Barrel question?

Post by Texas1911 » Thu Mar 21, 2019 3:09 pm

A little background.

I have a SFx. I've slugged the bore and it's .356, this means I need to shoot a .357 cast bullet. Anything less causes leading. However getting .357 bullets to chamber is pretty hard. I'd like to have the barrel throated but need to know if it's salt bath nitrated aka melonite or just a carbon steel barrel?

I've been sizing all my 9mm bullets to .358 for years, and have yet to find a factory barrel that wouldn't chamber them. How are they not chambering?

But to answer your question, it should be a Duracoat/Cerecoat type finish. The wear on my barrel's finish is far too extensive to be melonited.

How long are you loading? May need to go a little shorter.

If your loading a bullet that has a long shank like the 135 or 147 grain pills, that can cause chambering problems if the OAL jams the bullet into the lands. Nooshoot has it right.

I have had problems with oal not chambering In ppx and sfx. Do a drop test drop a bullet in you uninstalled barrel round should chunk in the chamber and be easily removed with you finger nails if seating bullet deeper doesn't help you might just have to buy a resizer Lee has one under 20 bucks

per my gunsmith, the barrel is hardened and will require a carbide tool to cut a leade; he did not have one.

Honestly I don’t think you have to worry about leading if you clean your bore after each range session. I guess it could become a problem if you didn’t though.

I don't know if this will help you but, I had problems with cast bullets shooting in my TP9SA, keyholing and leading, so in desperation I gave 124 grain poly coated bullets a try and that solved my problems. accuracy is pretty good considering plain cast were all over the target frame.
