.38 special bullets loaded into a 9mm cartridge...

I'm just gonna assume that it is a no no... Perhaps due to the .38 projectile being longer... And therefore creating more pressure when fired...?

Please don't beat me

Interesting read on this

The only reason it is a no-no is the length and shape of the bullet won't feed in a semi-auto.

38 Spcl bullets are .357" and 9mm jacketed bullets are .355". The .002" difference means nothing.

Hmmmm okay! Thank you so much!

I have been also thinking about trying some .357 bullets to reload in my 9mm.
Thanks for the link to the data .
I like that the article says that the recoil seems a bit softer. I wonder how accuracy will be.

Got to go reload.

No problem. Choose a bullet that will feed. Start low and work up, same as any other load. Find what works the best.

I've done it several times, berry's 158gr round nose work perfectly, they are just a bit long. I've also tried my own 158gr cast and some jacketed 158gr TC but those didn't feed very well in my glock so i use them in my ruger blackhawk convertable.

38 spl bullets are .358 diameter in lead and will be hard to fit into a 9mm case and less likely to chamber. Yes the .002 larger will have a effect. What will be yours to figure out. Yes I have tried it with mixed results. It is your gun and fingers so it is up to you.
Weight and depth of seating increase pressure.

Cam-Pro 125 grain .357 bullets work well in 9mm in my experience.

Would like to experiment. Just worried about the longer bullet engaging into the rifling...

This is my concern...

When using lead bullets it is very common to use .357 diameter projectiles in the 9mm. I and thousands of others have loaded probably millions of .357" sized bullets in the 9mm so no, it won't make a difference. The trick is to properly bell the case mouth before trying to seat the bullet.

The bullet should not "engage" into the rifling at all. No handgun bullets should be loaded so long as to engage the rifling. I suspect you mean the bullet "bearing surface". And I am not sure how a longer bearing surface would have any effect on the load?
