Hogue Hand-All for the grip, but it wasn't unpleasant to shoot by any means. I did not notice much in the way of trigger slap.

After shooting his AK some, Josh moved to his Winchester Defender, formerly his house gun, and mine at one time. He loaded the mag with four slugs, and the first three times he tried to shoot he got light primer strikes, resulting in failures to fire. NOT good in a defense gun. He also managed to cause a misfeed which he was able to clear without too much difficulty. Once he got all that out of the way the gun worked ok, but he mentioned that he may not hold onto it much longer.

By this time the rifle shooters packed it in and we were able to move up to 50 feet. Time to bring out the hogleg.

I had 30 rounds of Sellier & Bellot 158 grain .357 JSPs and a box of American Eagle 158 grain JSPs for the Blackhawk. Both of these loads have worked well in my EMF/Rossi .357 Mag 1892 Winchester repro. I started with the S&B.

All rounds fired ok but when I went to eject the empties, extraction was sticky and I couldn't fully eject one of the cases. I pulled the cylinder and popped the case out with a cleaning rod, then tried again. Same thing, same chamber. I then tried the Amercian Eagle ammo, in case for some reason the gun just didn't like Czech ammo. Same thing. At that point I decided I didn't want to play with the Ruger any more. .38s worked fine in it when I took it out a couple Saturdays ago, but the higher pressure .357s give the piece indigestion. So now I'm looking at polishing the chambers.

While I was dealing with sticky .357s, Josh was shooting the Browning. It ran fine although he had one or two malfs with the Winchester SV ammo he was using. .22s are picky about what ammo they like, so it may be that this gun needs something else.

Finally, the Makarov. Finally, a gun that works like it's supposed to. I ran 160 rounds of Barnaul ball through the Mak and it Just Worked. Every time I take that gun to the range I am amazed at just what a wonderful gun it is. I now have over 600 rounds through it and the only malfunction was ONE failure of the slide to lock back on an empty mag. It has never failed to feed, fire, or eject. It is the only autoloading pistol I've ever owned that I trust implicitly.

I'm planning to go shooting again tomorrow, but I plan to bring different guns. Except maybe the Makarov.
 
Mixed fortunes eh Dave ... can often be that way.

Was lucky with last few range sessions ... very few probs and my CZ-52 has proved equally likeable ... fortunately (so far!) with no obvious mag probs. It has only digested the S&B Tokarev ammo but likes it!!

Odd re the Blackhawk ........ does sound like some cyl polishing the way to go ... I'm sure you will have considered this but .. fired enough 38 to get a ring problem? Hopefully polishing will remedy the situation.
 
Chris,

I put less than 100 .38s through the Blackhawk and cleaned the chambers afterwards. But I did consider than, so while I was at the range today I cleaned them again, and tried it again with the .357s. No change. :(
 
Hmmmm ........ :( ....... indeed!

Bit more history on this gun then?? Age? Ownership (just you?) ...... number rounds shot? .... percentage approx of .38 vs .357?

I would from here want to try some gauges in the cyls ... unfortunately that's a tad small for a telescope gauge which would suffice .... more needy of a proper cyl gauge.

I wonder tho .. how well or badly do empties fit back in .... ? Is the rogue chamber marked for I/D so you know which one? Are empties I'D'd at all as to where they came out of (which chamber) .... seems like an in depth analysis needed here.
 
Dave,

I bought a .357 Blackhawk last year that had the same problem. Look at the Magnum cases and you will probably find a ring or two that keeps them from extracting. Mine was so bad on two chambers that I had to send it back for a new cylinder.

The gun came back with new cylinder in place but STILL has trouble with some .357's. Looking at the chambers shows them to be rough. It works fine with .38's so maybe I'll just call it a .38 and leave it alone. Rob
 
Before you chuck that B-Hawk, try this:

Clean as normal.

Then, saturate the chambers with Kroil. Let it sit for a few minutes.

Now, chuck an oversized bore brush with tight bristles (bronze only!) into a 3/8ths variable speed drill. Dip the brush in Hoppe's, then brush out each chamber, working the drill in and out. Saturate the brush with Hoppe's for each chamber. Don't forget the cylinder face while you're at it.

Reverse the cylinder, and repeat power brushing from the front of the cylinder. Be careful not to ding up the front of the chambers in any way.

Now, take a slightly worn brush, and hang a good patch over it. Patch out each chamber until it is clean, and repeat.

This should take care of your problem. If not, have your cylinder checked for hard lead plating on the cylinder throats.
 
Chris,

The Blackhawk was made in 1976. I picked it up two weeks ago tonight. It looks like it sat in a drawer since it left the factory. I have the offending chamber IDed.

Powderman,

I was planning to take a patch wrapped around a brush, coat it with a fine lapping compound, and carefully polish the chambers. What do you think compared with your method? The chambers are definitely clean, since the gun has very few rounds through it.

Thanks guys.
 
Powderman's approach is less ''aggressive'' but could well be some careful lapping work would be OK on the offending chamber ... remembering as always ... what is removed cannot be put back!

The ref above to ''lead plating'' is another thing to investigate. I am no gunsmith but I wish we were nearer and i could see the cylinder .. I have various things I would do to investigate the condition of that.

Work with care ....... and i hope you'll get some success.
 
My first thought was that the rvolver had had a steady diet of .38's and built up a ring of fouling that was hanging up the longer .357 cases. But it sounds like you've eliminated that possibility.

I can't see anything wrong with the polishing method you describe. Just take it slow. You can never put any back on after you take it off.
 
Interesting that the Makarov is the one gun that ran fine. If the safety detent spring doesn't go bad on 'em, they'll run forever.
 
Used gun? Only takes ONE hot load to bulge a chamber.

Have you miked the fired cases from that chamber?

I have never found Ruger quality control to be the absolute best, but a "too large" hole in the cylinder could also be a culprit.

Have you tried any Blazer .357? It has a super slick case coating and on the aluminum case, it is probably less likely to form as easily as brass to the chamber.

Just can't resist wondering how this post didn't get MOVED to the Gunsmithing forum.
 
After you lap or otherwise clean the chambers leave them damp and hold ti up to the light. Look at a slight angle and if there is much ridge or bulge you may be able to see it.
