anybody using Blue Dot for 45 ACP?

I'm working on finding a good load for my new 45. I have Bullseye, Power Pistol and Blue Dot on hand.

I've already done one round of testing with the Bullseye. I'm going to do a series with Power Pistol this weekend. I noticed the Lyman book has Blue Dot data for .45 ACP so I'm thinking about giving that a shot too. I don't use it much anymore, just when I do some 9mm rounds specifically for the carbine.

Anybody like/dislike Blue Dot for .45?

after

I use Blue Dot in 10mm medium-weight-jacketed-bullet loads ONLY.
Works great for that.


And that is why I have 21 handgun powders on my shelves.

Blue Dot can be used for .45 ACP, but it would be the third choice of the three powders you have on hand. It is on the slow side as burn rates go - up there with AA #9 and 2400 neither of which are good choices for that caliber either.

You'll use almost twice as much of it to get good bullet velocity, and I have no proof of this in your gun, but I'll bet a good portion of it burns outside the barrel or even goes unburned.

My favorite would be the Bullseye.

I'd stick with Bullseye for the light loads,and PP for +P loads in .45ACP.

Blue Dot is also my third choice. With a 230 gr. jacketed bullet 8.1-9.0 gr. will work.

Have used the lower amount of powder with 200/230 gr. lead.

The benefit is less leading. The down side is if you are near max. on hot days pressures will rise with Blue Dot.

I started using Blue Dot when reloading supplies could not be found, and I had a bunch of Blue Dot. I can't argue with what the others have said, but I find it to work very well.

I tried Blue Dot in two different M1911's.

I don't like the stuff. Based on the hard recoil and long case ejection, breech pressures are just too high at unlock.

I have had a Colt M1911 frame peen out, I don't want to lose another frame due to hard recoiling ammunition.

Blue Dot might just be great for something like a Thompson Machine Gun, where the breech block is huge, but for my handguns, not the best.

It is my considered belief that what you want in a short recoil system, like most handguns, is a fast burning powder which gives a sharp kick to the mechanism with a quick pressure drop.

Bullseye has been filling the ticket for 45ACP ammo since 1910. It is the original 45 ACP powder.

Something like Blue Dot, which is a slow burning powder and has high breech pressures at unlock, not appropriate.

My data is below. I posted my Bullseye data which was shot on the same day as the 64 rounds of Blue Dot. Chronograph only goes to 32 rounds (stupid gits at Chrony), so I fired two 32 shot strings.

For a M1911, I want my 230's to be just at 800 fps.

Thanks for the replies!

I think I'm going to skip the Blue Dot for now. It works great in my carbine (which has a pretty massive bolt) but early results with Bullseye are pretty good so I'm going to try and refine that.

Until I get a better light rigged up for inspecting powder charges in my progressive press, I'm going to stick with the single stage when I'm working with Bullseye.

I'll also test the Power Pistol and work up to see how it handles heavier loads. PP is pretty much all I use for my 9mm handguns so I always have it around.

Your descision needs to be based on the amount of recoil from higher velcoties you are wiling to tollerate. If you want a goof full house load for a jacketed round, then you are going in the right direction. Other wise, go for the faster buring powders that will enable you to load lower velocities without excessive pressures.
