Speer 190gr HPBT Match coefficient?

[atreeman]

Hi, I bought a good number of these bullets a little while ago and cannot find a published coefficient for them anywhere. Does anyone happen to have it to hand? I'm currently working up a load in my .308 and it would be advantageous to have the correct coefficient rather than doing a SWAG calculation.

Thanks in advance

Speer does't list a 190 Match... When and where did you get them?

They made them for years.

Good luck

I got them about two years ago on a close out deal from a local gunshop. Got 350 of them for the price of 1 box of normal bullets. I might email speer and ask them directly but I haven't had good luck with response from Speer in the past.

BC of .540 per our 1992 Speer Bullets catalog. Linda Linda OlinCCI/Speer Technical Services2299 Snake River Ave.Lewiston, ID 83501

That's the reply I just got.
Excellent response time from Speer.

Now to go to the ballistic tables.

Supersonic to 900 from a 20" barrel. That will do for now.
