I have Titegroup currently and will look into 231

You'll probably find that 231 is the closer of the two as compared to Sport Pistol (in terms of burn rate and load data).  It's a fair bit dirtier though.  I used to use 231 exclusively for 9mm until I switched to Sport Pistol.  Nothing wrong with Titegroup either.

In my testing of sport pistol it is a reformulation of Bullseye.

same charge by weight produces the some velocity with in 2 FPS.

Volume is different but weight is the same.

So recommend Bullseye till you can get sport pistol

According to the powder "burn rate" charts, Sport Pistol is somewhat slower than Bullseye and, in fact, is slightly slower than Titegroup.   The fact that Alliant lists no 9 mm loads for Bullseye but numerous ones for Sport Pistol tends to support that they aren't that close in properties.

Have printed data for Bullseye and 9mm.

Where bid you find a burn rate chart with sport pistol?

My findings are from actual use.

It depends on what you mean by reformulation.

BE-86 and Power Pistol are the same basic compound as Bullseye, with different particle sizes and shapes and different additives and coatings and whatnot to create different burn rates and different desired characteristics.

I have seen nothing about this being the case with Sport Pistol.

I didn't but Alliant states its burn rate between two of their current powders (American Select and Green Dot) and the burn rate charts list those. 

 

I did some more searching and Alliant does indeed publish data for 9 mm loads using Bullseye and the recommended charge weights are very similar to Sport Pistol and Titegroup.  So, while Sport Pistol isn't a modified Bullseye, it fits into then same usage range.

Nevermind.  I see now that you don't mean that it's a reformulation OF Bullseye, but that it's supposed to duplicate Bullseye's performance with some new characteristics.  

yes and so far chrono data confirms this.       the smoke is a little lighter with SP  and  weight of charges are the same in 9mm so far
