Continuing the W231 off-subject tangent
There is one huge drawback to W231 -- aside from the ten pounds you have stashed, Nick, it's extremely rare to see more than a pound or two appearing anywhere under one roof.
It is hard to find; due to its popularity, no doubt. It's amusing that HP-38 tends to sell slower than W231 - just a side observation. Cabela's has 1# available right now. And they have had 8#'s available for the longest time (where I got my 8#er). The 8#'s are on backorder now; but they had it available for many months. Brick n mortar stores may be tougher. But I have seen them (W231 & HP-38) available a time or two since the '13 panic.
I've got all of W231's bases covered with the powders I've got.
I have no doubt. I currently have the bases covered too - with AA#2 and TiteGroup. But I won't be buying any more of either. Same with Bullseye, except I have exhausted my supply of B'eye.
And for the record... W231 will never do the one thing that Titegroup is crazy-good at doing... being completely insensitive to powder position and being a tiny smidge of charge in a massive case. Nothing I have ever tried will do what Titegroup does in this regard.
I heard the same thing (on Hodgdon's website), so I put the theory to test . . .
38 Special. Smith Model 67; 4" bbl. Missouri Bullet Co soft cast "PPC#2"(BNH-10) 148gn DEWC. 2.8gn TiteGroup. I shot six (6) 10-round groups; alternating between tilting the gun back (shifting the powder against the primer) prior to shooting each round, and not. Here's the results:
1, no tilt: 700 f/s; 15.81 SD
2, tilt: 726 f/s; 10.19 SD
3, no tilt: 700 f/s; 24.22 SD
4, tilt: 722 f/s; 13.37 SD
5, no tilt: 706 f/s; 25.23 SD
6, tilt: 725 f/s ; 11.13 SD
(edit: Standard Deviation data added)
That's the data. Digest it as you will. Position made a difference of some 21 f/s. So yes, there was a difference. A significant difference? Eh. I've never conducted such a test with other propellants; so there's no comparative baseline. I post this not to dispute the claim; but just for the sake of sharing actual "real world" data. Albeit, probably not all that scientific.
