I usually use h110 with my 357 loads, local supplier has been out of it for some time now. So I bought some 2400 instead, dont really have any data for it except what i find on alliants web site. They list a load of 14.8 grains with a speer gdhp for a velocity of 1265. Anyone use 2400 with the xtp's? Or have any data for the 2400 other than what I have stated already. Thanks for any input you may wish to give.

That exact load works VERY well in all my rugers. I ran 2400 from 13.5 to well past 15, 14.8 gave me the best SD and ES numbers, as well as the most accuracy.

Just be aware that it is right at the top of the chart, start a bit lower and work up to it. Doubt you'll have trouble, but better safe than sorry.

thank you ben, that's really what i was wondering. If that was a starting load or a max load. once again thanks

I run 14 grains of 2400 and regular primers. It is a good stout load without running on the ragged edge.

What gun will you be shooting these loads in ?
My Hornady data from 1994 lists;
S&W 27
case trim to: 1.280
Fed 200 primer
158gr XTP
start, 11.5gr 2400
Max, 13.5gr 2400

Works for me too, under 158 grain Speer JHP bullets.:)

Although 15.0gr 2400 will closely match the factory velocities of a Speer 158gr GDHP round I also found like Ben Shepherd said, 14.8gr 2400 will give you better numbers and accuracy. If you're looking for a good load that's the one you should try.

This is the load I use too. Out of my S&W M66 4" using Remington bulk 158gr JSP's it chronographs right at factory ballistics at 1,243 fps.

With 2400 14grs and just about any 158 gr jacketed and 13.5 with just about any lead bullet works for me.

You might want to try Lil' Gun also.

[appalachainamerican]

thank you all, the guns I'll be running these through are two colt pythons, a ruger sp101, and a ruger gp100. Lil gun was my second choice, but local supplier has none of that either. I really like the results I get with h110, hope 2400 works as well.

Is anybody using small pistol magnum primers with 2400? Any info on that?

[rcmodel]

2400 does not require Magnum primers for good ignition.

Some tests I have seen indicate more pressure variation (extreme spread) between shots when using Magnum primers.

Accuracy is usually not as good either.

thanks the only reason I ask is because I had some magnum primers and didnt want to have to go buy any more primers I would be using these in my 66-4 smith for conceal carry.

[rcmodel]

Some load data you see does call for Magnum primers with 2400.

The Lyman #49 shows mag primers with every powder tested for instance.

It won't hurt anything if you want to use them.

Lyman shows 158 XTP loads using 2400 & mag primer as:
11.3 Starting.
14.9 MAX.

The suggestions in earlier posts to use 14.0 grains is spot on.

2400 usually doesn't burn at all well with starting loads.

Thanks for all the info I appreciate it.
