38 S&W load

[chevyiron420]

If you were loading the 38 S&W to about the 650 fps range with 150 grain rn, what powder would you use? Red Dot, Bullseye, other? I have Red Dot and Bullseye, and am currently using Red Dot. My accuracy aint what I had hoped for.

I'd expect Red Dot and or Bullseye to do the trick. What's your load? What's your boolit? What size, lube etc. etc.?

In my circa 1930 Colt Police Positive and Webley & Scott Mark IV I am using Accurate 36-155D cast 1:30 tin/lead, loading as-cast and unsized at .362" diameter and lubricating with LSStuf 45-45-10 and loading 2.5 grains of Bullseye for 790 fps in the Colt and 2.2 grains of Bullseye for 705 fps in the top-break Webley. Both loads shoot "on" to the fixed sights at 10 yards and will stay in golfball sized group at that distance.

The gun is a H&R model 926, vintage 1978, was new condition. The barrel is .361 and throats .362. The boolit is from a NOE mould 363-150RN. This last load was 2.2 grains Red Dot and it made 700 fps. I want to slow it down some more to 650 fps. Its a more modern gun but its still a top break, and I have been warned that they will get loose if the loads arent kept modest. The alloy is air cooled COWW, sized .363 and lubed with Lyman 50/50.
The 12 yard groups went from about 1.5 inch to 5 inch. Some of it is me, a lot isnt. The thing is inconsistent. I handed it off to my son and it shot the same.

Use softer alloy, no harder than 8 BHN, or 50-50 wheelweights and pure lead. Cut your load 10-15% and you will be close to 650 fps. Fiocchi factory loads chronographed 800 fps in my Colt and 770 fps in the Webley. Winchester 146-grain LRN was a full 80 fps less! 720 and 690, respectively.

I hope the alloy isnt causing my problem for two reasons. One is I have almost no pure lead, second is I have cast over a thousand of these boolits. I'll drop the load to two grains and try again. I can also test the loads in my Smith Regulation Police and see how it like them.
