I need some help with 310 grain bullets in 358 Norma, ist any here that has pictures of them expended ? The COL in the Norma data from 1995 is on 80mm, but that is too short, i think at least , i have set some dummies at 83.5 mm.

And the bullets i have they doesnt have a cannelure on them, but the nes bullets that Midway has in their store has them.

When was that changed ?

Put a dummy rd together and experiment. The rd will look short as the blunt nose hits the lands as opposed to a spitzer rd. I still have a stash of 300 gr barnes originals that are pretty close to the Woodleighs.

I have loaded them to 3.330" and they shoot really well from my rifle. My load using IMR 4831 get 2550fps and about an inch @ 100yds from my LeadSled.
