Missing Reloading Data

[mattiooo]

I need some help with load data that's not in the Western Powders loading data book. I am loading 45 Colt and I'm using Missouri Bullet Company Cowboy #1 bullets. They are powder coated lead bullets and 250 grains. The load data for Accurate #5 only has plated bullets for 250 grain and lead bullets are 255 grains. There is no lead option for 250 grains. Also, I have some True Blue I want to test, and the load data has no 250 grain option at all. Just lead 255 grain.

I've emailed Western Powders and I am waiting for a response, but does this information exist somewhere? Missouri Bullet doesn't provide load data for their bullets. I've looked in the Laser-cast load data, but they don't have Western Powders in it.

Thanks,
Matt

**as always use internet load data as a consult only** always check multiple sources- NOT my info below My favorite is Clays for a clean burning load.

## new Cowboy load from Hodgdon
AA5744 is most consistent powder I have found, point up or down in case before firing.
Less "position sensitive." Titegroup performs well.
New (2005) Trail Boss is very bulky and very consistent.

My favorite is 6.8gr of ETR7 (4 5/8") Vaquero barrels at 768 fps with an SD of 9

The powder coated bullets are going to behave just like ordinary lead bullets for reloading purposes. I would go ahead and start with the 255 grain lead bullet data. The 255 grain lead bullet is only about 2% heavier - which is pretty close to the error range of 250 grain powder coated bullets I suspect.

Just use starting loads for the 250 and go from there.
