Happy Thanksgiving!

I finally got a chance to confirm the velocities and accuracy of the above powders driving a RimRock 180 Hard cast LSWC w/ gas check .358"

I keep hearing that H110 is the "better" powder for 180 gr.
But I kept getting better results with 2400. I thought I got the rounds mixed up when I first tested this. So I went out and did it again, and yep, 2400 beats H110 in every combo I tried.
I wanted H110 to do better because I have a lot of it. And only 1lb of 2400.

In my 4" 686 with 2400 loaded slightly above published data and H110 at max I got the following on a rest at 25 yards.

H110 w/ CCI 550
13.5 gn
Avg 1083 fps (ES 61)
4 Inch groups
Cratered primers

2400 w/std Rem #1-1/2
More than 12.6 gn
Avg 1230 (ES 27 )
2 inch groups
no preasure signs

I have had similar results with 140 to 158 gr with 2400 beating H110 but not by this much.

Maybe its just my revolver?

Is anyone else getting this type of results from 2400 vs H110.
my 642 Airweight gets fed HS 6 and titegroup so I havnt tried it with these powders.
BTW , I seem to enjoy shooting the 180gr pills over all others. Its becoming my favorite load to shoot. Feels like a true magnum load without the sting. The penatration is extensive and I noticed the recoil of 2400 was much more pleasant too.
