ExactlyShouldn't be an issue, unless you're loading at/near max, then you'll need to back off a little and work it back up.

It is at max in the Hornady manual. I'm using the data for a 158 gr lead SWC and using 4.4 gr of HP-38. Its supposed to deliver 850 fps out of a 4" barrel and I'm getting 750 fps out of a 6" barrel. Using the data for a 158 gr Hornady XTP I'm about midrange. Those velocities are closer to what I'm getting than the lead bullet data.Exactly
I was trying to avoid that, but dropping back to the next lower load wouldn't be a big deal.Sounds like you are OK, but I would back off, load a few, work up with a few each step.
I don't crimp Barry's bullets much. I've deconstructed a few mistakes and there's barely a line on the bullet.And make sure to only crimp enough so that the cartridges drop into the cylinders, or just a touch more. Plated bullets like as little crimp as possible.
Thanks, I guess I'll drop back one load and run the chronograph to see what's what.I think you're okay. Wouldnt hurt to work up again, but... provided the bullets do not set deeper, I probably wouldn't myself. That said, I'm comfortable and familiar with both 38 Special and W231.
They are probably seated deeper to maintain the same OAL. Personally, you can seat them out some, to fit the length of your cylinder. Just not so long as to protrude past the front of the cylinder.Well, I did a little research. Berrys says the length of the 158 gr. FP is .636, but I measured ten of them and they are all .647. They don’t list a length for the target HP, but I measured .677 on ten bullets. Berry’s calls for the same COAL for both, 1.430. I would have thought the longer bullets would result in a longer COAL.
