Alright, so I went powder hunting and the local gander mountain has a pile of red dot and green dot powder. I don't have listings in my manual for either powder, and the only thing I could find online (alliant is pretty biased toward speer) is a load for a 200 grain speer LSWC. Could I use this data for a LRNFP of the same weight. They're the same bullets from Missouri I've been loading over the Trailboss. Looking for something with a little more whump to it. There was a listing on handloads.com but I don't trust anything unpublished.

I doubt the loads Alliant shows are at maximum pressure, they would not want customers complaining about leading from that soft swaged bullet. I think you are OK to work up from 10% below.

Comparing the data speer sent me with the data on Alliant and it looks like they are showing the max charge. Still a good idea to start 10% under? I assume you mean 10% under max by the way.

Red Dot does fine with hard cast slugs in every pistol I load for - but these are just moderate target loads.
no experience at all with Green Dot.

Here's Alliant's real load data; I downloaded it before they new and improved the web site and ruined it:

Red Dot is wonderful in .45 Colt. My favorite .45 load for my Ruger Bisley/Blackhawk is a 230 grain cast bullet with enough Red Dot for about 19500 PSI. I shoot a lot hotter stuff in it too, but I keep coming back to this load. (not giving the load data because it's well over SAAMI specs)

Green Dot works good too. I just haven't used it as much.

I use green dot for 44spl and have recently dialed in a new lightened 44mag load for target. Recoil is really light and accuracy seems to be good out of my 7.5" super blackhawks with 210gr SJHP's or 210gr silvertips. Velocities are decent, but don't expect more than 1200fps.

Lee's manual has a good bit of info on green dot. I started using it because I'd heard good things about it and the powder seems to be easy to find compared to 2400 or other powders.

zxcvbob the link you posted isn't letting me in. It's asking me to log in again and then says that my login info is invalid. Maybe PM it to me or something?

I'm new to metallic cartridge, and currently using Green Dot for both 45 Colt and 9mm. I orig wanted to use Unique ... but all I could find was Green Dot.

It's actually worked out pretty well. Stuff doesn't "meter" all that well, but I'm only loading for personal plinking so extreme accuracy isn't a big deal.

45 Colt 255gr semi-wad cuter, 6.1 - 6.8 gr of green dot. at 6.3 I'm getting about 800 fps out of a 4" Taurus Judge, and about 1000 fps out of a Rossi Lever action rifle.

It's a nice mild, low recoil load that's fun to shoot.

WWW.loadbooks.com publishes a compilation of loads by cartridge type, and has lots of green dot loads for 45 Colt.

Red Dot is the only powder I use in all my handguns from .32 to 44Mag incl .45 LC. Have had no problems with it at all. ( Also use it for large rifle caliber target loads)

Lyman #49 has both Red Dot and Green Dot load data for .45 Colt using 200, 230, 250, and 255 grain cast bullets.

Max loads they list for a 200 grain LSWC is:
Red Dot - 6.9 = 975 @ 11,800 CUP.
Green Dot - 7.7 = 1,028 @ 12,500 CUP.

Neither Red Dot or Green Dot are suitable for "Magnumizing" the .45 Colt or any other caliber, as they are both too fast burning, and will reach peak pressure and spike over without much warning.

Website is a bit odd (as in badly designed) as he uses yellow text on a white background, and light gray text on a white background.

Got some red dot.

Gonna load up some 200 grain LRNFP with 6.0, 6.2, and 6.4 to start with. Can't find anything directly for a LRNFP but was told that cast lead data is good for most bullet types as long as the weight is the same. My OAL is going to be a little longer because of the bullet I'm using. 1.567" is what I'm averaging.

Neither Red Dot or Green Dot are suitable for "Magnumizing" the .45 ColtThey are good for economically stretching the top end a little. But for real .45 Colt "magnum" loads, I like to use Herco or 2400 (Herco is cheaper, 2400 can be loaded hotter)

from my experience R.D. is very close to BullsEye but much cleaner. and has more 'bulk'. I'm fond of it for my cast slug 'target' loads. a 'from data' .357mag 158gr cast swc gives 1200, slightly more fps from a 6" mdl 28.
I nearly missed trying it. one of my b-in-laws is a shotgun reloader and uses it extensively. he gave me 4 oz to try it out. it's very good for .380acp, .32acp, 9mm Mak and 9mm Para the cast slug loads. and .357.

Walked out and tried the loads I made. 6.2 takes it again so far. Gonna make a few more of those to compare with 6.6 and 6.8. Red dot seems to be a little sharper in terms of recoil. Looked like a little more "flame-age" from the barrel too. Me likey muzzle blast.

So which is the predominant factor in recoil anyway? Heavier bullet, more pressure?

Pressure has little to do with it.

You could have a faster load producing less pressure. (2400 powder)
Or, a slower load producing more pressure. (Red Dot powder)

All else being the same, a 200 at 1,000 kicks the same as a 250 at 800.

Go here and play around.

Velocity, bullet weight, and charge weight = recoil.

Perceived recoil is another thing. Some can feel sharper while technically having less recoil than another load.
