I'm looking in the Lyman Cast Bullet Handbook, it has this.

240 grain lead bullet / 1.500" OAL / IMR 4227 powder Start charge wt. = 12.7 grains / Max charge wt. = 14.2 grains

Start velocity = 664/fps Start pressure = 8300 C.U.P.
Max velocity = 780/fps Max pressure = 12,800 C.U.P.

If you would like a pic of the data I could take a pic and try to upload it. I have done that before but not on this site.

 

Is this for 44 special or the Magnum?? Appreciate it..

 

This data is listed in the Lyman Cast Bullet Handbook under the 44 Smith & Wesson Special.

 

this link is to an old lyman manual with cast bullet loads on line , but data should be about the same

ahh are you aware that almost every powder manufacture has loading data on the web for their powders/ projectiles and is generally the most up to date safe current loadings?

 

Yes, I'm aware but lots of the old loading data has changed over the years do to I expect liability, because of so many old rifle unfit for loading anything very warm. I appreciate your reply..joh

 

Keep in mind that Lyman's 45th ed is the one known as the last of the Pre-lawyer manuals. Starting with the 46th ed, the load data was very anemic for many rounds for "legal" reasons (i.e. so they couldn't be sued). Lyman claims it was due to powder reformulation or some such, but I find it impossible to believe that ALL powder manufacturers reformulated all their powders at the same time.

 

Amen to that

 

I just checked Lyman 44 and it doesn't list a 240 gr lead for 44 spl. It lists a 240 gr jacketed and a 245 gr lead.

240gr jacketed - IMR-4227 15.0gr (813FPS) to 17.5 gr (943FPS)
245gr lead - IMR 4227 - 14.0gr (780FPS) to 18.3gr (1050FPS)
Max OAL is 1.615"

Thanks for the information..john

 

Sorry I’m late to the party. The 45th does not list a 240 gr cast. It does list a 240 gr jacketed, a 232 and 245 cast.

 

I've posted this before, and here it is again. Older reloading manuals that can be downloaded FREE.
