Tite Group for WB rifle power factor.

[Ol Salty Sailor]

I am looking for load data for .45 Colt to make the power factor on WB classic.

I use Tite Group for almost everything

I reload 200 gr RNFP Hi-Tec coated bullets.  20" barrel 1873 rifle.

How much Tite Group will result in muzzle velocity of >750fps but <800fps?

I have used TG in a lot of .45 Colt loads.  I never worried much about the velocity because all my 200 grain loads easily made a power factor of 165 - close to 180.   I ran 6.2 grains of TG.

But I suggest you start with 5.7 grains.  Your load "velocity requirement range" is kinda slow - so with the chamber diameter and even bore variances, you will need to chrono the load.  It will be a sooty load and probably not seal the chamber very well.  Keeping the gas blow back down to a livable level out of Uberti toggle gun was the main reason I ran about 6.2 grains - that was enough chamber pressure to seal a .45 Colt case, even if not annealed.   

good luck, GJ

Quickload puts the number at 3.2-3.4 grains, which generates about 3,000 PSI of chamber pressure.  I doubt any powder is going to burn clean at that pressure.

I test fired some across my chrono yesterday. 45 Colt with a 180gr bullet loaded with 5.0grs of Titegroup. Produced an average of 836fps. 

If you do the math this setup results in a 150.48 power factor. I will end up increasing the powder charge a little bit.
