My CASS .45 Colt load is with Trail Boss, at 5.0 grains it fills a large portion of the case and is very consistent and clean burning. For those who have never used Trail Boss this powder is very bulky and light a typical 1 pound container will only hold about 9 oz. of Trail Boss and the powder it self is very odd to look at as it resembles miniature Cheerio's or washers.Is this a solution searching for a problem? I was under the impression that Trail Boss was created for the genre and when I use it for 44 Magnum the loft fills the case nicely and even makes a 240 grain PFM feel like a powder puff in my Marlin.
the cowboy .45 special is a case that is optimized for use with light loads in .45 colt caliber revolvers for cowboy action shooting. Light loads with excessive airspace are a recipe for case splits and erratic function. By using the cowboy .45 special case, with its .45 colt rim and .45 auto length, the problem no longer exists. While many claim that .45 auto load data can be used in this caliber, it is important to realize the limitations of the firearm it is chambered in and only use loads that fall within the pressure range of that firearm. Generally these can be loaded using .45 colt dies and a modified (shortened) crimp die, or .45 auto rim roll crimp die.
You might be mistakenly thinking i'm smart right about now but i cut and pasted that from the starline web site.
Folks have tried the .45CS and the One True Powder. If I remember correctly, 777 worked better with the short case and all. Personally, I don't see the attraction of loading that light but that's just me.Use black powder, as Sam Colt intended, and no worries about big brass!
I'm sure it's for speed. CAS guys are gamers, not realistic real world shooters, just like most other games. I shot IDPA for a while, had to meet a minimum "power factor", but this was easily done in 9x19 unlike IPSC. I loaded it JUST hot enough to make the minimum power factor with a 115 grain bullet.Folks have tried the .45CS and the One True Powder.
