GG, I never kept my 15" long enough to get good loads developed for it. IIRC the Dan Wesson brochures mention the 10" through 15" barrels have a twist rate that differs from the 2.5 through 8 barrels. However, I don't think the actual twist rate is given, it just says optimized for heavier bullets. This usually means a tighter twist.
I wouldn't think you would loose velocity unless your using very light bullets and very slow burning powder. Yet, I don't think there is a powder that couldn't burn completely given the 15" barrel length.
None of my hand loads produced any decent accuracy in the 15 incher I had. One of my loads, a 158 gr semi wad cutter works very well in my 10" barrel. My 124 gr hollow point loads are deadly accurate out of my Marlin 1894 carbine (16" barrel). However, switch the loads between guns and accuracy suffers.
I know from developing loads for target rifle shooting, that matching bullet weight to rifling twist is important. However I'm usually shooting out to 600 yards.
For the Dan Wesson 15" barrel, I would start with heavy bullets and minimum powder then work the powder level up. If you don't get good results, then step down to the next lighter bullet and minimum powder charge, and again work your powder charge up. keep on until you find the magic one. Just keep in mind a tighter rifling twist will produce higher pressure. So if you start getting close to the maximum powder charge for a given bullet weight, start looking for signs of overpressure; sticking cases, flattened primers, etc.

It's the block at the bottom of your post with a cool pic or a favorite phrase. You set it up in your profile IIRC.

Thanks LB. Now that you mention it, I now recall the phrase.

Wayne,
I appreciate you taking the time to thoroughly respond to my questions. I really appreciate it. It looks like I have my homework cut out for me...maybe I'll luck out but I doubt it.
I'll be sure to provide you a range report. It might take some time though.
GG
