New to Reloading: Question on Bullets

[JSH1]

Looking to load 32 S&W Long and 32 H&R Magnum.

I finally found some powder last week. The powder is H110 which isn't ideal but I do have some recipes for it in my manual. However, the bullet specified is a Speer JHP / 100 grains / 0.312" Dia. I can't find that bullet. However, I can find a Hornady XTP JHP / 100 grains / 0.312 Dia. From my research it seems I shouldn't have a problem substituting bullets as long as the bullet is seated to the same depth so keep the case volume is the same. Is that correct?

Yes, as internal bullet seating depth is what is cricial to case volume/pressure.

Speaking to bullet preference/case volume only, Zero is my favored brand for price/performance.

Is there something I'm missing in this equation?

You're good.

Put the crimp in the cannelure- thats your seating depth

Generally bullets of the same type ( jacketed/ cast/plated) can use the same respective data for bullets of the same weight exactly as your research lead you to. Really abnormal examples of bullet shape can lead to issues, but "standard" bullets like you mentioned have similar bore contact surfaces along their respective weight lines.

Most of the "problems" seem to occur when substituting jackted data for lead, lead data for jacketed, etc. When you mix in plated bullets, and plated bonded bullets ( like the GDHP) is where pressures start to get a little funky. Unusual material combinations usually lead to odd bullet profiles ( giving more or less bullet to bore fit along the shank of the bullet) which can cause some pretty drastic pressure changes.

Like said above, you're good... The reason why load data gives a range of charge weights is the slight differences in bullets but in this case both bullets are so similar you will probably see little to no difference in performance.

IMO H110 is totally unsuitable for .32 Long (Yes, my Speer manual shows a H110 load in .32 Long), and marginally suitable for .32 Mag.

But the answer to your question is yes.

Like I said, H110 is less than ideal but it is the first pistol powder I've seen since I bought my press almost a year ago. I've seen some powder online but I refuse to pay $30 for a pound of powder and then double that with the Hazmat fee.

Thanks everyone for the information of bullets. That confirms what I've read:

• Case volume is what is important
• You can't mix and match load data for jacketed vs lead bullets

Pretty much. Good luck finding pistol powder. If we were close, I'd fix you up.
