Using jacketed bullet data with cast bullets

[charliek]

How much do I have to modify jacketed bullet load information to use it with cast bullets?

[kungfustyle]

I wouldn't. Get a copy of lymans cast book and stay safe. If you need something specific let me know and I'll look it up for you.

[JSnover]

KFStyle is right. There are too many variables to try a simple conversion.

[Larry Gibson]

As mentioned the Lyman CBH #4 will give you the best info. Otherwise using jacketed data for cast bullets is just a guess, especially with rifle loads.

Thanks all, I have the books which is why I asked the question. I want to use a cast 230 gr bullet in .45 acp. Lyman #47 gives data for a 230 gr. jacketed bullet, but the cast bullet section has only a 225 gr bullet listed. See me as a dunce and a worry wart if you will, but I would like to know what, if any, adaptation is safe. It doesn't seem possible that a 230 gr. cast bullet is unusable.

[JSnover]

It probably is usable but Lyman thought it was impractical to load every available boolit. Compare their loads with some from another manual, you may find exactly what you need.

[Idz]

Jacketed bullets require more pressure to engrave the rifling so the chamber pressure is higher. If you need cast data the Lee book has lots of 230 gr lead bullets. For example 45 acp, 230 gr bullet, Accurate #7 starting loads in the Lee book are 9.9 gr cast, 9.7 gr plated, and 9.9 gr jacketed. You're generally ok using jacketed loadings for cast but not always the other way around. Unless you insist on maximum loads you won't have a problem. Now the big klinker in this is the shape of the bullet is often different for jacketed and cast so setting the OAL gets tricky.

[singleshot]

Start with 225 grain starting loads and work up. You'll be fine.

Lyman's 47 is not the book being mentioned, it is Lyman's Cast Bullet Handbook 4th Edition which is completely dedicated to cast boolit loads....no jacketed!

[bangerjim]

Get the CAST BULLET HANDBOOK from Lyman........NOT #47. Lyman's CBH is ALL cast!!!!!!

Use #47 for a door stop like I do. I just know where it is if I need FMJ info!

I recently purchased the Lyman Cast Bullet Handbook #3 based off recommendations from here and found most data to be outdated AKA for powders that unaccessible to me/commercially available. That being said, I didn't even realize there would be load data so I was quite surprised. I have #4 on my Father's Day wishlist so I hoping for that from Mrs. Claus and the elves. If not, looks like it's time for a present from myself.

[bangerjim]

#4 has modern powders and I love it. Also have #3 for historical (hysterical) info too! You cannot load successfully with modern powders based upon #3 only. I use both. I guess if you use ONLY Unique, as many claim is the ONLY powder to use (hate it), #3 will work. #4 also has MANY more boolit weights and varieties for all cals.

Two other good sources of cast info are the Lee hardbound book and the new Hogdon 2014 annual manual (about $9 in magazine form!) Get them both.

#4 also includes molds not from Lyman. A big help. #4 is the one to get (till #5 comes out)!

[w5pv]

I use the lowest starting load for a jacketed bullet reduce it by 10% and start from there.I have never had any high pressure indications or problems doing this.

You can not read to much from many manuals and compare, but start with Lyman Cast #4. Take no load advice from the web or word of mouth without verifying in at least two manuals.

I would suggest two situations where it can be useful to use jacketed data (caveat is that all my cast experience is with rifles). This is in relation to the Hodgdon 60% reduction rule with H4895 (AR2206H here in Australia). This has proved mighty useful in creating cast bullet loads where only jacketed exist published (for example the Lyman Cast Handbook 3rd or 4th don't have any 35 whelen loads for greater than 200grain cast).
The other situation is using Richard Lee's 1grain reduction method as set out in his Modern Reloading 2nd Ed. This can be used alongside the 60% rule for H4895 or for other powders if he provides the reduction factors for that powder (mostly Hodgden/ADI powders it seems). I am not convinced about his pressure for cast rules but do you his 1grain reduction for velocity rules.

[popper]

I generally use low to mid jacketed data from a GOOD source, same or next heavier boolit. I load COL SHORT of the lands. I don't use really hard alloy or grossly oversized boolits. That should keep you below max PSI. Most of the cast load data I see is 'normal' loading, i.e., what works. Of course, check several sources as loading manuals DO have errors/misprints.

Do any of the following help?

I did just that. I posted a snippet above. Tons of data...
