I'm interested in loading some bp rounds in my .45 colt revolver. Will the lube on the Hornady swaged lead 255 grain boolits work with black powder or will I have to go with a boolit with with grease grooves and use a suitable black powder lube?

I have shot those bullets when I didn't have any cast available using Trailboss. They are tumble lubed with a smokeless lube. They do not have any lube grooves on them instead using a checkered pattern to hold the lube on the bullet.

They are fine using smokeless, but carry the wrong lube for BP. I would not use them myself with BP as they would probably foul out the weapon in a very few rounds.

With BP, the Lyman 454190 with a good BP lube is what I have found to work the best in my Rugers. It carries plenty of lube.

The only way you could use them is with a lube cookie of BP lube under the bullet. You can load them in a 45 colt easy enough by dropping say 28 to 30 gr of BP add a card wad then lube cookie then a news print wad then the bullet. This will provide enough lube for the bore so as to get more than a few shots before you loose all accuracy and lead plate your bore. A greese groove bullet lubed with BP lube works good too.

I would not use the bullet as it will still have the factory lube on it and may cause a mess that will be hard to remove.
I used the 45 Colt in SASS with nothing but BP and fired many types to test the best one for me.
That turned out to be a custom mould bullet made by Hoch moulds that I designed.
The best stock bullets were the Lyman 454190 which is a copy of the original bullet loaded in 1873 and the RCBS 45-230-CM. Both carry enough lube for revolver shooting.
You will need to use a good BP lube like the NASA made by Bullshop, SPG or a homemade version that you may use by pan lubing or in a lube/sizer.
If you decide to commit to it on a full time bases then I would suggest that you have a mould made by Tom at Accurate moulds.

everybody is right they are not for bp. I tryed em in my ruger not the right lube and definitely not enough. My rcbs 45-255 keith works great with bp better accuracy then some good smokless loads i like.Thirty five grs.fffg goex the smoke and sound are awesome.
