I picked up a box of Speer Deep Curl .308, 180 grain bullets in Winnipeg at Cabelas. There is a warning in the box to only use their receipts located on their website. It states:
"DeepCurl's unique construction process joins the jacket to the core at the molecular level for excellent performance and consistency. For this reason conventional reloading data developed for standard jacketed bullets should not be used to load DeepCurl bullets. Only DeepCurl specific reloading data released by Speer Bullets should be used".
I checked the Speer website and found the receipts for 180 grain 308 Winchester but it doesn't list H4895 powder but does list IMR4895.
I checked the Hodgdon website and they don't list Deep Curl bullets. The burning rate for the two powders are very close with IMR4895 being slightly faster (Hornaday manual).
My question, anyone have any experience loading 180 grain Deep Curl bullets in a 308 Winchester using H4895 powder?
Is this warning something I should be concerned with?
If I use H4895 powder were would you start your load at?
I wanted to have a 2400 fps load for deer hunting.
I also sent a email to Speer asking them about the H4895 powder.
