Cast bullets in a polygonal EAA Gold Team 38 Super work?

Cast bullets in a polygonal EAA Gold Team 38 Super work?
I was always under the impression that cast bullet in polygonal is not good.
I can't imagine a competition shooter purchasing jacketed bullets for practice.
I'm out window shopping right now
TIA

Fit is king. Obduration may be necessary.

Back in the early to mid 90's a buddy and I shot a lot of commercial cast through his Glocks in 9mm, .40 S&W, 10mm and .45ACP without any problems. We also cleaned the guns after every range trip, so no horrendous build up of lead in the barrel.

In my opinion, it isn't the polygonal rifling form that is the problem, it is either fit or lack of maintenance, when using lead projectiles.

Take a wild guess at what was shot in Whitworth rifles with their hex (polygonal) rifling form.

P.S. there is a sticky in the handgun section about cast in Glocks that may answer your questions.

No problem with my Witness Elite Match guns with either cast or powder coated.

I'd try Lee .356-153-2R. I have one and it drops at .358 (clip-on WW). It is designed for .38 Super.

Beautiful pistol!! H&K barrels don't have any trouble with cast boolits. I have 9mm and 40S&W and both shoot straight and don't lead up. But fir is king. I had to play with size to get results.

I have not scrubbed the barrel of my g19 for the last 2000 rounds. I have ran a patch down it to wipe out any powder residue and i clean the outside of the barrel/chamber/feedramp just to see what was going on. Still no leading whatsoever. Sized at 358. Id say if youre careful and read the info that others have gratiously bestowed on us within this forum, youll do just fine with polygonal rifling. Ive only been able to do this because of this site.

I have no trouble with either Glock's hexagonal rifling or HK's polygonal rifling. In fact they were above average accurate. No lead build up after many rounds in either. Glock and HK rifling are not exactly the same as I was told by a barrel manufacturer. Their simple explanation is one is female and the other is male. I've recovered undamaged pistol bullets from both and they certainly do look different from one another.

Thanks all for the help. The pic is not my gun if anyone asks.

Ola, I didn't see a mold for the 356-153-2R on Lee's website for the 38 Super.

That mold was discontinued a number of years ago.

Yes, that is true. If LEE would make them again, I'd buy another one (or two) in 6 cav..

Btw. Is there similar design available else where?

I have a EAA 9mm match and 3 Kahar's , one in 9mm & two in 45 acp no problem with cast & poly rifleing which is 99% of my shooting . from my experience with 380 , 9mm and 38 super in other types of rifleing, from my pistols at least cast bullets sized @.357 work best and are the most accurate even if the barrel has cut, broached, EDM or poly rifleing and slugs @ .355 dia. or slightly larger.

Not to hijack the thread but has any one shot cast boolits out of the Walther PPQ 45 with the polygonal barrel?
