I will be reloading for the following calibers and guns for USPSA.
45ACP
1911
S&W 25-2
Any help you folks can offer will be greatly appreciated.
Go with 230gr (lead or FMJ) and clays(3.7-3.9gr should get you to major with 5" barrel in both guns) and federal #150 primers for 45. N320 is also very good but hard to find and more expensive. Clays is widely available, cheap, and clean, which is important when shooting the wheel gun.
Forget 200gr bullets, much easier to make major with 230gr bullets and to me the recoil feels lighter with the heavy bullet fast powder combo. I also like 14lb recoil springs in my 1911 with this.
Dont try to get a "universal" powder for everything. It may work great in one caliber but it could result in mediocre performance in another. Just be ABSOLUTELY SURE you never bring out more than one powder at a time and either label your powder measure if you don't plan on emptying after each use or dump back into the can.
Tightgroup works well for 9mm
For 40cal I don't recommend loading to major PF if you are new. Clays works VERY well for minor loads. WST is also a good powder. I DO NOT recommend using clays for major in 40 due to clays pressure curve and the fact that a lot of major 40 loads are over published data.
Why shouldn't I reload .40 in Major Power Factor. Is there something I need to be aware of.
I don't think he looked at what you were going to shoot the 40S&W out of. IF, and please keep this in the forefront of your thinking, IF, you are going to shoot the 40S&W ONLY, do I need to repeat that too, ONLY, in your M610 then the ball is wide open for what powders you use.
THE PROBLEM comes into play with the 40S&W when you have an unsupported chamber OR where bullet set back might be a problem......in a semi-auto handgun. Since the M610 revolver has neither, do not fear!
As a caution, if you have a 40S&W semi-auto, since you cannot tell the difference what is on the inside of a round once it is loaded, I would choose something that was safe in both. I have a general rule of thumb, nothing faster than Unique for such situations. If I know that a semi-auto firearm has a fully supported chamber, I will go down to W231/HP-38, but, seriously, nothing faster than that for this caliber. Clays, Titegroup (good for yard fertilizer only), Bullseye, AA#2 and the like are NOT going to find their way into a 40S&W load of mine, never.
Hope this helps, be safe, have fun!
