After playing with my Darr FBW in 32-40, I'm starting to realize that Ramshot Enforcer may not be the best powder for this cartridge. Using the same case for a match, after 30 ish shots, the case collapses and gets very dimpled about 1/3rd of the way back.

The rifle came with load data for W296 for the Brooks 200gr mold (13.9gr). From what I can see h110 is the same powder? For testing, would it be a 1:1 substitute? Asking because I have h110 on hand

Little early for a stiff drink Jack?

H110/296 are the same powder. If you are at the top end of pressure for a load, treat it like a new lot of powder and back off the charge weight a little. I don’t think your near max pressure with that load.

During the great powder shortage of 2012-16 and purchases were limited, I often bought my limit in both powders. Most of the time it was the same lot number. 
Before all the nonsense I tried to buy 296 as Winchester powders were generally about 10% less in cost than Hodgdon. Same for 231/HP38.

I've posted on this before but, back when they were sold by different company's (Win/Olin vs Hodgdon), The only difference between H110 and Win 296, was that Olin, made it and when sold as 296, it was "Closed Bomb" test by them, before packaging and selling it. 

Hodgdon bought it in bulk, w/o closed bomb testing and sold it as H110. It varied in loading data, because of that. Once Hodgdon got the rights to it, they sell it under different names but, it's the same powder, that's why in all later Hodgdon, it has the exact same pressure and velocity.

I do not know, now that Hodgdon has the rights to it, if Hodgdon close bomb tests it before selling it.

In a strong rifle, you can shoot as much as 15.2 gr, with a 217 gr PB, BSed bullet and get excellent accuracy. I have shot 16.2 gr, with a 187 gr BSed bullet and 1/2" groups @ 100.

It's not primer sensitive either. I have shot 12.5 gr, 208 gr bullet, using F150 pistol primers and got 2.5 SD and 6 fps ES.

It was them helmet landings.

Did you mean to write duck tape?

I got no ducks that need taping.  But Duck Tape might fly better.

Try changing primers.

I've always used F150's but, try a few different ones.
