Thought I would share:

155 grain Precision Moly Bullet, 5.5 grains of Red Dot, COL =1.13

velocity on a 90 degree day == 1137FPS, PF==176(mass x velocity/1000)

shot from a 5 inch 1911 Bar Sto Barrel.

no signs of excess pressure.

I backed them off to 5.2 grains.

Velocity on a 90 degree day == 1102 FPS, PF==170 (mass x velocity/1000)

Why Red Dot: it fills the case, and it was in stock. As it turns out, it shoots nicely as well.

Congrats! I wish I was more daring with trying out different loads. But sadly, I like to stick with what works and not ever change. I am just boring like that. :supergrin:

Yeah, RD is very bulky. I bought a pound to see if it would be a good substitute for Bullseye since BE is hard to see at the bottom of a 38 case. I haven't gotton around to trying it yet. I like 3.5-4.0 BE with a 180 cast bullet in 40SW and I figure the same dose of RD would work just as well and fill the case more.

Nothing wrong w/ that... I'm the same way. :). I've stuck w/ 231 forever because I was comfortable with it, and was fairly accurate in my auto disk. I have a can of WST I intend to try(after reading Fred's posts for so long) for 9mm and .45, and will eventually probably get a can of WSF to try for 40.

I am glad I am not the only one, LOL. I just have always been taught that if it aint broke, don't fix it. My loads are plenty accurate and make holes in paper just fine.

Let me know how those other powders work out for you! :wavey:

How many grains for a 180gr bullet?

I have used a lot of RD in 45colt, a bit in 45acp. It does bulk nice & at least w/ lead bullets, accuracy is very good. I think you are running a bit hard @ 5.5gr though, backing down a bit is prudent.

I added the 5.2 load data results
