Shooters World Heavy Pistol (Lovex D037.2)

I just bought 3 lbs of the subject powder. I normally shoot 2400 in reduced .30-06 loads. 2400 has proven to be a great powder for reduced cast bullet loads in various calibers. Unfortunately, finding 2400 is close to impossible these days.

I've recently read up on the SW Heavy Pistol and see that it is very close to Accurate No. 9. My guess is it is the same stuff, just made in CZ. The Powder Valley site and the SW site both say that the powder is similar in burn rate to No. 9 and in application to No. 9 and 2400.

Has anyone tried this yet in reduced cast bullet rifle loads? I'm looking for a starting charge. If I cannot find one, I'll interpolate using .44 mag loads/vel/pressures for the 3 powders to come up with a starting load.

Happy to share anything I learn here as I go down the load development road.

regards,
Rob

I use 16 grains of WC820, Enforcer, AA No.9 for 7.62x54R in a Model 27 Finn, 314299 sized .314, WLR primers, 3-4" 200yds, battle sights also good to 300M on Pigs, longest I have used this load

Thanks. Here is a short table with some non-scientific comparisons give on the right. This load data is from the OEM manuals or Lyman's book and for 240 gr bullets in a .44mag.

PowderMin LoadMin VelMax LoadMax VelMax PresMin Vel FPS/grMax Vel FPS/grPSI/gr
No. 918.1125520.2142634,45269.3470.591705.54
240018.291522.2116535,30050.2752.481590.09
Hvy Pistol15.5108018.8140635,92069.6874.791910.64

The relationships on the right are purely to give a rudimentary feel for the differences between the 3 powders. The No. 9 and HP do seem to be much closer to each other than the either is to 2400. 2400 produces higher pressures for lower velocities which also lines up with the faster burn rate. Although the HP seems to make more pressure for a lower velocity. But then again, that data was for a jacketed 240 gr bullet as there was no lead bullet data. That could be the cause for the higher pressure at a lower velocity. I'm no ballistician.

Have you shot those loads over a chronograph? If so, what kind of muzzle velocity do you get?

Although a bit shorter than a .30-06, I would expect the pressure and velocity out of your round to be pretty close to what I'd get with the 06 round, assuming all other things equal.

Comparing the 2400 data above for .44mag to my data for .30-06, which is 17gr of 2400 under a 207 gr NOE 314210 bullet cast 20:1 with NRA lube, I see muzzle velocity in the 1430 fps range. That's pretty much the sweet spot for achieving good accuracy all the way out to 500 yds.

So, if I assume everything is linear (probably a mistake) and the increase in velocity I see in my 06 over the .44mag with 2400 is similar to what I can expect from Hvy Pistol, then that gives me a starting point of 13.8 gr of HP.

WARNING: THIS NOTHING MORE THAN A DISCUSSION. IT IS NOT TO BE TAKEN AS FACT NOR USED TO CREATE YOUR OWN LOADS.

I figured I should put that warning in here or some nudnick will take these numbers and run.

regards,
Rob

somewhere I have the Chrono results, I'll look tomorrow to see if I still have them
I started using WC820 when it first become available here in OH, do not remember the year, using consistent group size, not scientific at all, WC 820 aka H108, No.9, Enforcer aka 4100, all seem to give the same results in my Finn, I have only used HER 2400, in my 44Mag, 40 years ago, never bought any after that, surplus was 6.00/pound at the time
I am almost out of WC820, so I went to Aliant 300MP, a little slower than W296, have been using 12.8 in my 32-40, breech seated 215gr bullet, 1-25, with very good results, WLRM primer are best so far, have burned 10 pounds of it

We have a couple guys shooting .32-40 in various single shots, Hepburn, High Wall and 44-1/2, rifles. 2400 has worked very well. That caliber is not supposed to do well at long distance according to one of the shooters and the Schuetzen guys. But he's getting amazing groups at 500 yds with his Shuttleworth 44-1/2.

Acurate No. 9 is supposedly the powder to use in .25-20 single shot. Same guy with the .32-40 was not getting consistent groups. He'd get a keeper and then he'd get a flyer or the next group would be a shotgun pattern. He tried 2400 and the groups shrunk and stayed that way.

for breech seating a 32-40, 12.8-13.5 grains of Aliant 300MP, with WLRM primers, 1-14 twist, NOE 32-323 or the Paul Jones copy at 100yds

I normally do not like to post pic's but, one was shot in 2008 and one this year same rifle, No.1 Ruger, Douglas Barrel. SST, 36X Leupold with FCH and Dot, both bench rest no wind flags, 5 shot groups witnessed, the one from 2008 is a Jerry Barnett bullet, 210 gr

Back to the powder, could not find the chrono loads from the M/N, only 32-20 and 357max, different powder etc.
my friend has a Radar chrono and I know we did the M/N.
I did find a 200yd target, it is WC820, my friend does equal with Enforcer/4100

Between some .44 Mag load data and some chrono data from Chuck for AA No. 9, I think I can start a load testing process once this cold spike moves one. Temps in the teens tends to dissuade a day outdoors on the bench.

My intent is to use a ladder process, 5 rounds each of various loads, probably at half grain intervals shot over a chrono at a bullseye set at 100 yds. Everything else will remain the same. Using my NOE 314210 bullet cast at 20:1, Fed Gold Match primers and Fed cases. Rifle will be my 03 Springfield with a 20X Unertl.

I also am going to plot the velocity vs grains of powder just to see what kind of curve it generates. I've been doing that with min/max loads out of the Lyman CBH just to see if it can be used as an indicator for other loads. Granted, 2 points is not what you'd call a data-pool and the straight line it makes is probably not truly representative of how the powder charge affects the velocity. That said, I plotted 2400 first and the slope of the lines were very similar. I then plotted AA No. 9 and the slopes were almost identical. I wish I could figure out how to put this stuff in Excel to produce the plots. But I cannot find a chart that will do what I want it to do. So, I'm stuck with graph paper, a ruler and a pencil. Should change my alias to Fred Flintstone.
