Hornady .224 HPBT

[Southwind]

I bought 400 horn. 75gr hpbt seconds from powder valley. I weighed all of them and came out with 53 that are the 68gr hpbt. I measured the overall length and they are almost the same size as the 75gr bullets. Oal was .985 while the average of the 75's were .990".

Does this sound right? I figured the 68's would be noticeably shorter than the 75's.

Only other thing I have to compare to is the 69gr smk which is quite a bit shorter than either of these hornady's.

Thx, Steve

They probably have bubbles in the cores if the profiles are otherwise exact, I can't see .005 giving up 7gr.

Maybe some 68s got mixed up with the 75's in the packing frenzy.

The 68s and 75s have the EXACT same exterior dimensions. The difference is internal.

Let me see if I can dig a picture up...

Here you go...

Thx for the info. So because of the length, do I just use my load data for the 75gr or can I use my data for the 69gr smk and seat it as long as I seat the 75gr?

There is no data for the 68gr bullet on the imr/Hodgon site.

Well, I was sort of right...

Thanks for the picture!

I would load for the 69, lacking any other data. (usual disclaimers in place here).
