358156 hp
At large, whereabouts unknown.
296/H110 are volume sensitive powders. They require a specific loading density to perform properly, which is why they should never be reduced beyond published data. For hollowpoints I use the loading data of the parent design since case intrusion by the bullet base is a major factor.Tight group, W296, and H110 make me nervous.
With the "Cheerios" powders I ain't scared a notin'.
Just wish I could find 8 lb of those fluffy little round donuts in some brand or other.
You mentioned a 452374 HP. Is this a Devastator? Lyman drastically reshaped the original bullet design to create the Devastator, this included cutting the bullet weight by about 10%. I think the 452374 Devastator weights 200 gr, instead of 230. However, the standard 452374 HP is roughly around 220 gr. I haven't bought any Devastator moulds because I feel Lyman reduced the weight of the original design too much to generate expansion. The bullet noses seem a bit too thin for serious use, especially in my beloved 1911 and their rather drastic feed angle from the magazine. However, they do expand readily with the right alloys.
