I think I have a problem with diameter

[cwlongshot]

Wow nueces5... answers all over the board!!

I also shoot a lot of cast out of Glocks, factory and AM barrels.

Since PCing I have been seeing great results. Most of my cast comp bullets are about 14 BHN and powder coat. I shot many thousands last season and the barrels are clean as a whistle! I have been using CLAYS powder for about 1050 ish fps. (Mine are 40, I don't do 9) T tell the honest truth, I have more issues with AM barrels with cast!!
Don't listen to the hype. Be smart keep the barrel clean, shoot PC properly coated and DONT WORRY! 10's of thousands of rounds over a couple years are how I know.

I agree, adj your OAL. hardness "requirements" change with velocity. I load softer (10-12) with some cast and still PC with no issues. BUT I don't push velocity, I strive for accuracy, IF that comes with velocity, I adjust as needed. For me, function and Accuracy are most important. Steel and paper don't complain much at how fast the bullet impacts them. GAME use changes things but I get the impression your talking target here.

Good luck,

I think you mean the boolits needs to seat deeper so casemouth coincide with the start of the taper...

Whatever. It was late last night. Anyway the COL looks too long......

Glock recommends not using lead bullets in their weapons.

Glock also recommends to not use reloaded ammo as well. I have never had a problem with either.

[Tom W.]

Almost all manufactures say not to use handloaded or reloaded ammo..... maybe because Bubba once loaded a .454 to the top with BE and made a compressed load....

I would say you may need to seat the bullet deeper and reduce powder charge and that crimp looks to still be flared at the mouth. Take some calipers and measure just below the mouth and then measure the mouth and see if it still has flare. I usually fail the plubk test with cast because the bullet is engaging the rifling. And yours looks like it may. But without it and the barrel in hand i cant say certainly.

last night I made a couple of dummies, decreasing the oal, and now turns perfect in the bedroom.
Disarmed and measured, and has 3555
I'll wait for the lathesmith expander

Just so some understand, Nueces5 is from Argentina, & English is "not" his first language.

The reason I mention that, is in case someone comes along & does not understand his use of the term, "bedroom", or other terms that do not translate "exactly".

In translation, "chamber", comes thru as "bedroom".

"Armed" round, means, "loaded" round, and "disarmed" round, means "unloaded" round.

I just thought I would mention that, so some do not give the man a "ration of ****", for the use of terms that are not quite understood by all due to translation difficulties.

{ No , it has not happened yet, but I am trying to, "head things off at the pass.". There are some who are..."That guy"... So, try not to be, "That guy". }

I think it is pretty cool that someone from a country that does not share the same language, or does not fluently speak English, is taking the time to come here to CB.GL. forum for advice.
{Yes, I know that there are & have been others, but I still think it is pretty cool. How may others here that have English as a first language, have been going on to other countries forums that do not use English as a common language & ask for advice in "their language"? Yep... Pretty cool in my book...}

Anyway.. Just thought I would mention it...

Thanks JB! Let's add that I have a fever tonight, I can put anything and I will not notice

I don't know current stats, but seem to recall CB had members from 26 countries as members.

I think that is great!

Is that am after market bbl? In stock glock bbls I run 0.357" bullets, lubed, HT or PC coated, always good accuracy & never a keyhole. In after market bbls, the bore us often a bit tighter so I can get by with 0.356".

[cwlongshot]

Yes and the chamber will be tighter as well.

I have 4-5 aftermarket barrels. Reliability with cast is poor at best. With Jacketed they are nearly 100%!
