I'm looking for data for my .38sp loads with Trail Bossfor target shooting. Anyone who will share his "reloading-secrets" with me ?

I use the 158 Lasercast and 3.0 TB for an easy shooting load.

Trail boss works well and I have work up significantly pass the published maximums for better velocities.
Simple rules with TB.
1) Use lead bullets
2) Dont compress the loads.
Good stuff!

I've been loading 3.9 grains of TB under Laser-Cast 158-grain SWCs for a Model 10. It seems to be very pleasant to shoot, but I have yet to chronograph it.

Erich,
I thought I heard something the other day. It was all of your firearms breathing a sigh of relief as they realized you really do know how to shoot light bullets at moderate velocities out of them!

@Erich:
thanks for the information: SD is "seating depht" I suppose, but what is "ES" ?
And wich primers did you use? Is it possible to use small pistol magnums ?
I thougt of building a cartridge with the following components:
a 357 brass, a bullet HBWC (soft lead), 3,0 gr TB and a sp magnum primer.
As one can shoot a SWC from a .38sp. brass, with 3,0gr of TB, firing my cartridge should give the same "sensation" in my cartrigde.
Mounting a SWC in a .38sp brass leaves an "open" space behind the bullet of 0,494", mounting a WC in a 357 brass gives a space of 0,497". The same idd., so if I put 3,0 gr of TB in it, the effect should be the same to ? Or am I wrong?
Total lenght of a HBWC is 0,63" and this goes completely in the brass, length of my SWC is 0,707", and is goes 0,492" in the cartridge.
I just did some rectifications: saw that my language was awfull.

Franske,
I will defer to Erich to answer your questions about SD and ES. Trail Boss is intended to provide bulk thus reducing the air space in the loaded cartridge. I do not load WC bullets, but if it compresses the powder charge when the bullet is seated, I would go to the SWC or other bullet. The magnum primer is not needed for TB and may not be advisable.
3.0 grains of TB with the 158 Lasercast SWC in my 6 inch 686 chronos at M693 and M644 in a 3 inch SP 101.

Skip,
Franske, SD is "standard deviation," a useful statistical device (sort of the average amount of difference that each shot is from the true average). ES is "extreme spread," another one (the difference between the highest and lowest velocities in a string).
Here's a more detailed explanation of SD: http://www.robertniles.com/stats/stdev.shtml

I guess you could but there is really no need to. It doesn't need it for ignition and you may only gain a few feet per second. IMR doesn't list any loads using magnum primers.
I have had great success with trail boss with a 148 wc and 2.8 grns of TB in my colt GC mid range and used that same load in all my snubbie 38 specials. even built a load for my 45acp using 5.0 grns under a 200 grn swc.
