Jacketed vs lead and barrel wear

Post by lanjo on Sun Jan 08, 2017 11:19 pm

Hi All,

I have a newbie question.  Do jacketed pistol bullets wear out a barrel faster than lead? I have a match accurate K38 and 1911 both worked up by pistol smiths. I use lead bullets for competitions and they are quite accurate. I shoot indoor in the winter months, and the indoor range only allows jacketed bullets. I got caught shooting lead and got a warning recently. I need to shoot jacketed bullets or I could get banned from the club. Will the shooting of jacketed bullets from my bulls eye guns wear out the barrels and reduce there life span? I shoot both the 38 special and 45 at ~ 750-800 fps.

Best,

lanjo

Probably easier on barrels. Not that the bullet is any easier but less worry about leading and excessive cleaning. Excessive cleaning is hard on barrels. If you are really worried you could switch to a platted bullet. The only reason they want you to switch is some lawyer said they have to worry about lead levels. Platted bullets will fulfill the coating requirement. They won't be as accurate (observed by me) but indoors should be fine. Whatever you do don't let them know that primers are a greater contributor to the perceived problem. They may make you find "safe" primers. What do they do about the .22 shooters?

The 22 shooters can use lead.  Maybe they think the coated bullets put less lead into the air.

When you say probably easier on barrels, bo you mean lead bullets or jacketed?

I just re-barreled a .38 spl 1911 with sleeved barrel. Assume Douglas 1:10 twist blank. Pistol was built in 91. 148 gr hbwc only bullet fired through barrel. It was the most worn out barrel I have ever seen! I was very surprised because I have my own high mileage .38 that still shoots phenomenally well. So it's really hard to say.

Jacketed are probably easier.

Ask if they'll accept coated "hi-tek coating" lead bullets.  Leading and vaporized lead is almost nil.

Is it possible the barrel was overcleaned?

How often do you clean. I clean about once every 500 rounds? A little more rounds,  if I am shooting a cleaner powder.

Just my own experience with 4 Kart barrels, so this is not to be interpreted as a given. 2 of those 4 have been on my first wad gun. The other 2 are on my hardball gun & my second wad gun.

My first Kart was gone in less than 30,000 rounds.  I had put a lot of jacketed and very hard cast that had been water quenched through it.  It went from a 2" barrel to a 5" barrel, @ 50 yards, from my Ransom rest. 

The current Kart barrel, on the same slide & frame, has had over 40,000 rounds of 99% cast range scrap (BN of 8-9) and maybe a 1000-1500 of Nostler & Zero 185 JHP, and still has no problems holding 2".  Originally this barrel would produce a 1 1/2"-1 3/4" group fairly consistently, so it may be wearing or my loading technique was off for that load/test session.

The Kart on my hardball gun has seen about 2500 jacketed, >95% of those were full hardball and just last year I worked up a load with Zero 185 JHP, so there's a hundred or so of those.  It's also seen several thousand long line rounds of cast H&G 68 with 4.2 of WST.

I'm willing to bet there's more than a few BE smiths on here that have either been military armorers or know a few that can give you a much larger picture than just one person's experience, but this was mine. FWIW

Great thread, and excellent topic. All my shooting life I have always heard that lead, being softer than jacketed material, was much easier on barrel life. How could I be so dumb as to not think of or consider cleaning the bore. Oops, my bad. Not only have I shot lead only, or mainly, in all of my .45 autos, I have been handloading a very light target load. I'm totally dumbfounded to have not considered scrubbing the bore. I'll bet that if this query is posted up on other forums, most peeps will claim that lead being softer, will damage the bore less. No more scrubbing the hell out of my barrel. To make matters worse for me, if at all possible, I can't shoot all that good anyway, so I am sure that I would not notice the difference.

What about JB Bore Cleaning Compound?  It states it will 'not injure the finest bore'.  But I have heard it contains very fine abrasives and works like a lapping compound, which does not sound like a good thing when trying to clean a bore.

There's a thread going on or was going on the last couple of days in which the OP stated that he used it & it had some black particles from hois bore scrub with this product
