Looks very simmilar, but the Speer is a flat base bullet and the Fusion is a boattail.
Heres how to get some load info from Speer concerning ''mollecularly bonded'' (just like Fusion) bullets.

Important Reloading Data
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. It can be found by contacting Speer Technical Services at 866-286-7436.

Im a big fan of the performance of the Fusion bullet. However I never did stack a critter at long range with them. Dont know if they'd open. I prefer Accubomds for my idea of L/R with my 270wsm, but Id love to find some Fusions for my 30-06, 300wby, and maybe even my 338win mag. Great track record on game Ive taken. Great bullet. Looks like Speers DeepCurl should be very simmilar.
