Herco and .44 Magnum.....???
 
I've got a little bit of Herco left in the bottle and wanted to try it in some .44 Magnum loads, but I can't seem to find a legit reloading data for Herco....

I have 200Gr. LFN, and 200Gr. JHP bullets to work with....

Can anyone give me a start and limit load for Herco with these bullets....???

Not looking for nuclear, just mild to reasonable kick loads....thanks....

I am not seeing any data for Herco in a .44 Mag. It does not appear it is an appropriate powder for the cartridge. It it was Alliant would dang sure have data on it.

Alliant has decided that Herco is a shotgun-only powder now and they won't work up loads for it in order to save money. All the powder companies have decided that, since they now have so many powders for sale, that they will group them in a niche and only develop load data for that niche.
Herco is certainly a better powder for .44 Rem Mag than Unique, and Unique is an excellent powder.
In fact, in this case, you can use data for Unique if you know how to work up a load. In most cases with the .44 Mag, Unique's max load will be a starting load for Herco. I would start about 5% below the Unique max and work up.
Some data:
180gn jacketed: 12.2gn Herco start, 13.6gn max
200gn jacketed: 11.7gn Herco start, 13.0gn max
225gn jacketed: 9.9gn Herco start, 11.0gn max
240gn jacketed: 9.5gn Herco start, 10.5gn max
265gn jacketed: 8.6gn Herco start, 9.5gn max
300gn XTP: 8.5gn Herco start, 9.4gn max
300gn lead: 7.2gn Herco start, 8.0gn max

noylj......

I remember several years ago when I first started reloading, I was able to find several loads using Herco in .44 Magnum, .45Lc, and if memory serves me right I recall some data for .357 Magnum. At one time I had a couple of old reloading manuals containing a lot of handgun data for Herco, for whatever reason I gave them away and just use my Speer #13, which contains no Herco data for handguns...... :rolleyes:

Thanks for the information you posted, mucho appreciated......

I'll check my manuals tomorrow. They're pretty old. Might have some more for you to work off of.

i use the Alliant Power Pistol powder in my 44 Spl. and 44 Magnum loads with some really good results.

Herco is one i haven't heard in a long time!

According to Speer #11 you can use Herco, .429" diameter 200 gr "magnum hollow point." 14.8-15.8 grains of powder
Or .429" diameter 225 gr hollow point with 13.2-14.2 grains of powder
Or .429" diameter 240 gr soft point / magnum hollow point / magnum soft point / TMJ with 12.3-13.3 grains of powder

According to Lyman 45th you can use Herco, 225 grain half-jacket, 11.0-14.5 grains of powder
Or 240 gr jacketed with 10.0-13.5 grains of powder
Or 180 grain cast with 11.0-15.0 grains of powder
Or 205 grain cast with gas check with 11.0-15.0 grains of powder
Or 215 grain cast with gas check with 11.0-15.0 grains of powder
Or 250 grain cast with gas check with 10.0-13.0 grains of powder
Or 232 grain cast with 10.0-14.0 grains of powder (doesn't say anything about a gas check)

Nothing in my Hornady third edition. Did you want expected velocities as well? What about 44 special loads?

Thank you very much JWSchramm....

If you have any .44Spl. loads listed for 200Gr. LRN bullets, that would be a big help as well.....

Much appreciated.....

Notta problem boss. Glad I could help. Lets see...

Speer - 200 gr magnum hollow point - 6.5-7.5 grains powder

That's all it lists for 200gr bullets, unfortunately. And Lyman and Hornady don't have anything listed at all for 44 Special using Herco powder. As long as you keep it on the light end of the magnum loads, you'll be ok. Now,if you had 240 gr semi wad cutters, or 225 gr hollow points, or 240 gr soft points/magnum hollow points/magnum soft points, there would be more possibilities coming from the Speer manual.
