500 S&W HandiRifle handloading ?

[rock-steady]

Howdy. I have gathered everthing to load my own 500SW's. I have H110, H322, and H335 powders on hand. I was wondering if anyone had any advice before i start. My first bullets are the 325gr Speer UnicoJHP. Any input will help. thanks.

Have you found published data for H-322 or H-335?  Those are rifle powders. I thought some of those powders should work good.  I am planning on handloading for my 500 as well.  I am looking for lower pressure loads, midrange, but I dont really want to go to the fast burning pistol powders.

Please post your results.

You need a copy of this magazine article.

I am shooting 10 grains of Unique with 420 gr lead gc bullets.  They are very comfortable to shoot and very accurate.

I bought that magazine, I dont recall any use of "rifle" powders.  I think IMR/H 4198 would work great in this cartridge.  Sort of a modernized 50-70 load.

The only rifle powder listed in the Taffin article is 5744.

Is H110 a rifle powder?

[xhare]

H110 is primarily used in cartridges such as 357 or 44 magnum, and of course other magnum pistol loads.  I suppose that there is also data for the 410 shotgun.

I was unaware of 5744, I will have to check it out and see where its burn rate falls.  Thanks for the correction.

Here's Accurate's data on the 5744.

I am working on some loads with H110. So far they have shot as well as the other powders I have used such as H4227 and Lil gun. H110 seems to be equal to Lil gun according to the ballistics from hodgdon. H110 is a lot cleaner though. I also use these powders in my Redhawk .45LC. I have been using Hornady 350gr copper JHP in the 500 and sierra 350 jsp.

I'd like to try the Trail Boss.  It seems interesting in many calibers.

I emailed Hodgdon asking for rifle data hoping they might have a suggestion for one of their Extreme rifle powders, they don't.

There is no data for this cartridge in rifles.  The data for the pistols
is all there is.  You will just get slightly higher velocity with the
rifle but the pressures will be the same.

Thanks for the input quickdtoo. I used 43gr of H110 and the Speer 325gr unicore JHP. I fired 12 rounds to set the sights and get the feel of the 500Handi. Recoil was similar to a 12 gauge with field loads. 3 shot groups with open sights ran about 3 inches at 100yds. I put an old scope on to check accuracy, the scope elevation adjustment is messed up, but I fired two shots that touched, just hit about 10 inches low. I have a new 2.5x scope on the way and some Sierra 400gr SP's. This is fun.
