If any of you have some Hornady .358 158 grain XTP bullets, could you give me the dimension from the base to the approximate center of the cannelure?

Thanks

I have some but would be Sunday before I can furnish the measurement. I'm travelling.

From the base of the bullet to the middle of the cannelure measured with my calipers I get 0.3765! And by the way Hornaday 38 caliber, 158 grn XTP ( Hornaday #35750) have a listed diameter of .357 not .358!

The difference may be the ones I have are hornady#35780. They are skived hollow points, but have fp/xtp in the description. Cheap digital caliper and old eyes, still show .354.

In a situation such as this ... who do you believe ?
.354" .... or .3765" that's a .0225 difference ...?

We need a couple more measurements ... I don't have any to measure !

Hornady 35780 are labeled flat points. They have a small hollow point compared to the 35750. I have 35750, but no 35780’s.

It is the 35750 I am interested in. Sorry for any confusion.

On my 35750, I get 0.341" to the bottom of the cannelure and 0.381" to the top. Mid-point would then be 0.361" on my bullets

And I got 0.343 and 0.385 so midpoint 0.364

Not sure I have the eyes to be anymore precise but three thousands longer than rockrat and 1 thousandth less than poppy. It is right around there though.
